It meets PCI Compliance and also provides E-Commerce Security, IIS and Apache Security, Cloud Security and more.     Vulnerability Type: ================================= Cross Site Request Forgery - CSRF     CVE Reference: ============== N/A     Vulnerability Details: ===================== Dotdefender firewall (WAF) is vulnerable to cross site request forgery, this allows attackers to make HTTP requests via the victims browser to the dotdefender management server on behalf of the victim if the victim is logged in and visits a malicious web page or clicks an infected link. Result can be modifying or disabling various firewall patterns, User-Defined Rule settings and global event logging etc...     HTTP requests sent to Dotdefender to enable or disable user-Defined rule settings are base64 encoded using SOAP protocol. Sending the below base64 value for example disables a Dotdefender firewall setting.   PGVuYWJsZWQ+ZmFsc2U8L2VuYWJsZWQ+ <enabled>false</enabled>     Tested successfully on Windows & Linux:   dotDefender Version:5.00.12865 Web Server Type:Microsoft-IIS Server Operating System:Windows Web Server Version: 7.5 Firefox web browser     dotDefender Version: 5.13-13282 Web Server Type: Apache Server Operating System: Linux     Exploit code(s): ===============   Example to send requests to disable firewall rule settings that defends against SQL injection.
