Unauthenticated service interruption via unsanitized login input

Published Nov 18, 2025 · Updated Nov 18, 2025

The login handler fails to sanitize one POST parameter before backend processing; CERT.PL has not disclosed the parameter or query construction. No authentication is required, and command-injection probes also produce verbose errors that disclose internal infrastructure details; working SQL injection was not reproduced.
