|---|
| 설명 | An unauthenticated or authenticated attacker (depending on device access and auth configuration) can craft a malicious POST request to /goform/formPdbUpConfig with a specially crafted policyNames parameter. The parameter is processed without proper validation and is ultimately used in a formatted system call (e.g. doSystem("xx%s", Var);), which can cause buffer overflow and/or command execution, resulting in device crash (DoS) or possible remote code execution under certain conditions.
The /goform/formPdbUpConfig endpoint accepts a policyNames parameter. When policyNames is not All and is not empty, the request is routed into a subroutine (identified in analysis as sub_447588) which performs additional processing. Within this path, the application constructs or forwards strings into a system-level call using a formatted string that incorporates the unvalidated policyNames value.
This dangerous usage (for example doSystem("xx%s", Var);) means that user-controlled input can influence the format string or the command executed by the shell. If the input exceeds expected length limits, a buffer overflow can occur. If shell interpretation is involved (string passed to system() or shell-piping utilities), classic command injection becomes possible. |
