tag_summary = "Xerver is prone to multiple vulnerabilities including source code
disclosure, denial of service, security bypass, and directory-
traversal issues.

Successfully exploiting these issues may allow an attacker to disclose
sensitive information, bypass certain security-restrictions, perform
denial-of-service attacker or execute arbitrary binaries.

These issues affect Xerver versions up to and including 4.32.";
