The Symantec Advanced Secure Gateway (ASG) 6.6, ASG 6.7 (prior to 6.7.2.1), ProxySG 6.5 (prior to 6.5.10.6), ProxySG 6.6, and ProxySG 6.7 (prior to 6.7.2.1) management console is susceptible to a reflected XSS vulnerability. A remote attacker can use a crafted management console URL in a phishing attack to inject arbitrary JavaScript code into the management console web client application. This is a separate vulnerability from CVE-2016-10256.

Blue Coat Advanced Secure Gateway 6.6, CacheFlow 3.4, ProxySG 6.5 and 6.6 allows remote attackers to bypass blocked requests, user authentication, and payload scanning.

The Symantec Advanced Secure Gateway (ASG) 6.6 prior to 6.6.5.8, ProxySG 6.5 prior 6.5.10.6, ProxySG 6.6 prior to 6.6.5.8, and ProxySG 6.7 prior to 6.7.1.2 management consoles do not, under certain circumstances, correctly authorize administrator users. A malicious administrator with read-only access can exploit this vulnerability to access management console functionality that requires read-write access privileges.

Symantec Advanced Secure Gateway (ASG) 6.6, ASG 6.7 prior to 6.7.2.1, ProxySG 6.5 prior to 6.5.10.6, ProxySG 6.6, and ProxySG 6.7 prior to 6.7.2.1 are susceptible to an open redirection vulnerability. A remote attacker can use a crafted management console URL in a phishing attack to redirect the target user to a malicious web site.

Symantec Advanced Secure Gateway (ASG) 6.6 prior to 6.6.5.13, ASG 6.7 prior to 6.7.3.1, ProxySG 6.5 prior to 6.5.10.6, ProxySG 6.6 prior to 6.6.5.13, and ProxySG 6.7 prior to 6.7.3.1 are susceptible to an information disclosure vulnerability. An attacker with local access to the client host of an authenticated administrator user can, under certain circumstances, obtain sensitive authentication credential information.

Open redirect vulnerability in Blue Coat ProxySG 6.5 before 6.5.8.8 and 6.6 and Advanced Secure Gateway (ASG) 6.6 might allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a base64-encoded URL in conjunction with a "clear text" one in a coaching page, as demonstrated by "http://www.%humbug-URL%.local/bluecoat-splash-API?%BASE64-URL%."

The default configuration of SGOS in Blue Coat ProxySG before 6.2.16.5, 6.5 before 6.5.7.1, and 6.6 before 6.6.2.1 forwards authentication challenges from upstream origin content servers (OCS) when used in an explicit proxy deployment, which makes it easier for remote attackers to obtain sensitive information via a 407 (aka Proxy Authentication Required) HTTP status code, as demonstrated when using NTLM authentication.

The caching feature in SGOS in Blue Coat ProxySG 5.5 through 5.5.11.3, 6.1 through 6.1.6.3, 6.2 through 6.2.15.3, 6.4 through 6.4.6.1, and 6.3 and 6.5 before 6.5.4 allows remote authenticated users to bypass intended access restrictions during a time window after account deletion or modification by leveraging knowledge of previously valid credentials.

Blue Coat ProxySG before 6.2.14.1, 6.3.x, 6.4.x, and 6.5 before 6.5.2 allows remote attackers to cause a denial of service (memory consumption and dropped connections) via a recursive href in an HTML page, which triggers a large number of HTTP RW pipeline pre-fetch requests.

Cross-site scripting (XSS) vulnerability in the Java Management Console in Blue Coat ProxySG before SGOS 4.3.4.1, 5.x before SGOS 5.4.5.1, 5.5 before SGOS 5.5.4.1, and 6.x before SGOS 6.1.1.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
