Name of the Vulnerable Software and Affected Versions Cisco DPC3939 version dpc3939-P20-18-v303r20421746-170221a-CMCST

Description The issue allows local users with command access to read arbitrary files via UPnP access to the /var/IGD/ directory. This can be exploited by users who have gained command access as a result of previous exploitation.

Recommendations For Cisco DPC3939 version dpc3939-P20-18-v303r20421746-170221a-CMCST, consider restricting access to the /var/IGD/ directory to minimize the risk of exploitation. As a temporary workaround, disabling UPnP access until a patch is available can help mitigate the issue.
