CVE-2025-59058 (GCVE-0-2025-59058)

Vulnerability from cvelistv5 – Published: 2025-09-12 13:10 – Updated: 2025-09-12 13:45

Title

httpsig-rs's HMAC verification is vulnerable to timing attack

Summary

httpsig-rs is a Rust implementation of IETF RFC 9421 http message signatures. Prior to version 0.0.19, the HMAC signature comparison is not timing-safe. This makes anyone who uses HS256 signature verification vulnerable to a timing attack that allows the attacker to forge a signature. Version 0.0.19 fixes the issue.

Severity

5.9 (Medium)

GHSA-Q7PG-9PR4-MRP2

Vulnerability from github – Published: 2025-09-12 21:11 – Updated: 2025-09-12 21:11

Summary

httpsig-rs: HMAC verification is vulnerable to timing attack

Details

Summary

HMAC signature comparison is not timing-safe and is vulnerable to timing attacks.

Details

SharedKey::sign() returns a Vec<u8> which has a non-constant-time equality implementation.

Hmac::finalize() returns a constant-time wrapper (CtOutput) which was discarded. Alternatively, Hmac has a constant-time verify() method.

The problem reported here is due to the following lines in SharedKey::sign() of the previous code:

let mut mac = HmacSha256::new_from_slice(key).unwrap();
mac.update(data);
Ok(mac.finalize().into_bytes().to_vec())

and the merged update changes the third line to directly verify with verify_slice.

Impact

Anyone who uses HS256 signature verification is vulnerably to Timing Attack that allows the attacker to forge a signature.

Severity

5.9 (Medium)
