D-Link has issued a firmware hotfix to address multiple vulnerabilities in the DIR-3040 AC3000-based wireless internet router.

Following successful exploitation, they can let attackers execute arbitrary code on unpatched routers, gain access to sensitive information or crash the routers after triggering a denial of service state.

The DIR-3040 security flaws discovered and reported by Cisco Talos security researcher Dave McDaniel include hardcoded passwords, command injection, and information disclosure bugs.
D-Link has resolved the bugs found in firmware version 1.13B03 and has issued a firmware hotfix for all affected customers on July 15, 2021, available for download here.
