CVSS v3.1 |
| PPTP implementation in Cisco IOS 12.1 and 12.2 allows remote attackers to cause a denial of service (crash) via a malformed packet. |
| Cisco IOS 12.0(5)XU through 12.1(2) allows remote attackers to read system administration and topology information via an "snmp-server host" command, which creates a readable "community" community string if one has not been previously created. |
| Cisco IOS 11.1CC through 12.2 with Cisco Express Forwarding (CEF) enabled includes portions of previous packets in the padding of a MAC level packet when the MAC packet's length is less than the IP level packet length. |
| Cisco IOS software 11.3 through 12.2 running on Cisco uBR7200 and uBR7100 series Universal Broadband Routers allows remote attackers to modify Data Over Cable Service Interface Specification (DOCSIS) settings via a DOCSIS file without a Message Integrity Check (MIC) signature, which is approved by the router. |
| Cisco 2611 router running IOS 12.1(6.5), possibly an interim release, allows remote attackers to cause a denial of service via port scans such as (1) scanning all ports on a single host and (2) scanning a network of hosts for a single open port through the router. NOTE: the vendor could not reproduce this issue, saying that the original reporter was using an interim release of the software. |
| OpenSSL 0.9.6k allows remote attackers to cause a denial of service (crash via large recursion) via malformed ASN.1 sequences. |
| Cisco IOS 12.0 through 12.2, when IP routing is disabled, accepts false ICMP redirect messages, which allows remote attackers to cause a denial of service (network routing modification). |
| Multiple vulnerabilities in the H.323 protocol implementation for Cisco IOS 11.3T through 12.2T allow remote attackers to cause a denial of service and possibly execute arbitrary code, as demonstrated by the NISCC/OUSPG PROTOS test suite for the H.225 protocol. |
| Secure Shell (SSH) 2 in Cisco IOS 12.0 through 12.3 allows remote attackers to cause a denial of service (device reload) (1) via a username that contains a domain name when using a TACACS+ server to authenticate, (2) when a new SSH session is in the login phase and a currently logged in user issues a send command, or (3) when IOS is logging messages and an SSH session is terminated while the server is sending data. |
| Memory leak in Secure Shell (SSH) in Cisco IOS 12.0 through 12.3, when authenticating against a TACACS+ server, allows remote attackers to cause a denial of service (memory consumption) via an incorrect username or password. |
| Cisco IOS 12.0 through 12.4 and IOS XR before 3.2, with IPv6 enabled, allows remote attackers on a local network segment to cause a denial of service (device reload) and possibly execute arbitrary code via a crafted IPv6 packet. |
| Cisco IOS 12.0 to 12.4 might allow remote attackers to execute arbitrary code via a heap-based buffer overflow in system timers. NOTE: this issue does not correspond to a specific vulnerability, rather a general weakness that only increases the feasibility of exploitation of any vulnerabilities that might exist. Such design-level weaknesses normally are not included in CVE, so perhaps this issue should be REJECTed. |
| Multiple unspecified vulnerabilities in the Internet Key Exchange version 1 (IKEv1) implementation in multiple Cisco products allow remote attackers to cause a denial of service (device reset) via certain malformed IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the Cisco advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to. |
| Cross-site scripting (XSS) vulnerability in Cisco IOS Web Server for IOS 12.0(2a) allows remote attackers to inject arbitrary web script or HTML by (1) packets containing HTML that an administrator views via an HTTP interface to the contents of memory buffers, as demonstrated by the URI /level/15/exec/-/buffers/assigned/dump; or (2) sending the router Cisco Discovery Protocol (CDP) packets with HTML payload that an administrator views via the CDP status pages. NOTE: these vectors were originally reported as being associated with the dump and packet options in /level/15/exec/-/show/buffers. |
| Unspecified vulnerability in the VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(22)EA3 on Catalyst 2950T switches allows remote attackers to cause a denial of service (device reboot) via a crafted Subset-Advert message packet, a different issue than CVE-2006-4774, CVE-2006-4775, and CVE-2006-4776. |
| The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) allows remote attackers to cause a denial of service by sending a VTP version 1 summary frame with a VTP version field value of 2. |
| The web interface on Cisco IOS 12.3(8)JA and 12.3(8)JA1, as used on the Cisco Wireless Access Point and Wireless Bridge, reconfigures itself when it is changed to use the "Local User List Only (Individual Passwords)" setting, which removes all security and password configurations and allows remote attackers to access the system. |
| Cisco IOS 2.2(18)EW, 12.2(18)EWA, 12.2(14)SZ, 12.2(18)S, 12.2(18)SE, 12.2(18)SV, 12.2(18)SW, and other versions without the "no service dhcp" command, keep undeliverable DHCP packets in the queue instead of dropping them, which allows remote attackers to cause a denial of service (dropped traffic) via multiple undeliverable DHCP packets that exceed the input queue size. |
| Cisco Internetwork Operating System (IOS) 12.0S through 12.3T attempts to process SNMP solicited operations on improper ports (UDP 162 and a randomly chosen UDP port), which allows remote attackers to cause a denial of service (device reload and memory corruption). |
| A vulnerability in the application-hosting subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to root on an affected device. The attacker could execute IOS XE commands outside the application-hosting subsystem Docker container as well as on the underlying Linux operating system. These commands could be run as the root user. The vulnerability is due to a combination of two factors: (a) incomplete input validation of the user payload of CLI commands, and (b) improper role-based access control (RBAC) when commands are issued at the command line within the application-hosting subsystem. An attacker could exploit this vulnerability by using a CLI command with crafted user input. A successful exploit could allow the lower-privileged attacker to execute arbitrary CLI commands with root privileges. The attacker would need valid user credentials to exploit this vulnerability. |
