Modified

Severity

9.8 (Critical) CVSS_V3 - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H CVSS Calculator

Summary

Improper Verification of Cryptographic Signature

Details

Impact

The verifyWithMessage method of tEnvoyNaClSigningKey always returns true for any signature of a SHA-512 hash matching the SHA-512 hash of the message even if the signature is invalid.

Patches

Upgrade to v7.0.3 immediately to resolve this issue. Since the vulnerability lies within the verification method, the previous signatures are still valid. We highly recommend reverifying any signatures that were previously verified with the vulnerable verifyWithMessage method.

Workarounds

In tenvoy.js under the verifyWithMessage method definition within the tEnvoyNaClSigningKey class, ensure that the return statement call to this.verify ends in .verified. For example, the return statement should start with return this.verify(signed, password).verified && instead of return this.verify(signed, password) && .
