Title: eSafe Gateway Unicode Script-filtering Bypass Vulnerability
Severity: MODERATE
Description:
eSafe Gateway is a security utility used for filtering internet content on web-servers.
An html file may be crafted to bypass the script-filtering feature offered by eSafe Gateway. The html filtering mechanism does not detect unicode-format <SCRIPT> tags.
If an encoded <SCRIPT> command is included in an HTML document visited from the target site, eSafe will fail to detect it. The user's browser, however, will properly interpret it and the script will execute normally.
Affected Products:
- Aladdin Knowledge Systems eSafe Gateway 3.0.0
