CVE-2023-27989

Name of the Vulnerable Software and Affected Versions Zyxel NR7101 versions prior to V1.00(ABUV.8)C0

Description The issue is related to a buffer overflow in the CGI interface of the Zyxel NR7101 firmware. This could allow a remote attacker to cause denial of service (DoS) conditions by sending a crafted HTTP request to a vulnerable device. The exploitation of this issue may result in a denial of service.

Recommendations For versions prior to V1.00(ABUV.8)C0, update to version V1.00(ABUV.8)C0 or later to resolve the issue. As a temporary workaround, consider restricting access to the CGI interface to minimize the risk of exploitation.
