Authenticated code execution via unsafe deserialization
Published Nov 22, 2024 · Updated Nov 25, 2024
Deserialization of untrusted data in Allegra before 7.5.2 allows remote authenticated users to execute code as LOCAL SERVICE. The loadFieldMatch method deserializes user-controlled data without proper validation, enabling attacker-supplied objects to trigger code execution. Exploitation requires high-privilege authentication over the network, and successful code runs with the service account's permissions.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=7.5.1.9
- Affected versionversion=7.5.1.9 <7.5.2
- Affected versionversion=* <7.5.2
