Description
HTTP::Session versions before 0.43 for Perl allow memcached command injection via unfiltered session ids in HTTP::Session::Store::Memcached.

The session id from the client's cookie reaches memcached unchanged as the cache key.

A CR and LF in the session id end the cache command early, and the server reads the bytes after them as further commands.
