Cross-site request forgery (CSRF) vulnerability in the HTTP server in Cisco IOS 12.4(23) allows remote attackers to execute arbitrary commands, as demonstrated by executing the hostname command with a level/15/configure/-/hostname request.
CVE-2008-3810 1 Cisco 1 Ios 2025-04-09 7.8 HIGH N/A
Cisco IOS 12.2 and 12.4, when NAT Skinny Call Control Protocol (SCCP) Fragmentation Support is enabled, allows remote attackers to cause a denial of service (device reload) via segmented SCCP messages, aka CSCsg22426, a different vulnerability than CVE-2008-3811.
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-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-2008-1151 1 Cisco 1 Ios 2025-04-09 7.1 HIGH N/A
Memory leak in the virtual private dial-up network (VPDN) component in Cisco IOS before 12.3 allows remote attackers to cause a denial of service (memory consumption) via a series of PPTP sessions, related to "dead memory" that remains allocated after process termination, aka bug ID CSCsj58566.
CVE-2004-0714 1 Cisco 3 Ios, Ons 15454e Optical Transport Platform, Optical Networking Systems Software 2025-04-03 5.0 MEDIUM N/A
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).
CVE-2004-0589 1 Cisco 1 Ios 2025-04-03 4.3 MEDIUM N/A
Cisco IOS 11.1(x) through 11.3(x) and 12.0(x) through 12.2(x), when configured for BGP routing, allows remote attackers to cause a denial of service (device reload) via malformed BGP (1) OPEN or (2) UPDATE messages.
CVE-2003-0100 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Buffer overflow in Cisco IOS 11.2.x to 12.0.x allows remote attackers to cause a denial of service and possibly execute commands via a large number of OSPF neighbor announcements.
CVE-1999-1129 1 Cisco 2 Catalyst 2900 Vlan, Ios 2025-04-03 7.5 HIGH N/A
Cisco Catalyst 2900 Virtual LAN (VLAN) switches allow remote attackers to inject 802.1q frames into another VLAN by forging the VLAN identifier in the trunking tag.
CVE-2001-1434 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
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.
CVE-1999-1464 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Vulnerability in Cisco IOS 11.1CC and 11.1CT with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled interface to an interface that does not have DFS enabled, as described by Cisco bug CSCdk35564.
CVE-1999-0016 6 Cisco, Gnu, Hp and 3 more 8 Ios, Inet, Hp-ux and 5 more 2025-04-03 5.0 MEDIUM N/A
Land IP denial of service.
CVE-2006-3906 1 Cisco 21 Adaptive Security Appliance Software, Ios, Pix Asa Ids and 18 more 2025-04-03 5.0 MEDIUM N/A
Internet Key Exchange (IKE) version 1 protocol, as implemented on Cisco IOS, VPN 3000 Concentrators, and PIX firewalls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of IKE Phase-1 packets that exceed the session expiration rate. NOTE: it has been argued that this is due to a design weakness of the IKE version 1 protocol, in which case other vendors and implementations would also be affected.
CVE-2005-1021 1 Cisco 1 Ios 2025-04-03 7.1 HIGH 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-2001-0537 1 Cisco 1 Ios 2025-04-03 9.3 HIGH 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 5.0 MEDIUM 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-2004-0081 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2025-04-03 5.0 MEDIUM N/A
