Administrator reverse shell via unsafe Java deserialization
Published Jun 2, 2021 · Updated Aug 3, 2024
Deserialization of untrusted data in McAfee Database Security before 4.8.2 allows remote attackers to create an administrator reverse shell. The DBSec server processes a carefully constructed Java serialized object through its deserialization path, causing attacker-controlled command execution. No authentication or user interaction is required, but the attacker must have adjacent-network access to the server; exploitation grants administrator privileges.

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.
