CVE-2024-51466Network attack vector

Data exposure and server crash via EL injection

Published Dec 20, 2024 · Updated Dec 20, 2024

EL injection in IBM Cognos Analytics 11.2.0 through 11.2.4 FP4 and 12.0.0 through 12.0.4 allows remote attackers to expose data or crash the server. IBM has not published the affected endpoint or the operation that evaluates attacker-controlled EL syntax. No authentication or user interaction is required, and successful exploitation can disclose sensitive information, exhaust memory, or interrupt service by crashing the server.
