CVE-2022-51025

Penta Security WAPPLES 4.0.54.1, 5.0, and 6.0 contains a path traversal vulnerability that allows authenticated attackers to download arbitrary files via the name parameter of /webapi/file/transfer. Attackers can send GET requests with type=db_backup and ../ sequences in name to read files like /etc/passwd, and a hardcoded systemi account makes authentication effectively trivial. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.
