| CVE-2007-5549 | 1 Cisco | 1 Ios | 2026-04-23 | N/A |
| Unspecified vulnerability in Command EXEC in Cisco IOS allows local users to bypass command restrictions and obtain sensitive information via an unspecified "variation of an IOS command" involving "two different methods", aka CSCsk16129. 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-2008-4128 | 1 Cisco | 2 871 Integrated Services Router, Ios | 2026-04-23 | N/A |
| Multiple cross-site request forgery (CSRF) vulnerabilities in the HTTP Administration component in Cisco IOS 12.4 on the 871 Integrated Services Router allow remote attackers to execute arbitrary commands via (1) a certain "show privilege" command to the /level/15/exec/- URI, and (2) a certain "alias exec" command to the /level/15/exec/-/configure/http URI. NOTE: some of these details are obtained from third party information. | ||||
| CVE-2007-5381 | 1 Cisco | 1 Ios | 2026-04-23 | N/A |
| Stack-based buffer overflow in the Line Printer Daemon (LPD) in Cisco IOS before 12.2(18)SXF11, 12.4(16a), and 12.4(2)T6 allow remote attackers to execute arbitrary code by setting a long hostname on the target system, then causing an error message to be printed, as demonstrated by a telnet session to the LPD from a source port other than 515. | ||||
| CVE-2007-2688 | 1 Cisco | 2 Ios, Ips Sensor Software | 2026-04-23 | N/A |
| The Cisco Intrusion Prevention System (IPS) and IOS with Firewall/IPS Feature Set do not properly handle certain full-width and half-width Unicode character encodings, which might allow remote attackers to evade detection of HTTP traffic. | ||||
| CVE-2007-4291 | 1 Cisco | 1 Ios | 2026-04-23 | N/A |
| Cisco IOS 12.0 through 12.4 allows remote attackers to cause a denial of service via (1) a malformed MGCP packet, which causes a device hang, aka CSCsf08998; a malformed H.323 packet, which causes a device crash, as identified by (2) CSCsi60004 with Proxy Unregistration and (3) CSCsg70474; and a malformed Real-time Transport Protocol (RTP) packet, which causes a device crash, as identified by (4) CSCse68138, related to VOIP RTP Lib, and (5) CSCse05642, related to I/O memory corruption. | ||||
| CVE-2007-5551 | 1 Cisco | 1 Ios | 2026-04-23 | 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-2007-4295 | 1 Cisco | 1 Ios | 2026-04-23 | N/A |
