CVE-2021-32685
Improper Verification of Cryptographic Signature
描述
### 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) && `. ### For more information If you have any questions or comments about this advisory: * Open an issue in [github.com/TogaTech/tEnvoy](https://github.com/TogaTech/tEnvoy)
