Detailsinfo

A vulnerability classified as problematic has been found in Termix-SSH Termix up to 2.5.0. This affects an unknown code block of the file src/backend/utils/user-crypto.ts of the component User Crypto. The manipulation with an unknown input leads to a risky encryption vulnerability. CWE is classifying the issue as CWE-327. The product uses a broken or risky cryptographic algorithm or protocol. This is going to have an impact on confidentiality. The summary by CVE is:

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 1.7.0 until 2.5.1, Termix derives the keys that wrap OIDC and WebAuthn users' Data Encryption Keys from committed default strings and the public userId salt in src/backend/utils/user-crypto.ts. Because OIDC_SYSTEM_SECRET and WEBAUTHN_SYSTEM_SECRET are not configured by the project's default deployment artifacts, an attacker with an offline SQLite database copy can derive the wrapping key, recover each affected user's DEK, and decrypt stored SSH passwords, private keys, and key passphrases. Password-authenticated users are not affected by this specific key derivation path. This issue is fixed in version 2.5.1.
