| 제목 | UTT HiPER 1250GW <=v2.5.3-170306 Buffer Overflow |
|---|
| 설명 | A serious buffer overflow vulnerability has been identified in the UTT HiPER 1250GW router. The vulnerability exists in the /goform/formFireWall endpoint, where improper input validation allows an attacker to trigger a stack-based buffer overflow by manipulating the Profile parameter.
By sending a specially crafted HTTP request to /goform/formFireWall containing an oversized value in the Profile parameter, an attacker can overflow a fixed-size buffer allocated on the stack. The root cause of this vulnerability is the unsafe use of the strcpy function at the following code location: strcpy((char *)(InstPointByIndex + 216), src_1);. Here, the destination buffer is offset 216 bytes from InstPointByIndex and has a fixed allocation, yet the source string src_1 is populated directly from the attacker-controlled Profile parameter without any boundary checks. When the supplied input exceeds the size of the destination buffer, excess data overwrites adjacent memory on the stack, including critical control data. |
