Description

Blue Coat SSL Visibility Appliance SV800, SV1800, SV2800, and SV3800, versions 3.6.x to 3.8.3, contain multiple vulnerabilities.

CWE-352: Cross-Site Request Forgery (CSRF) - CVE-2015-2852

Blue Coat SSL Visibility Appliance contains a cross-site request forgery (CSRF) vulnerability. An attacker can perform actions with the same permissions as a victim user, provided the victim has an active session and is induced to trigger the malicious request.

CWE-384: Session Fixation - CVE-2015-2853

A user's session ID is set prior to authentication, and is not invalidated or changed at the time of authentication. An attacker capable of obtaining or setting a session ID can hijack a victim user's session.

CWE-20: Improper Input Validation - CVE-2015-2854

Blue Coat SSL Visibility Appliance does not enforce same origin policy in X-Frame-Options response headers. An attacker can conduct clickjacking attacks via a crafted web page.

CWE-200: Information Exposure - CVE-2015-2855

Sensitive cookies do not have either the Secure or HttpOnly flags set. An attacker capable of sniffing network traffic can intercept or manipulate a victim user's session ID.

The CVSS score reflects CVE-2015-2852. For more information about these issues, see FishNet Security's write-up.
