goform/websXMLAdminRequestCgi.cgi in Cisco Unified Videoconferencing (UVC) System 5110 and 5115, and possibly Unified Videoconferencing System 3545 and 5230, Unified Videoconferencing 3527 Primary Rate Interface (PRI) Gateway, Unified Videoconferencing 3522 Basic Rate Interfaces (BRI) Gateway, and Unified Videoconferencing 3515 Multipoint Control Unit (MCU), allows remote authenticated administrators to execute arbitrary commands via the username field, related to a "shell command injection vulnerability," aka Bug ID CSCti54059.

Cisco Unified Videoconferencing (UVC) System 3545, 5110, 5115, and 5230; Unified Videoconferencing 3527 Primary Rate Interface (PRI) Gateway; Unified Videoconferencing 3522 Basic Rate Interfaces (BRI) Gateway; and Unified Videoconferencing 3515 Multipoint Control Unit (MCU) improperly use cookies for web-interface credentials, which allows remote attackers to obtain sensitive information by reading a (1) cleartext or (2) base64-encoded cleartext cookie, aka Bug ID CSCti54052.

The web interface in Cisco Unified Videoconferencing (UVC) System 3545, 5110, 5115, and 5230; Unified Videoconferencing 3527 Primary Rate Interface (PRI) Gateway; Unified Videoconferencing 3522 Basic Rate Interfaces (BRI) Gateway; and Unified Videoconferencing 3515 Multipoint Control Unit (MCU) uses predictable session IDs based on time values, which makes it easier for remote attackers to hijack sessions via a brute-force attack, aka Bug ID CSCti54048.
