A stack-based buffer overflow vulnerability exists in the touchlist_sync.cgi touchlistsync() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary code execution. An attacker can send an HTTP request to trigger this vulnerability.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
