DescriptionTermix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 1.7.0 until 2.5.1, the POST /credentials/:id/deploy-to-host endpoint resolves credential and target-host records from attacker-controlled credentialId and targetHostId integer values without checking that either record belongs to the requesting user. In src/backend/database/routes/credentials.ts, differential errors reveal whether credential and host records exist and disclose each record's authType value. Properly encrypted passwords and keys are not disclosed, but a key-authenticated victim host can receive an outbound SSH connection attempt using the attacker's public key. This issue is fixed in version 2.5.1.
