CVE-2007-5551 1 Cisco 1 Ios 2025-04-09 N/A
Off-by-one error in Cisco IOS allows remote attackers to execute arbitrary code via unspecified vectors that trigger a heap-based buffer overflow. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.
CVE-2007-5550 1 Cisco 1 Ios 2025-04-09 N/A
Unspecified vulnerability in Cisco IOS allows remote attackers to obtain the IOS version via unspecified vectors involving a "common network service", aka PSIRT-1255024833. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.
CVE-2001-1097 1 Cisco 1 Ios 2025-04-03 N/A
Cisco routers and switches running IOS 12.0 through 12.2.1 allows a remote attacker to cause a denial of service via a flood of UDP packets.
CVE-2001-0537 1 Cisco 1 Ios 2025-04-03 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-2004-1775 1 Cisco 2 Catos, Ios 2025-04-03 N/A
Cisco VACM (View-based Access Control MIB) for Catalyst Operating Software (CatOS) 5.5 and 6.1 and IOS 12.0 and 12.1 allows remote attackers to read and modify device configuration via the read-write community string.
CVE-2001-0288 1 Cisco 1 Ios 2025-04-03 N/A
Cisco switches and routers running IOS 12.1 and earlier produce predictable TCP Initial Sequence Numbers (ISNs), which allows remote attackers to spoof or hijack TCP connections.
CVE-2004-1111 1 Cisco 10 7200 Router, 7300 Router, 7500 Router and 7 more 2025-04-03 N/A
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.
CVE-2005-3481 1 Cisco 1 Ios 2025-04-03 N/A
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.
CVE-2005-4258 1 Cisco 71 Catalyst, Catalyst 1200 Series, Catalyst 1900 Series and 68 more 2025-04-03 N/A
