CVE-2026-79762: CWE-321: Use of Hard-coded Cryptographic Key in Termix-SSH Termix
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.
AI Analysis
Technical Summary
Termix-SSH, a web-based server management platform, has a vulnerability (CVE-2026-79762) involving the use of hard-coded cryptographic keys in versions >=1.7.0 <2.5.1. The keys that wrap OIDC and WebAuthn users' Data Encryption Keys are derived from default strings and a public userId salt because the secrets OIDC_SYSTEM_SECRET and WEBAUTHN_SYSTEM_SECRET are not configured by default. An attacker with offline access to the SQLite database can derive the wrapping key, recover each affected user's Data Encryption Key, and decrypt stored SSH passwords, private keys, and key passphrases. This vulnerability does not affect password-authenticated users. The issue is resolved in version 2.5.1.
Potential Impact
An attacker with read-only offline access to the Termix SQLite database can derive the cryptographic key used to protect OIDC and WebAuthn users' Data Encryption Keys. This enables decryption of sensitive SSH credentials including passwords, private keys, and key passphrases. The confidentiality of these credentials is compromised. There is no impact on integrity or availability. Password-authenticated users are not affected by this vulnerability.
Mitigation Recommendations
Upgrade Termix to version 2.5.1 or later, where this vulnerability is fixed. The fix involves proper configuration of OIDC_SYSTEM_SECRET and WEBAUTHN_SYSTEM_SECRET to avoid use of hard-coded default keys. No other mitigation is indicated by the vendor advisory.
