| 제목 | UTT HiPER 1200GW <=v2.5.3-170306 Buffer Overflow |
|---|
| 설명 | A serious buffer overflow vulnerability has been identified in the UTT Aggressive HiPER 1200GW router. The issue resides in the /goform/formTaskEdit endpoint, where insufficient bounds checking on user-supplied input allows an attacker to trigger a stack-based buffer overflow.
By sending a specially crafted HTTP request to /goform/formTaskEdit with an oversized parameter value, the attacker can overflow a fixed-size buffer located on the stack. The root cause lies in the insecure use of the strcpy function at the following code location: strcpy(InstPointByIndex + 20, src);. The destination buffer, InstPointByIndex, is of a fixed length, but the source data (src) is directly copied from user-controlled input without any length validation. When the input exceeds the buffer's capacity, data beyond the buffer boundary is overwritten, corrupting adjacent stack memory. |
