Specifically, a stack-based buffer overflow can be triggered in the \u003ccode\u003eformWlEncrypt\u003c/code\u003e function located within the \u003ccode\u003e/goform/formWlEncrypt\u003c/code\u003e file. This vulnerability allows a remote attacker to inject arbitrary code by sending a specially crafted request to the router, manipulating the \u003ccode\u003ewebpage\u003c/code\u003e argument. This exploit has been publicly disclosed, increasing the risk of widespread exploitation. Successful exploitation grants the attacker complete control over the device. The vendor was notified, but no response has been received.
