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
AWS Encryption SDK for Java versions 2.0.0 to 2.2.0 and versions less than 1.9.0 contain a CWE-347 vulnerability due to improper verification of some invalid ECDSA cryptographic signatures. This flaw could allow an attacker to bypass signature validation, potentially impacting data integrity. The vulnerability is rated medium severity (CVSS 5.3) with network attack vector, low complexity, no privileges required, and no user interaction needed. AWS operates this as a cloud service and manages patching on the server side.
Potential Impact
The vulnerability allows incorrect validation of certain invalid ECDSA signatures, which may lead to integrity violations in cryptographic operations performed by the AWS Encryption SDK for Java. There is no direct confidentiality or availability impact reported. No known exploits are currently observed in the wild.
Mitigation Recommendations
AWS manages remediation for this cloud-hosted service and has a patch available. Users should verify with the official AWS advisory for the current patch status and ensure their environments are updated accordingly. No additional user action is required beyond applying the official patch or update provided by AWS.
