This buffer overflow vulnerability affects the web management interface of D-Link DI-8100, a widely deployed entry-level multi-WAN router for small businesses. The flaw exists in the /url_member.asp file, where improper input validation of the `Name` request argument allows malicious actors to trigger buffer overflow. Remote attackers can exploit this flaw to execute arbitrary code or crash the affected device.
Remediation
Apply the latest official firmware update from D-Link for DI-8100 devices if a patched version is available. Restrict access to the web management interface to only trusted internal IP addresses. Disable remote management functionality if it is not required for operations.
