CVE-2013-1595Public exploitNetwork attack vector

Unauthenticated code execution via oversized RTSP Authorization header

Published Jan 24, 2020 · Updated Aug 6, 2024

Buffer overflow in Vivotek PT7135 firmware 0300a and 0400a allows remote attackers to execute code or crash the camera via RTSP. The RTSP service fails to bound the Basic credential value in an Authorization header, letting repeated bytes overwrite the instruction pointer. No authentication or user interaction is required; a crafted DESCRIBE request to TCP port 554 can interrupt service or redirect execution.
