| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
openssl encrypt versions prior to 1.4.9
Description
The software fails to re-derive and validate fingerprints when loading identities from the
identity.json file. This allows attackers to substitute legitimate public keys in identity stores with their own while maintaining the claimed fingerprint. Consequently, this enables silent key substitution, resulting in encryption using attacker-controlled keys while signature verification still appears valid.Recommendations
Update to version 1.4.9 or later.
