CVE-2015-10149
Dancer versions before 1.3400 for Perl pass unvalidated session ids from the session cookie to the session engine
Description
Dancer versions before 1.3400 for Perl pass unvalidated session ids from the session cookie to the session engine. read_session_id returns the cookie value as the session id without checking its characters, and Dancer hands it to the session engine to load the session. A remote attacker may cause path traversal or injection in a session engine that uses the id in a file path, cache command or query without checking it.
