| Cisco IOS 12.2T through 12.4 allows remote attackers to bypass Authentication, Authorization, and Accounting (AAA) RADIUS authentication, if the fallback method is set to none, via a long username. | ||||
| CVE-2002-1357 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-04-16 | N/A |
| Multiple SSH2 servers and clients do not properly handle packets or data elements with incorrect length specifiers, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite. | ||||
| CVE-2004-0054 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| 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. | ||||
| CVE-2005-1021 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| 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. | ||||
| CVE-2000-0984 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| The HTTP server in Cisco IOS 12.0 through 12.1 allows local users to cause a denial of service (crash and reload) via a URL containing a "?/" string. | ||||
| CVE-1999-1175 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Web Cache Control Protocol (WCCP) in Cisco Cache Engine for Cisco IOS 11.2 and earlier does not use authentication, which allows remote attackers to redirect HTTP traffic to arbitrary hosts via WCCP packets to UDP port 2048. | ||||
| CVE-1999-1306 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 9.1 and earlier does not properly handle extended IP access lists when the IP route cache is enabled and the "established" keyword is set, which could allow attackers to bypass filters. | ||||
| CVE-2003-1109 | 1 Cisco | 4 Ios, Ip Phone 7940, Ip Phone 7960 and 1 more | 2026-04-16 | N/A |
| The Session Initiation Protocol (SIP) implementation in multiple Cisco products including IP Phone models 7940 and 7960, IOS versions in the 12.2 train, and Secure PIX 5.2.9 to 6.2.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted INVITE messages, as demonstrated by the OUSPG PROTOS c07-sip test suite. | ||||
| CVE-2001-0537 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| HTTP server for Cisco IOS 11.3 to 12.2 allows attackers to bypass authentication and execute arbitrary commands, when local authorization is being used, by specifying a high access level in the URL. | ||||
| CVE-2005-3921 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| 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. | ||||
| CVE-2001-0650 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco devices IOS 12.0 and earlier allow a remote attacker to cause a crash, or bad route updates, via malformed BGP updates with unrecognized transitive attribute. | ||||
| CVE-1999-0160 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections. | ||||
| CVE-1999-1465 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Vulnerability in Cisco IOS 11.1 through 11.3 with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled input interface to an output interface with a logical subinterface, as described by Cisco bug CSCdk43862. | ||||
| CVE-2000-0268 | 1 Cisco | 12 3660 Router, 7100 Router, 7200 Router and 9 more | 2026-04-16 | N/A |
| Cisco IOS 11.x and 12.x allows remote attackers to cause a denial of service by sending the ENVIRON option to the Telnet daemon before it is ready to accept it, which causes the system to reboot. | ||||
| CVE-2005-1058 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.2T, 12.3 and 12.3T, when processing an ISAKMP profile that specifies XAUTH authentication after Phase 1 negotiation, may not process certain attributes in the ISAKMP profile that specifies XAUTH, which allows remote attackers to bypass XAUTH and move to Phase 2 negotiations. | ||||
| CVE-1999-0230 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
