CVE-2021-33026 1 Flask-caching Project 1 Flask-caching 2024-11-21 9.8 Critical
The Flask-Caching extension through 1.10.1 for Flask relies on Pickle for serialization, which may lead to remote code execution or local privilege escalation. If an attacker gains access to cache storage (e.g., filesystem, Memcached, Redis, etc.), they can construct a crafted payload, poison the cache, and execute Python code. NOTE: a third party indicates that exploitation is extremely unlikely unless the machine is already compromised; in other cases, the attacker would be unable to write their payload to the cache and generate the required collision
CVE-2021-32836 1 Zstack 1 Zstack 2024-11-21 7.5 High
ZStack is open source IaaS(infrastructure as a service) software. In ZStack before versions 3.10.12 and 4.1.6 there is a pre-auth unsafe deserialization vulnerability in the REST API. An attacker in control of the request body will be able to provide both the class name and the data to be deserialized and therefore will be able to instantiate an arbitrary type and assign arbitrary values to its fields. This issue may lead to a Denial Of Service. If a suitable gadget is available, then an attacker may also be able to exploit this vulnerability to gain pre-auth remote code execution. For additional details see the referenced GHSL-2021-087.
CVE-2021-32833 1 Emby 1 Emby.releases 2024-11-21 8.6 High
Emby Server is a personal media server with apps on many devices. In Emby Server on Windows there is a set of arbitrary file read vulnerabilities. This vulnerability is known to exist in version 4.6.4.0 and may not be patched in later versions. Known vulnerable routes are /Videos/Id/hls/PlaylistId/SegmentId.SegmentContainer, /Images/Ratings/theme/name and /Images/MediaInfo/theme/name. For more details including proof of concept code, refer to the referenced GHSL-2021-051. This issue may lead to unauthorized access to the system especially when Emby Server is configured to be accessible from the Internet.
CVE-2021-32825 1 Bblfshd Project 1 Bblfshd 2024-11-21 2.7 Low
bblfshd is an open source self-hosted server for source code parsing. In bblfshd before commit 4265465b9b6fb5663c30ee43806126012066aad4 there is a "zipslip" vulnerability. The unsafe handling of symbolic links in an unpacking routine may enable attackers to read and/or write to arbitrary locations outside the designated target folder. This issue may lead to arbitrary file write (with same permissions as the program running the unpack operation) if the attacker can control the archive file. Additionally, if the attacker has read access to the unpacked files, he may be able to read arbitrary system files the parent process has permissions to read. For more details including a PoC see the referenced GHSL-2020-258.
CVE-2021-32822 1 Hbs Project 1 Hbs 2024-11-21 4 Medium
The npm hbs package is an Express view engine wrapper for Handlebars. Depending on usage, users of hbs may be vulnerable to a file disclosure vulnerability. There is currently no patch for this vulnerability. hbs mixes pure template data with engine configuration options through the Express render API. By overwriting internal configuration options a file disclosure vulnerability may be triggered in downstream applications. For an example PoC see the referenced GHSL-2021-020.
CVE-2021-32803 4 Oracle, Redhat, Siemens and 1 more 8 Graalvm, Acm, Enterprise Linux and 5 more 2024-11-21 8.2 High
The npm package "tar" (aka node-tar) before versions 6.1.2, 5.0.7, 4.4.15, and 3.2.3 has an arbitrary File Creation/Overwrite vulnerability via insufficient symlink protection. `node-tar` aims to guarantee that any file whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by ensuring that extracted directories are not symlinks. Additionally, in order to prevent unnecessary `stat` calls to determine whether a given path is a directory, paths are cached when directories are created. This logic was insufficient when extracting tar files that contained both a directory and a symlink with the same name as the directory. This order of operations resulted in the directory being created and added to the `node-tar` directory cache. When a directory is present in the directory cache, subsequent calls to mkdir for that directory are skipped. However, this is also where `node-tar` checks for symlinks occur. By first creating a directory, and then replacing that directory with a symlink, it was thus possible to bypass `node-tar` symlink checks on directories, essentially allowing an untrusted tar file to symlink into an arbitrary location and subsequently extracting arbitrary files into that location, thus allowing arbitrary file creation and overwrite. This issue was addressed in releases 3.2.3, 4.4.15, 5.0.7 and 6.1.2.
CVE-2021-32801 1 Nextcloud 1 Nextcloud Server 2024-11-21 5.5 Medium
Nextcloud server is an open source, self hosted personal cloud. In affected versions logging of exceptions may have resulted in logging potentially sensitive key material for the Nextcloud Encryption-at-Rest functionality. It is recommended that the Nextcloud Server is upgraded to 20.0.12, 21.0.4 or 22.1.0. If upgrading is not an option users are advised to disable system logging to resolve this issue until such time that an upgrade can be performed Note that ff you do not use the Encryption-at-Rest functionality of Nextcloud you are not affected by this bug.
