CVE-2008-3813 1 Cisco 1 Ios 2025-04-09 7.8 HIGH N/A
Unspecified vulnerability in Cisco IOS 12.2 and 12.4, when the L2TP mgmt daemon process is enabled, allows remote attackers to cause a denial of service (device reload) via a crafted L2TP packet.
CVE-2008-4128 1 Cisco 2 871 Integrated Services Router, Ios 2025-04-09 9.3 HIGH 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-2007-5552 1 Cisco 1 Ios 2025-04-09 9.3 HIGH N/A
Integer overflow in Cisco IOS allows remote attackers to execute arbitrary code via unspecified vectors. 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-2007-0917 1 Cisco 1 Ios 2025-04-09 6.4 MEDIUM N/A
The Intrusion Prevention System (IPS) feature for Cisco IOS 12.4XE to 12.3T allows remote attackers to bypass IPS signatures that use regular expressions via fragmented packets.
CVE-2007-4292 1 Cisco 1 Ios 2025-04-09 9.3 HIGH N/A
Multiple memory leaks in Cisco IOS 12.0 through 12.4 allow remote attackers to cause a denial of service (device crash) via a malformed SIP packet, aka (1) CSCsf11855, (2) CSCeb21064, (3) CSCse40276, (4) CSCse68355, (5) CSCsf30058, (6) CSCsb24007, and (7) CSCsc60249.
CVE-2007-2688 1 Cisco 2 Ios, Ips Sensor Software 2025-04-09 7.8 HIGH 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-2009-2866 1 Cisco 1 Ios 2025-04-09 7.8 HIGH N/A
Unspecified vulnerability in Cisco IOS 12.2 through 12.4 allows remote attackers to cause a denial of service (device reload) via a crafted H.323 packet, aka Bug ID CSCsz38104.
CVE-2009-0631 1 Cisco 1 Ios 2025-04-09 7.8 HIGH N/A
Unspecified vulnerability in Cisco IOS 12.0 through 12.4, when configured with (1) IP Service Level Agreements (SLAs) Responder, (2) Session Initiation Protocol (SIP), (3) H.323 Annex E Call Signaling Transport, or (4) Media Gateway Control Protocol (MGCP) allows remote attackers to cause a denial of service (blocked input queue on the inbound interface) via a crafted UDP packet.
CVE-2006-4776 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Heap-based buffer overflow in the VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) allows remote attackers to execute arbitrary code via a long VLAN name in a VTP type 2 summary advertisement.
CVE-2001-0929 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Cisco IOS Firewall Feature set, aka Context Based Access Control (CBAC) or Cisco Secure Integrated Software, for IOS 11.2P through 12.2T does not properly check the IP protocol type, which could allow remote attackers to bypass access control lists.
CVE-1999-0160 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections.
CVE-2001-1071 1 Cisco 2 Catos, Ios 2025-04-03 5.0 MEDIUM N/A
Cisco IOS 12.2 and earlier running Cisco Discovery Protocol (CDP) allows remote attackers to cause a denial of service (memory consumption) via a flood of CDP neighbor announcements.
CVE-2005-3481 1 Cisco 1 Ios 2025-04-03 9.3 HIGH 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-2003-1398 1 Cisco 1 Ios 2025-04-03 9.3 HIGH N/A
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).
CVE-2006-0340 1 Cisco 1 Ios 2025-04-03 7.1 HIGH N/A
Unspecified vulnerability in Stack Group Bidding Protocol (SGBP) support in Cisco IOS 12.0 through 12.4 running on various Cisco products, when SGBP is enabled, allows remote attackers on the local network to cause a denial of service (device hang and network traffic loss) via a crafted UDP packet to port 9900.
CVE-1999-0161 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
In Cisco IOS 10.3, with the tacacs-ds or tacacs keyword, an extended IP access control list could bypass filtering.
