Summary
The affected software is the soap.cgi web interface component in several D-Link DIR-series home routers (DIR-880L, DIR-868L, DIR-865L, and DIR-860L) and their earlier firmware releases. The flaw lets a remote attacker run arbitrary operating system commands on the router by manipulating the service parameter, which could give them full control of the device.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.

Questions about CVE-2018-6530
What does this mean?
The LAN-side soap.cgi SOAP interface does not properly handle input, so it can run arbitrary operating system commands on the router. The impact includes starting a telnet server that gives an unauthenticated root shell.Source: github.com
Am I affected, and how do I check?
Affected are D-Link DIR-880L (RevA) firmware up to DIR-880L_REVA_FIRMWARE_PATCH_1.08B04, and related DIR-868L, DIR-865L and DIR-860L RevA firmware versions. Compare the installed firmware version against these listed versions.Source: github.com
What should I do about it?
Upgrade to firmware 1.08B06, which the advisory lists as the fixed version. The linked download is labeled BETA, so check the vendor's advisory for its current status.Source: github.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-09-08, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
