Known exploited

CISA added this to the Known Exploited Vulnerabilities Catalog on 8 Sept 2022 and links it to ransomware activity. US federal agencies had to remediate by 29 Sept 2022, a deadline that has passed.

Required action. The vendor D-Link published an advisory stating the fix under CVE-2018-20114 properly patches KEV entry CVE-2018-6530. If the device is still supported, apply updates per vendor instructions. If the affected device has since entered its end-of-life, it should be disconnected if still in use.

Description

OS command injection vulnerability in soap.cgi (soapcgi_main in cgibin) in D-Link DIR-880L DIR-880L_REVA_FIRMWARE_PATCH_1.08B04 and previous versions, DIR-868L DIR868LA1_FW112b04 and previous versions, DIR-65L DIR-865L_REVA_FIRMWARE_PATCH_1.08.B01 and previous versions, and DIR-860L DIR860LA1_FW110b04 and previous versions allows remote attackers to execute arbitrary OS commands via the service parameter.

The kind is read from NVD's tags where present and from the shape of the URL otherwise, so treat it as a hint.
