Unauthenticated information disclosure via cleartext files

Published Sep 26, 2025 · Updated Sep 26, 2025

Cleartext storage in IBM Aspera HTTP Gateway 2.0.0 through 2.3.1 allows remote attackers to read sensitive information. IBM states that easily obtainable files contain the cleartext data but has not disclosed the files, data elements, or operation that creates them. Unauthenticated network access is sufficient, and the documented consequence is disclosure without data modification or service interruption.
