The TCL shell in Cisco IOS 12.2(14)S before 12.2(14)S16, 12.2(18)S before 12.2(18)S11, and certain other releases before 25 January 2006 does not perform Authentication, Authorization, and Accounting (AAA) command authorization checks, which may allow local users to execute IOS EXEC commands that were prohibited via the AAA configuration, aka Bug ID CSCeh73049.
CVE-2004-1111 1 Cisco 10 7200 Router, 7300 Router, 7500 Router and 7 more 2026-04-16 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-2005-1020 1 Cisco 1 Ios 2026-04-16 N/A
Secure Shell (SSH) 2 in Cisco IOS 12.0 through 12.3 allows remote attackers to cause a denial of service (device reload) (1) via a username that contains a domain name when using a TACACS+ server to authenticate, (2) when a new SSH session is in the login phase and a currently logged in user issues a send command, or (3) when IOS is logging messages and an SSH session is terminated while the server is sending data.
CVE-2005-2105 1 Cisco 1 Ios 2026-04-16 N/A
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-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-2001-0711 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 11.x and 12.0 with ATM support allows attackers to cause a denial of service via the undocumented Interim Local Management Interface (ILMI) SNMP community string.
CVE-2001-1183 1 Cisco 1 Ios 2026-04-16 N/A
PPTP implementation in Cisco IOS 12.1 and 12.2 allows remote attackers to cause a denial of service (crash) via a malformed packet.
CVE-2005-0195 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.0S through 12.3YH allows remote attackers to cause a denial of service (device restart) via a crafted IPv6 packet.
CVE-2004-0589 1 Cisco 1 Ios 2026-04-16 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-2004-0244 1 Cisco 1 Ios 2026-04-16 N/A
Cisco 6000, 6500, and 7600 series systems with Multilayer Switch Feature Card 2 (MSFC2) and a FlexWAN or OSM module allow local users to cause a denial of service (hang or reset) by sending a layer 2 frame packet that encapsulates a layer 3 packet, but has inconsistent length values with that packet.
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-2003-0100 1 Cisco 1 Ios 2026-04-16 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-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2026-04-16 N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-1999-0157 1 Cisco 2 Ios, Pix Firewall Software 2026-04-16 N/A
Cisco PIX firewall and CBAC IP fragmentation attack results in a denial of service.
CVE-2002-2315 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 11.2.x and 12.0.x does not limit the size of its redirect table, which allows remote attackers to cause a denial of service (memory consumption) via spoofed ICMP redirect packets to the router.
CVE-2004-0081 23 4d, Apple, Avaya and 20 more 67 Webstar, Mac Os X, Mac Os X Server and 64 more 2026-04-16 N/A
OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.
CVE-2003-0851 3 Cisco, Openssl, Redhat 7 Css11000 Content Services Switch, Ios, Pix Firewall and 4 more 2026-04-16 N/A
