CVE-2022-31209Network attack vector

Memory corruption via unchecked next_url copy

Published Jul 17, 2022 · Updated Aug 3, 2024

Buffer overflow in Infiray IRAY-A8Z3 firmware 1.0.957 allows remote attackers to corrupt memory via a long next_url parameter. A firmware handler allocates a 64-byte buffer and uses strcpy() to copy the attacker-controlled next_url value without checking its length. The issue was identified only through firmware analysis and was not exercised on a live camera, so code execution and service disruption remain unverified.
