AL-Enterprise OmniVista 4760 any version

An issue was discovered on Alcatel-Lucent OmniVista 4760 devices. A remote unauthenticated attacker can chain a directory traversal (which helps to bypass authentication) with an insecure file upload to achieve Remote Code Execution as SYSTEM. The directory traversal is in the __construct() whereas the insecure file upload is in SetSkinImages().

An issue was discovered on Alcatel-Lucent OmniVista 4760 devices, and 8770 devices before 4.1.2. An incorrect web server configuration allows a remote unauthenticated attacker to retrieve the content of its own session files. Every session file contains the administrative LDAP credentials encoded in a reversible format. Sessions are stored in /sessions/sess_<sessionid>.
