Discussion

Symantec Web Security Multiple Denial of Service And Cross-Site Scripting Vulnerabilities

Symantec Web Security is prone to a denial-of-service vulnerability and multiple cross-site scripting vulnerabilities. Under certain circumstances, the application will fail to effectively block malicious URIs used in cross-site scripting attacks.

An attacker can exploit these issues to slow system processes, causing denial-of-service conditions or to have arbitrary script code execute in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

Symantec Web Security versions prior to 3.0.1.85 are vulnerable.

Exploit / POC