CVE-2021-32779 2 Envoyproxy, Redhat 2 Envoy, Service Mesh 2024-11-21 8.6 High
Envoy is an open source L7 proxy and communication bus designed for large modern service oriented architectures. In affected versions envoy incorrectly handled a URI '#fragment' element as part of the path element. Envoy is configured with an RBAC filter for authorization or similar mechanism with an explicit case of a final "/admin" path element, or is using a negative assertion with final path element of "/admin". The client sends request to "/app1/admin#foo". In Envoy prior to 1.18.0, or 1.18.0+ configured with path_normalization=false. Envoy treats fragment as a suffix of the query string when present, or as a suffix of the path when query string is absent, so it evaluates the final path element as "/admin#foo" and mismatches with the configured "/admin" path element. In Envoy 1.18.0+ configured with path_normalization=true. Envoy transforms this to /app1/admin%23foo and mismatches with the configured /admin prefix. The resulting URI is sent to the next server-agent with the offending "#foo" fragment which violates RFC3986 or with the nonsensical "%23foo" text appended. A specifically constructed request with URI containing '#fragment' element delivered by an untrusted client in the presence of path based request authorization resulting in escalation of Privileges when path based request authorization extensions. Envoy versions 1.19.1, 1.18.4, 1.17.4, 1.16.5 contain fixes that removes fragment from URI path in incoming requests.
CVE-2021-32777 2 Envoyproxy, Redhat 2 Envoy, Service Mesh 2024-11-21 8.6 High
Envoy is an open source L7 proxy and communication bus designed for large modern service oriented architectures. In affected versions when ext-authz extension is sending request headers to the external authorization service it must merge multiple value headers according to the HTTP spec. However, only the last header value is sent. This may allow specifically crafted requests to bypass authorization. Attackers may be able to escalate privileges when using ext-authz extension or back end service that uses multiple value headers for authorization. A specifically constructed request may be delivered by an untrusted downstream peer in the presence of ext-authz extension. Envoy versions 1.19.1, 1.18.4, 1.17.4, 1.16.5 contain fixes to the ext-authz extension to correctly merge multiple request header values, when sending request for authorization.
CVE-2021-32770 1 Gatsbyjs 1 Gatsby-source-wordpress 2024-11-21 7.5 High
Gatsby is a framework for building websites. The gatsby-source-wordpress plugin prior to versions 4.0.8 and 5.9.2 leaks .htaccess HTTP Basic Authentication variables into the app.js bundle during build-time. Users who are not initializing basic authentication credentials in the gatsby-config.js are not affected. A patch has been introduced in gatsby-source-wordpress@4.0.8 and gatsby-source-wordpress@5.9.2 which mitigates the issue by filtering all variables specified in the `auth: { }` section. Users that depend on this functionality are advised to upgrade to the latest release of gatsby-source-wordpress, run `gatsby clean` followed by a `gatsby build`. One may manually edit the app.js file post-build as a workaround.
CVE-2021-32767 1 Typo3 1 Typo3 2024-11-21 5.3 Medium
TYPO3 is an open source PHP based web content management system. In versions 9.0.0 through 9.5.27, 10.0.0 through 10.4.17, and 11.0.0 through 11.3.0, user credentials may been logged as plain-text. This occurs when explicitly using log level debug, which is not the default configuration. TYPO3 versions 9.5.28, 10.4.18, 11.3.1 contain a patch for this vulnerability.
CVE-2021-32753 1 Edgexfoundry 1 Edgex Foundry 2024-11-21 8.3 High
EdgeX Foundry is an open source project for building a common open framework for internet-of-things edge computing. A vulnerability exists in the Edinburgh, Fuji, Geneva, and Hanoi versions of the software. When the EdgeX API gateway is configured for OAuth2 authentication and a proxy user is created, the client_id and client_secret required to obtain an OAuth2 authentication token are set to the username of the proxy user. A remote network attacker can then perform a dictionary-based password attack on the OAuth2 token endpoint of the API gateway to obtain an OAuth2 authentication token and use that token to make authenticated calls to EdgeX microservices from an untrusted network. OAuth2 is the default authentication method in EdgeX Edinburgh release. The default authentication method was changed to JWT in Fuji and later releases. Users should upgrade to the EdgeX Ireland release to obtain the fix. The OAuth2 authentication method is disabled in Ireland release. If unable to upgrade and OAuth2 authentication is required, users should create OAuth2 users directly using the Kong admin API and forgo the use of the `security-proxy-setup` tool to create OAuth2 users.
CVE-2021-32752 1 Ethercreative 1 Logs 2024-11-21 7.2 High
Ether Logs is a package that allows one to check one's logs in the Craft 3 utilities section. A vulnerability was found in versions prior to 3.0.4 that allowed authenticated admin users to access any file on the server. The vulnerability has been fixed in version 3.0.4. As a workaround, one may disable the plugin if untrustworthy sources have admin access.
