| Título | IP-COM W30APv4.0 <= v1.0.0.11(1340) Stack-based Buffer Overflow |
|---|
| Descripción | An unauthenticated buffer overflow vulnerability exists in the `formWx3AuthorizeSet` function in any firmware of IP-COM W30APv4.0 <= v1.0.0.11(1340). In the handler function corresponding to `/goform/wx3auth`, the function accepts the `data` and `extend` parameters from a POST request via `websGetVar`. Subsequently, when the `extend` parameter is “pc”, and the `data` parameter (which is user-controllable) contains “data=” followed by non-empty content, the program directly uses `sprintf` to concatenate the unsanitized, unlength-checked external input into a fixed-size stack buffer, resulting in a stack-based buffer overflow vulnerability. |
