CVE-2024-41766Network attack vector

Denial of service via complex regular expression

Published Jan 4, 2025 · Updated Jan 6, 2025

Inefficient regex processing in IBM Engineering Lifecycle Optimization - Publishing 7.0.2 and 7.0.3 allows remote attackers to interrupt service. A complex regular expression consumes excessive processing resources, but IBM has not disclosed the affected request handler, input field, or regex pattern. Network access without authentication or user interaction is sufficient, and the reported consequence is limited to service interruption.
