| Title | D-Link DWR-M920 V1.1.5 Buffer Overflow |
|---|
| Description | [cite_start]During a security review of the application, a critical buffer overflow vulnerability was discovered in the “/boafrm/formTracerouteDiagnosticRun” endpoint. [cite_start]The vulnerability is located within the sub_41E080 function, which calls the sub_41DF84 function. [cite_start]This function uses the sprintf function to parse the “host” parameter from an incoming request. [cite_start]Due to the lack of proper bounds checking on the input, a malicious actor can supply an oversized "host" parameter to overwrite the program's stack. [cite_start]This can lead to application crashes, memory corruption, and potentially allow for arbitrary code execution on the server. |
