CVE-2024-23680: CWE-347 Improper Verification of Cryptographic Signature
AWS Encryption SDK for Java versions 2.0.0 to 2.2.0 and less than 1.9.0 incorrectly validates some invalid ECDSA signatures.
AI Analysis
Technical Summary
The AWS Encryption SDK for Java versions 2.0.0 through 2.2.0 and versions prior to 1.9.0 contain a cryptographic signature validation flaw (CWE-347). Specifically, the SDK incorrectly validates some invalid ECDSA signatures, which may allow attackers to bypass signature verification checks. This vulnerability affects the integrity of cryptographic operations performed by the SDK. The issue has been assigned CVE-2024-23680 and has a CVSS 3.1 base score of 5.3 (medium severity). AWS operates this SDK as a cloud service and has made patches available to address the issue.
Potential Impact
The vulnerability allows improper validation of ECDSA signatures, potentially enabling attackers to bypass signature verification and compromise the integrity of cryptographic operations. There is no direct impact on confidentiality or availability reported. No known exploits are currently observed in the wild.
Mitigation Recommendations
A patch is available for this vulnerability. Since AWS Encryption SDK for Java is provided as a cloud service, AWS manages remediation server-side. Users should consult the AWS vendor advisory for confirmation and ensure their SDK versions are updated to a fixed release. No additional user action is required if using the managed cloud service.
