| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2003-0512 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| Cisco IOS 12.2 and earlier generates a "% Login invalid" message instead of prompting for a password when an invalid username is provided, which allows remote attackers to identify valid usernames on the system and conduct brute force password guessing, as reported for the Aironet Bridge. | ||||
| CVE-2003-0567 | 1 Cisco | 3 Ios, Ons 15454 Optical Transport Platform, Optical Networking Systems Software | 2025-04-03 | 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-2005-2105 | 1 Cisco | 1 Ios | 2025-04-03 | 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-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-2002-2053 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| The design of the Hot Standby Routing Protocol (HSRP), as implemented on Cisco IOS 12.1, when using IRPAS, allows remote attackers to cause a denial of service (CPU consumption) via a router with the same IP address as the interface on which HSRP is running, which causes a loop. | ||||
| CVE-2005-3481 | 1 Cisco | 1 Ios | 2025-04-03 | 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-2002-2052 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| Cisco 2611 router running IOS 12.1(6.5), possibly an interim release, allows remote attackers to cause a denial of service via port scans such as (1) scanning all ports on a single host and (2) scanning a network of hosts for a single open port through the router. NOTE: the vendor could not reproduce this issue, saying that the original reporter was using an interim release of the software. | ||||
| CVE-2005-4258 | 1 Cisco | 71 Catalyst, Catalyst 1200 Series, Catalyst 1900 Series and 68 more | 2025-04-03 | 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-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-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-2006-4775 | 1 Cisco | 2 Catos, Ios | 2025-04-03 | 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-2001-1434 | 1 Cisco | 1 Ios | 2025-04-03 | 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-2003-0647 | 1 Cisco | 1 Ios | 2025-04-03 | 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-2002-2315 | 1 Cisco | 1 Ios | 2025-04-03 | 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-2003-0305 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| The Service Assurance Agent (SAA) in Cisco IOS 12.0 through 12.2, aka Response Time Reporter (RTR), allows remote attackers to cause a denial of service (crash) via malformed RTR packets to port 1967. | ||||
| 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-2004-0054 | 1 Cisco | 1 Ios | 2025-04-03 | 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-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. | ||||
| CVE-2006-4650 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| Cisco IOS 12.0, 12.1, and 12.2, when GRE IP tunneling is used and the RFC2784 compliance fixes are missing, does not verify the offset field of a GRE packet during decapsulation, which leads to an integer overflow that references data from incorrect memory locations, which allows remote attackers to inject crafted packets into the routing queue, possibly bypassing intended router ACLs. | ||||
| CVE-2004-0710 | 1 Cisco | 1 Ios | 2025-04-03 | N/A |
| IP Security VPN Services Module (VPNSM) in Cisco Catalyst 6500 Series Switch and the Cisco 7600 Series Internet Routers running IOS before 12.2(17b)SXA, before 12.2(17d)SXB, or before 12.2(14)SY03 could allow remote attackers to cause a denial of service (device crash and reload) via a malformed Internet Key Exchange (IKE) packet. | ||||
