Memory disclosure or crash via out-of-bounds read
Published Dec 20, 2021 · Updated Aug 4, 2024
Out-of-bounds read in Fuji Electric V-Server Lite and Tellus Lite V-Simulator before 4.0.12.0 allows attackers to read memory or crash. CISA identifies neither the malformed input nor the parser or routine that reads past its intended buffer boundary. Exploitation is not remote and requires a local attack path plus user interaction, with sensitive-memory disclosure or an application crash as the bounded outcomes.

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.
