CVE-2024-45167

Estado: AnalizadaCrítica (9.8)—

An issue was discovered in UCI IDOL 2 (aka uciIDOL or IDOL2) through 2.12. Due to improper input validation, improper deserialization, and improper restriction of operations within the bounds of a memory buffer, IDOL2 is vulnerable to Denial-of-Service (DoS) attacks and possibly remote code execution. A certain XmlMessage document causes 100% CPU consumption.
