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-2003-0511 1 Cisco 1 Ios 2025-04-03 N/A
The web server for Cisco Aironet AP1x00 Series Wireless devices running certain versions of IOS 12.2 allow remote attackers to cause a denial of service (reload) via a malformed URL.
CVE-2001-0650 1 Cisco 1 Ios 2025-04-03 N/A
Cisco devices IOS 12.0 and earlier allow a remote attacker to cause a crash, or bad route updates, via malformed BGP updates with unrecognized transitive attribute.

Cisco IOS 11.x and 12.0 through 12.2 allows remote attackers to cause a denial of service (traffic block) by sending a particular sequence of IPv4 packets to an interface on the device, causing the input queue on that interface to be marked as full.
CVE-2003-1398 1 Cisco 1 Ios 2025-04-03 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-2004-1454 1 Cisco 1 Ios 2025-04-03 N/A
Cisco IOS 12.0S, 12.2, and 12.3, with Open Shortest Path First (OSPF) enabled, allows remote attackers to cause a denial of service (device reload) via a malformed OSPF packet.
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-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-2002-1357 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2025-04-03 N/A
Multiple SSH2 servers and clients do not properly handle packets or data elements with incorrect length specifiers, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2005-4826 1 Cisco 1 Ios 2025-04-03 N/A
Unspecified vulnerability in the VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(22)EA3 on Catalyst 2950T switches allows remote attackers to cause a denial of service (device reboot) via a crafted Subset-Advert message packet, a different issue than CVE-2006-4774, CVE-2006-4775, and CVE-2006-4776.

Cisco IOS 12.1YD, 12.2T, 12.3 and 12.3T, when configured for the IOS Telephony Service (ITS), CallManager Express (CME) or Survivable Remote Site Telephony (SRST), allows remote attackers to cause a denial of service (device reboot) via a malformed packet to the SCCP port.
CVE-2005-0195 1 Cisco 1 Ios 2025-04-03 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-1999-1306 1 Cisco 1 Ios 2025-04-03 N/A
Cisco IOS 9.1 and earlier does not properly handle extended IP access lists when the IP route cache is enabled and the "established" keyword is set, which could allow attackers to bypass filters.
CVE-2004-0589 1 Cisco 1 Ios 2025-04-03 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.
