CVE-2021-22339 1 Huawei 1 Manageone 2024-11-21 6.5 Medium
There is a denial of service vulnerability in some versions of ManageOne. In specific scenarios, due to the insufficient verification of the parameter, an attacker may craft some specific parameter. Successful exploit may cause some services abnormal.
CVE-2021-22160 1 Apache 1 Pulsar 2024-11-21 9.8 Critical
If Apache Pulsar is configured to authenticate clients using tokens based on JSON Web Tokens (JWT), the signature of the token is not validated if the algorithm of the presented token is set to "none". This allows an attacker to connect to Pulsar instances as any user (incl. admins).
CVE-2021-21739 1 Zte 2 Zxctn 6120h, Zxctn 6120h Firmware 2024-11-21 4.6 Medium
A ZTE's product of the transport network access layer has a security vulnerability. Because the system does not sufficiently verify the data reliability, attackers could replace an authenticated optical module on the equipment with an unauthenticated one, bypassing system authentication and detection, thus affecting signal transmission. This affects: <ZXCTN 6120H><V5.10.00B24>
CVE-2021-21588 1 Dell 1 Powerflex Presentation Server 2024-11-21 6.5 Medium
Dell EMC PowerFlex, v3.5.x contain a Cross-Site WebSocket Hijacking Vulnerability in the Presentation Server/WebUI. An unauthenticated attacker could potentially exploit this vulnerability by tricking the user into performing unwanted actions on the Presentation Server and perform which may lead to configuration changes.
CVE-2021-21405 1 Filecoin 1 Lotus 2024-11-21 5.9 Medium
Lotus is an Implementation of the Filecoin protocol written in Go. BLS signature validation in lotus uses blst library method VerifyCompressed. This method accepts signatures in 2 forms: "serialized", and "compressed", meaning that BLS signatures can be provided as either of 2 unique byte arrays. Lotus block validation functions perform a uniqueness check on provided blocks. Two blocks are considered distinct if the CIDs of their blockheader do not match. The CID method for blockheader includes the BlockSig of the block. The result of these issues is that it would be possible to punish miners for valid blocks, as there are two different valid block CIDs available for each block, even though this must be unique. By switching from the go based `blst` bindings over to the bindings in `filecoin-ffi`, the code paths now ensure that all signatures are compressed by size and the way they are deserialized. This happened in https://github.com/filecoin-project/lotus/pull/5393.
CVE-2021-21374 1 Nim-lang 1 Nim 2024-11-21 8.1 High
Nimble is a package manager for the Nim programming language. In Nim release versions before versions 1.2.10 and 1.4.4, "nimble refresh" fetches a list of Nimble packages over HTTPS without full verification of the SSL/TLS certificate due to the default setting of httpClient. An attacker able to perform MitM can deliver a modified package list containing malicious software packages. If the packages are installed and used the attack escalates to untrusted code execution.
CVE-2021-21373 1 Nim-lang 1 Nim 2024-11-21 7.5 High
Nimble is a package manager for the Nim programming language. In Nim release versions before versions 1.2.10 and 1.4.4, "nimble refresh" fetches a list of Nimble packages over HTTPS by default. In case of error it falls back to a non-TLS URL http://irclogs.nim-lang.org/packages.json. An attacker able to perform MitM can deliver a modified package list containing malicious software packages. If the packages are installed and used the attack escalates to untrusted code execution.
CVE-2021-21320 1 Matrix-react-sdk Project 1 Matrix-react-sdk 2024-11-21 2.6 Low
matrix-react-sdk is an npm package which is a Matrix SDK for React Javascript. In matrix-react-sdk before version 3.15.0, the user content sandbox can be abused to trick users into opening unexpected documents. The content is opened with a `blob` origin that cannot access Matrix user data, so messages and secrets are not at risk. This has been fixed in version 3.15.0.
CVE-2021-21239 2 Debian, Pysaml2 Project 2 Debian Linux, Pysaml2 2024-11-21 6.5 Medium
PySAML2 is a pure python implementation of SAML Version 2 Standard. PySAML2 before 6.5.0 has an improper verification of cryptographic signature vulnerability. Users of pysaml2 that use the default CryptoBackendXmlSec1 backend and need to verify signed SAML documents are impacted. PySAML2 does not ensure that a signed SAML document is correctly signed. The default CryptoBackendXmlSec1 backend is using the xmlsec1 binary to verify the signature of signed SAML documents, but by default xmlsec1 accepts any type of key found within the given document. xmlsec1 needs to be configured explicitly to only use only _x509 certificates_ for the verification process of the SAML document signature. This is fixed in PySAML2 6.5.0.
CVE-2021-21238 1 Pysaml2 Project 1 Pysaml2 2024-11-21 6.5 Medium
PySAML2 is a pure python implementation of SAML Version 2 Standard. PySAML2 before 6.5.0 has an improper verification of cryptographic signature vulnerability. All users of pysaml2 that need to validate signed SAML documents are impacted. The vulnerability is a variant of XML Signature wrapping because it did not validate the SAML document against an XML schema. This allowed invalid XML documents to be processed and such a document can trick pysaml2 with a wrapped signature. This is fixed in PySAML2 6.5.0.
