| 제목 | D-Link DIR895LA1_102b07 A1_102b07 Stack-based Buffer Overflow |
|---|
| 설명 | A stack-based buffer overflow vulnerability exists in the `udhcpcd` DHCP server of D-Link DIR-895L. The issue is located in the TR-111 parsing routine for DHCP vendor-specific option 125, where attacker-controlled suboption data is copied into fixed-size stack buffers using `strcpy()` even though the source data is length-delimited DHCP option content rather than a NUL-terminated C string.
Because the vulnerable path is reachable from unauthenticated DHCP client traffic on the local network, a remote attacker on the LAN can trigger memory corruption by sending a crafted DHCP message containing a malicious option 125 payload. |
