| The Cisco Network Admission Control (NAC) 3.6.4.1 and earlier allows remote attackers to prevent installation of the Cisco Clean Access (CCA) Agent and bypass local and remote protection mechanisms by modifying (1) the HTTP User-Agent header or (2) the behavior of the TCP/IP stack. NOTE: the vendor has disputed the severity of this issue, stating that users cannot bypass authentication mechanisms. | ||||
| CVE-2001-0566 | 1 Cisco | 1 Catalyst 2900 | 2026-04-16 | N/A |
| Cisco Catalyst 2900XL switch allows a remote attacker to create a denial of service via an empty UDP packet sent to port 161 (SNMP) when SNMP is disabled. | ||||
| CVE-2002-0769 | 1 Cisco | 1 Ata-186 | 2026-04-16 | N/A |
| The web-based configuration interface for the Cisco ATA 186 Analog Telephone Adaptor allows remote attackers to bypass authentication via an HTTP POST request with a single byte, which allows the attackers to (1) obtain the password from the login screen, or (2) reconfigure the adaptor by modifying certain request parameters. | ||||
| CVE-1999-0159 | 1 Cisco | 1 Ios | 2026-04-16 | 3.5 Low |