CVE-2021-32742 1 Vapor Project 1 Vapor 2024-11-21 7.5 High
Vapor is a web framework for Swift. In versions 4.47.1 and prior, bug in the `Data.init(base32Encoded:)` function opens up the potential for exposing server memory and/or crashing the server (Denial of Service) for applications where untrusted data can end up in said function. Vapor does not currently use this function itself so this only impact applications that use the impacted function directly or through other dependencies. The vulnerability is patched in version 4.47.2. As a workaround, one may use an alternative to Vapor's built-in `Data.init(base32Encoded:)`.
CVE-2021-32724 1 Check-spelling 1 Check-spelling 2024-11-21 9.9 Critical
check-spelling is a github action which provides CI spell checking. In affected versions and for a repository with the [check-spelling action](https://github.com/marketplace/actions/check-spelling) enabled that triggers on `pull_request_target` (or `schedule`), an attacker can send a crafted Pull Request that causes a `GITHUB_TOKEN` to be exposed. With the `GITHUB_TOKEN`, it's possible to push commits to the repository bypassing standard approval processes. Commits to the repository could then steal any/all secrets available to the repository. As a workaround users may can either: [Disable the workflow](https://docs.github.com/en/actions/managing-workflow-runs/disabling-and-enabling-a-workflow) until you've fixed all branches or Set repository to [Allow specific actions](https://docs.github.com/en/github/administering-a-repository/managing-repository-settings/disabling-or-limiting-github-actions-for-a-repository#allowing-specific-actions-to-run). check-spelling isn't a verified creator and it certainly won't be anytime soon. You could then explicitly add other actions that your repository uses. Set repository [Workflow permissions](https://docs.github.com/en/github/administering-a-repository/managing-repository-settings/disabling-or-limiting-github-actions-for-a-repository#setting-the-permissions-of-the-github_token-for-your-repository) to `Read repository contents permission`. Workflows using `check-spelling/check-spelling@main` will get the fix automatically. Workflows using a pinned sha or tagged version will need to change the affected workflows for all repository branches to the latest version. Users can verify who and which Pull Requests have been running the action by looking up the spelling.yml action in the Actions tab of their repositories, e.g., https://github.com/check-spelling/check-spelling/actions/workflows/spelling.yml - you can filter PRs by adding ?query=event%3Apull_request_target, e.g., https://github.com/check-spelling/check-spelling/actions/workflows/spelling.yml?query=event%3Apull_request_target.
CVE-2021-32688 2 Fedoraproject, Nextcloud 2 Fedora, Nextcloud Server 2024-11-21 8.8 High
Nextcloud Server is a Nextcloud package that handles data storage. Nextcloud Server supports application specific tokens for authentication purposes. These tokens are supposed to be granted to a specific applications (e.g. DAV sync clients), and can also be configured by the user to not have any filesystem access. Due to a lacking permission check, the tokens were able to change their own permissions in versions prior to 19.0.13, 20.0.11, and 21.0.3. Thus fileystem limited tokens were able to grant themselves access to the filesystem. The issue is patched in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds aside from upgrading.
CVE-2021-32634 1 Nsa 1 Emissary 2024-11-21 7.2 High
Emissary is a distributed, peer-to-peer, data-driven workflow framework. Emissary 6.4.0 is vulnerable to Unsafe Deserialization of post-authenticated requests to the [`WorkSpaceClientEnqueue.action`](https://github.com/NationalSecurityAgency/emissary/blob/30c54ef16c6eb6ed09604a929939fb9f66868382/src/main/java/emissary/server/mvc/internal/WorkSpaceClientEnqueueAction.java) REST endpoint. This issue may lead to post-auth Remote Code Execution. This issue has been patched in version 6.5.0. As a workaround, one can disable network access to Emissary from untrusted sources.
CVE-2021-32610 4 Debian, Fedoraproject, Php and 1 more 4 Debian Linux, Fedora, Archive Tar and 1 more 2024-11-21 7.1 High
In Archive_Tar before 1.4.14, symlinks can refer to targets outside of the extracted archive, a different vulnerability than CVE-2020-36193.
CVE-2021-32570 1 Ericsson 1 Network Manager 2024-11-21 4.9 Medium
In Ericsson Network Manager (ENM) releases before 21.2, users belonging to the same AMOS authorization group can retrieve the data from certain log files. All AMOS users are considered to be highly privileged users in ENM system and all must be previously defined and authorized by the Security Administrator. Those users can access some log’s files, under a common path, and read information stored in the log’s files in order to conduct privilege escalation.
CVE-2021-32568 1 Mrdoc 1 Mrdoc 2024-11-21 7.8 High
mrdoc is vulnerable to Deserialization of Untrusted Data
