| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2000-0380 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| The IOS HTTP service in Cisco routers and switches running IOS 11.1 through 12.1 allows remote attackers to cause a denial of service by requesting a URL that contains a %% string. | ||||
| CVE-2005-3481 | 1 Cisco | 1 Ios | 2026-04-16 | 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-2002-1360 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-04-16 | N/A |
| Multiple SSH2 servers and clients do not properly handle strings with null characters in them when the string length is specified by a length field, which could allow remote attackers to cause a denial of service or possibly execute arbitrary code due to interactions with the use of null-terminated strings as implemented using languages such as C, as demonstrated by the SSHredder SSH protocol test suite. | ||||
| CVE-1999-1465 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Vulnerability in Cisco IOS 11.1 through 11.3 with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled input interface to an output interface with a logical subinterface, as described by Cisco bug CSCdk43862. | ||||
| CVE-1999-1464 | 1 Cisco | 1 Ios | 2026-04-16 | 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-2003-0647 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Buffer overflow in the HTTP server for Cisco IOS 12.2 and earlier allows remote attackers to execute arbitrary code via an extremely long (2GB) HTTP GET request. | ||||
| CVE-2002-1359 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-04-16 | N/A |
| Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite. | ||||
| 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 |
| 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-2003-1398 | 1 Cisco | 1 Ios | 2026-04-16 | 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-2006-4775 | 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-2002-1357 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-04-16 | 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-2002-1358 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-04-16 | N/A |
| Multiple SSH2 servers and clients do not properly handle lists with empty elements or strings, 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-2005-4258 | 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-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-2006-4774 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) allows remote attackers to cause a denial of service by sending a VTP version 1 summary frame with a VTP version field value of 2. | ||||
| CVE-2000-0368 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Classic Cisco IOS 9.1 and later allows attackers with access to the login prompt to obtain portions of the command history of previous users, which may allow the attacker to access sensitive data. | ||||
| CVE-2002-2208 | 2 Cisco, Extended Interior Gateway Routing Protocol | 2 Ios, Extended Interior Gateway Routing Protocol | 2026-04-16 | N/A |
| Extended Interior Gateway Routing Protocol (EIGRP), as implemented in Cisco IOS 11.3 through 12.2 and other products, allows remote attackers to cause a denial of service (flood) by sending a large number of spoofed EIGRP neighbor announcements, which results in an ARP storm on the local network. | ||||
| CVE-1999-0293 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| AAA authentication on Cisco systems allows attackers to execute commands without authorization. | ||||
