Resumen:	Yealink VoIP Phone devices are prone to multiple vulnerabilities.
Descripción:	Summary: Yealink VoIP Phone devices are prone to multiple vulnerabilities. Vulnerability Insight: - The 'user' account has a password of 'user' (hash = s7C9Cx.rLsWFA), the 'admin' account has a password of 'admin' (hash = uoCbM.VEiKQto), and the 'var' account has a password of 'var' (hash = jhl3iZAe./qXM). - The '/cgi-bin/cgiServer.exx' script not properly sanitizing user input, specifically encoded path traversal style attacks (e.g. '%2F') supplied via the 'page' parameter. - Contains a flaw in the /cgi-bin/cgiServer.exx script that is triggered when handling system calls. - The /cgi-bin/cgiServer.exx script not properly sanitizing user input, specifically absolute paths supplied via the 'command' parameter. Vulnerability Impact: Successful exploitation will allow remote attackers to trivially gain privileged access to the device, execute arbitrary commands and gain access to arbitrary files. Affected Software/OS: Yealink VoIP Phone SIP-T38G Solution: No known solution was made available for at least one year since the disclosure of this vulnerability.
