CVE-2023-45382Network attack vector

Unauthenticated file disclosure via unsanitized download path

Published Nov 17, 2023 · Updated Aug 12, 2024

Path traversal in Common-Services SoNice Retour 2.1.0 and earlier allows remote attackers to read server files without authentication. The downloadLabel.php action uses the attacker-controlled file request parameter directly as a path rather than reducing it to a basename or enforcing an allowed directory. A guest can invoke the exposed download function and retrieve arbitrary readable files, including personal information and application secrets.
