Detailsinfo

A vulnerability was found in IBM Common Cryptographic Architecture and 4769 Developers Toolkit up to 7.5.51. It has been classified as problematic. This affects an unknown code block of the component ECDSA Signature Handler. The manipulation with an unknown input leads to a timing discrepancy vulnerability. CWE is classifying the issue as CWE-208. Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not. This is going to have an impact on confidentiality. The summary by CVE is:

IBM Common Cryptographic Architecture 7.0.0 through 7.5.51 could allow a remote attacker to obtain sensitive information during the creation of ECDSA signatures to perform a timing-based attack.

The advisory is shared at ibm.com. This vulnerability is uniquely identified as CVE-2024-22340 since 01/09/2024. The exploitability is told to be difficult. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

Upgrading eliminates this vulnerability.
