Unauthenticated code execution via stack buffer overflow
Published Sep 10, 2021 · Updated Sep 17, 2024
Stack buffer overflow in QNAP QUSBCam2 before 1.1.4 on QTS 4 or QuTS hero and before 2.0.1 on QTS 5 allows remote attackers to execute arbitrary code. QNAP identifies an out-of-bounds write to a stack buffer but has not disclosed the affected function, input field, or request format. Network reachability is sufficient and no authentication or user interaction is required; successful exploitation grants code execution in the NAS application's context.

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=unspecified <1.1.4 ( 2021/07/30 )
- Affected versionversion=unspecified <1.1.4 ( 2021/08/06 )
