All versions of ProxySG prior to 6.1.2 are vulnerable.
Malicious scripts are commonly encoded in web pages and run without a user's knowledge. ProxySG can be configured to supplement virus scanning of Web content by detecting and removing the HTML tags that launch active content such as Java applets or scripts. In addition the removed content can be replaced with predefined material, also called active content transformation.
- Anything within the <script></script> tags.
Vulnerable SGOS versions only detect these tags and attributes encoded in ASCII. Tags and attributes encoded in other formats will elude detection.
Malicious active content is difficult to distinguish from legitimate active content. ProxySG active content transformation and removal is designed to supplement WebPulse, virus scanners, and browser protections that detect and prevent malicious active content. Customers are encouraged to employ multiple layers of protection to achieve the best results.
