CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
A remote PHP code execution vulnerability exists in InstantCMS version 1.6 and earlier due to unsafe use of eval() within the search view handler. Specifically, user-supplied input passed via the look parameter is concatenated into a PHP expression and executed without proper sanitation. A remote attacker can exploit this flaw by sending a crafted HTTP GET request with a base64-encoded payload in the Cmd header, resulting in arbitrary PHP code execution within the context of the web server.
