CVE-2024-3967

Remote code execution via email configuration deserialization

Published May 15, 2024 · Updated Aug 1, 2024

Unsafe deserialization in OpenText iManager 3.0.0 through 3.2.6.0300 allows remote authenticated users to execute arbitrary code. The email configuration handler deserializes attacker-controlled Java object data without restricting object types, enabling gadget-triggered code execution. Exploitation requires adjacent-network access, low privileges, and user interaction; successful gadget execution runs code in the iManager server context.
