| 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-2006-3290 | 1 Cisco | 1 Wireless Control System | 2026-04-16 | N/A |
| HTTP server in Cisco Wireless Control System (WCS) for Linux and Windows before 3.2(51) stores sensitive information under the web root with insufficient access control, which allows remote attackers to obtain usernames and directory paths via a direct URL request. | ||||
| CVE-2006-3291 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| The web interface on Cisco IOS 12.3(8)JA and 12.3(8)JA1, as used on the Cisco Wireless Access Point and Wireless Bridge, reconfigures itself when it is changed to use the "Local User List Only (Individual Passwords)" setting, which removes all security and password configurations and allows remote attackers to access the system. | ||||
| CVE-2004-1435 | 1 Cisco | 1 Optical Networking Systems Software | 2026-04-16 | N/A |
