Summary

CallBackery for Perl before 0.60.1 has a path traversal flaw in its /doc route. The route passes the requested name to a POD search without validation, so the name can escape the module include path (CWE-22). An unauthenticated remote attacker can read the POD of any file the server process can read, because the route runs before any session check.

Description from the CNA

CallBackery versions before 0.60.1 for Perl let unauthenticated clients read the POD of any file via path traversal in the /doc route. Every CallBackery application mounts its documentation plugin at /doc, ahead of any session check. The route passes the requested name to Pod::Simple::Search->find without validation. find splits the name on "::" and joins the parts into a file path, so a name such as "..::..::..::etc::motd" escapes @INC. Any file the server process can read is reachable. Only POD is rendered, but a file with a POD directive and no "=cut" is POD to the end of the file.
