This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The binary orthrus in /sbin folder of the device handles all the UPnP connections received by the device. It seems that the binary performs a sprintf operation at address 0x0000A3E4 with the value in the command line parameter "-f" and stores it on the stack. Since there is no length check, this results in corrupting the registers for the function sub_A098 which results in memory corruption.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
