A vulnerability has been found in D-Link DI-8100 16.07.26A1. Affected by this issue is the function file_exten_asp of the file file_exten.asp of the component File Extension Handler. The manipulation of the argument Name leads to buffer overflow. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used.
Casky was already ahead
This CVE exploits attack patterns that Casky's 255matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
CVE-2026-7247 is a remote buffer overflow vulnerability affecting D-Link DI-8100 routers in firmware version 16.07.26A1. The flaw exists in the file_exten.asp component's file extension handler function, where unsanitized input to the "Name" parameter allows attackers to overflow a buffer and execute arbitrary code. This vulnerability is particularly critical because D-Link routers are widely deployed in small business and enterprise network perimeters, making them attractive targets for initial compromise. With a CVSS score of 7.2 and public exploit availability, this represents an active threat to organizations running vulnerable firmware versions.
Casky's Claude-powered detection engine maps this vulnerability to MITRE ATT&CK techniques T1203 (Exploitation for Client Execution) and T1499 (Endpoint Denial of Service), identifying malicious traffic patterns that attempt buffer overflow attacks against the file_exten.asp endpoint. Practitioners using Casky would observe security findings flagging: unexpected large parameter values in HTTP requests to file_exten.asp, anomalous Name argument payloads exceeding expected string lengths, POST requests with encoded shellcode patterns, and potential process execution or service crashes following exploitation attempts. The platform's 754 mapped security skills enable detection of the attack chain from reconnaissance of the vulnerable service through exploitation and post-compromise activities, providing defenders with comprehensive visibility into attacks leveraging this CVE.
