Authentication bypass via absolute-path database overwrite
Published Aug 26, 2024 · Updated Aug 26, 2024
Arbitrary file write in Malwared BYOB 2.0's exfiltration endpoint allows remote attackers to overwrite its SQLite database via HTTP. The unauthenticated file_add route passes an attacker-controlled filename as the final os.path.join component, then writes decoded request data to the resulting path. An absolute filename can therefore replace database.db with attacker-supplied records and enable administrative registration; command execution requires chaining a separate flaw.

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.
