Detailsinfo

A vulnerability classified as problematic was found in Rhonabwy up to 1.1.13. This vulnerability affects the function strcmp of the component HMAC Handler. The manipulation with an unknown input leads to a signature verification vulnerability. The CWE definition for the vulnerability is CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. As an impact it is known to affect confidentiality. CVE summarizes:

In Rhonabwy through 1.1.13, HMAC signature verification uses a strcmp function that is vulnerable to side-channel attacks, because it stops the comparison when the first difference is spotted in the two signatures. (The fix uses gnutls_memcmp, which has constant-time execution.)

The weakness was released 02/11/2024 as f9fd9a1c77e48b514ebb3baf0360f87eef3d846e. The advisory is shared for download at github.com. This vulnerability was named CVE-2024-25714 since 02/11/2024. There are known technical details, but no exploit is available.
