Description
phpIPAM through 1.8.3 contains a missing authorization vulnerability that allows authenticated low-privilege users to view restricted subnets and addresses because customer, location and NAT pages skip Subnets::check_permission. Attackers can open customer objects.php, single-location.php or nat_details.php to read IP addresses, CIDRs, hostnames and MAC addresses from sections they cannot access.
