| CVE-2005-3921 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cross-site scripting (XSS) vulnerability in Cisco IOS Web Server for IOS 12.0(2a) allows remote attackers to inject arbitrary web script or HTML by (1) packets containing HTML that an administrator views via an HTTP interface to the contents of memory buffers, as demonstrated by the URI /level/15/exec/-/buffers/assigned/dump; or (2) sending the router Cisco Discovery Protocol (CDP) packets with HTML payload that an administrator views via the CDP status pages. NOTE: these vectors were originally reported as being associated with the dump and packet options in /level/15/exec/-/show/buffers. | ||||

| 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-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-2003-0511 | 1 Cisco | 1 Ios | 2026-04-16 | 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-1999-0161 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| In Cisco IOS 10.3, with the tacacs-ds or tacacs keyword, an extended IP access control list could bypass filtering. | ||||
| CVE-2001-0288 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco switches and routers running IOS 12.1 and earlier produce predictable TCP Initial Sequence Numbers (ISNs), which allows remote attackers to spoof or hijack TCP connections. | ||||
| CVE-2003-0567 | 1 Cisco | 3 Ios, Ons 15454 Optical Transport Platform, Optical Networking Systems Software | 2026-04-16 | N/A |
| 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-2005-4258 | 1 Cisco | 71 Catalyst, Catalyst 1200 Series, Catalyst 1900 Series and 68 more | 2026-04-16 | N/A |
| Unspecified Cisco Catalyst Switches allow remote attackers to cause a denial of service (device crash) via an IP packet with the same source and destination IPs and ports, and with the SYN flag set (aka LanD). NOTE: the provenance of this issue is unknown; the details are obtained solely from the BID. | ||||
| CVE-2006-4775 | 1 Cisco | 2 Catos, Ios | 2026-04-16 | N/A |
| The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) and CatOS allows remote attackers to cause a denial of service by sending a VTP update with a revision value of 0x7FFFFFFF, which is incremented to 0x80000000 and is interpreted as a negative number in a signed context. | ||||
| 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-2006-0340 | 1 Cisco | 1 Ios | 2026-04-16 | 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-2005-4826 | 1 Cisco | 1 Ios | 2026-04-16 | 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. | ||||
| CVE-2006-4776 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
