## Description

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>.
