CVE: CVE-2024-13176
A timing side-channel vulnerability exists in the ECDSA signature computation that could potentially allow an attacker to recover the private key. This vulnerability requires either local access to the signing application or a very fast network connection with low latency to measure the timing signal. The severity of this vulnerability is considered low, primarily affecting the NIST P-521 curve.
Details
| Severity | Base Score | CVE |
|---|---|---|
| MEDIUM | 4.1 | CVE-2024-13176 |
Exploitation
To exploit this vulnerability, an attacker must either have local access to the application performing ECDSA signature computations or be able to establish a very low-latency network connection to the target system. By measuring the timing of the signature operations, the attacker can potentially infer the private key used in the ECDSA process.
Affected Products
- OpenSSL FIPS modules 3.4, 3.3, 3.2, 3.1, and 3.0: These modules are affected due to the timing side-channel vulnerability in ECDSA signature computations.
Mitigation
To mitigate this vulnerability, it is recommended to limit access to the signing application and ensure that it is not exposed to untrusted networks. Additionally, implementing constant-time algorithms for ECDSA operations can help prevent timing attacks.
