CVE-2024-26289Network attack vector

Unauthenticated code execution via unsafe deserialization

Published May 27, 2024 · Updated Aug 2, 2024

Deserialization in PMB Services PMB allows remote attackers to execute malicious code over the network through crafted serialized data. ENISA and PMB Services have not published the affected component, entry point, serialized object format, or exact deserialization operation. Default installations are exposed without authentication or user interaction, and successful exploitation permits reading or altering application data and interrupting the service.
