Basic Analysis and Security Engine (BASE) (http://base.secureideas.net/) One more security product with lame bugs... Let's look at Kevin's authentication code, for example in base_main.php (all pages vulnerable): [...] 64 // Check role out and redirect if needed -- Kevin 65 $roleneeded = 10000; 66 $BUser = new BaseUser(); 67 //if (($Use_Auth_System == 1) && ($BUser->hasRole($roleneeded) == 0)) 68 if ($Use_Auth_System == 1) 69 { 70 if ($BUser->hasRole($roleneeded) == 0) 71 { 72 header("Location: $BASE_urlpath/index.php"); 73 } 74 } [...] Where is bug? Yes, your browser will redirect after received location header, but what if not? ;-) Test with curl. This is not first authentication issue in BASE, putting at risk users which use BASE authentication feature. Google shows up many installations protected by this feature. All BASE versions with authentication are vulnerable. ACID is not vulnerable, since it doesn't has such feature. BASE+ fork has fixed this issue year ago. Use your web server authentication or BASE+, which sucks less. _______________________________________________ Full-Disclosure - We believe in it.
