Description

A heap-based buffer overflow vulnerability exists in a Network management service of AOS-8 and AOS-10 that could allow an unauthenticated remote attacker to achieve remote code execution. Successful exploitation could allow an unauthenticated attacker to execute arbitrary code as a privileged user on the underlying operating system, potentially leading to a system compromise. Exploitation may also result in a denial-of-service (DoS) condition affecting the impacted system process.
