When user downloads PGP or S/MIME keys/certificates, exported file has same name for private and public keys. Therefore its possible to mix them and to send private key to the third-party instead of public key. This issue affects ((OTRS)) Community Edition: 5.0.42 and prior versions, 6.0.27 and prior versions. OTRS: 7.0.16 and prior versions.

Weakness

The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
