v11.0 and XG (12.0)*
OfficeScan protects enterprise networks from malware, network viruses, web-based threats, spyware, and mixed threat attacks.
An integrated solution, OfficeScan consists of the OfficeScan agent program that resides at the endpoint and a server program that
manages all agents. The OfficeScan agent guards the endpoint and reports its security status to the server. The server, through the
web-based management console, makes it easy to set coordinated security policies and deploy updates to every agent.
Man-in-the-Middle (MITM) Remote Code Execution
MITM vector exists as the CURL request used by Send() function in "HttpTalk.php" has both CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST set to false.
CURLOPT_SSL_VERIFYPEER checks if remote certificate is valid and that you trust was issued by a CA you trust and it's genuine.
CURLOPT_SSL_VERIFYHOST checks that the cert was issued to the entity you want to talk to...
Vulnerable code snippet...
curl_setopt($this->_objcurlHandle, CURLOPT_HEADER, true);
curl_setopt($this->_objcurlHandle, CURLOPT_SSL_VERIFYHOST, 0); <=================== HERE
curl_setopt($this->_objcurlHandle, CURLOPT_SSL_VERIFYPEER, 0); <==================== THERE
