| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2005-07-05 | CVE-2005-2105 | Security Bypass vulnerability in IOS 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. | 7.5 |
| 2005-05-02 | CVE-2005-1058 | Unspecified vulnerability in Cisco IOS 12.2T/12.3/12.3T Cisco IOS 12.2T, 12.3 and 12.3T, when processing an ISAKMP profile that specifies XAUTH authentication after Phase 1 negotiation, may not process certain attributes in the ISAKMP profile that specifies XAUTH, which allows remote attackers to bypass XAUTH and move to Phase 2 negotiations. | 7.5 |
| 2005-05-02 | CVE-2005-1057 | Unspecified vulnerability in Cisco IOS 12.2T/12.3/12.3T Cisco IOS 12.2T, 12.3 and 12.3T, when using Easy VPN Server XAUTH version 6 authentication, allows remote attackers to bypass authentication via a "malformed packet." | 7.5 |
| 2005-05-02 | CVE-2005-1021 | Resource Management Errors vulnerability in Cisco IOS 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. | 7.1 |
| 2005-05-02 | CVE-2005-1020 | Improper Authentication vulnerability in Cisco IOS 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. | 7.1 |
| 2004-11-23 | CVE-2004-0079 | NULL Pointer Dereference vulnerability in multiple products The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference. | 7.5 |
| 2004-02-17 | CVE-2004-0054 | Unspecified vulnerability in Cisco IOS 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. | 7.5 |
| 2003-12-31 | CVE-2003-1109 | Unspecified vulnerability in Cisco products The Session Initiation Protocol (SIP) implementation in multiple Cisco products including IP Phone models 7940 and 7960, IOS versions in the 12.2 train, and Secure PIX 5.2.9 to 6.2.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted INVITE messages, as demonstrated by the OUSPG PROTOS c07-sip test suite. | 7.5 |
| 2003-08-27 | CVE-2003-0647 | Remote Security vulnerability in IOS 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. | 7.5 |
| 2003-08-18 | CVE-2003-0567 | Improper Input Validation vulnerability in Cisco products 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. | 7.8 |
