CVE-2023-41752Network attack vector

AWS access key ID disclosure through s3_auth hashing

Published Oct 17, 2023 · Updated Jun 12, 2025

Information disclosure in Apache Traffic Server 8.0.0 through 8.1.8 and 9.0.0 through 9.2.2 allows remote attackers to read access key IDs. The s3_auth plugin exposes the configured AWSAccessKeyId during request-signature hash calculation, but Apache has not published the exact faulty operation. The issue is reachable only when s3_auth protects an Amazon S3 origin, and the documented impact is limited to the access key identifier rather than the secret key.
