An information disclosure vulnerability in SWG in versions 12.x prior to 12.2.10 and 11.x prior to 11.2.24 allows information stored in a customizable block page to be disclosed to third-party websites due to Same Origin Policy Bypass of browsers in certain scenarios. The risk is low, because other recommended default security policies such as URL categorization and GTI are in place in most policies to block access to uncategorized/high risk websites. Any information disclosed depends on how the customers have customized the block pages.

A password management vulnerability in Skyhigh Secure Web Gateway (SWG) in main releases 11.x prior to 11.2.14, 10.x prior to 10.2.25 and controlled release 12.x prior to 12.2.1, allows some authentication information stored in configuration files to be extracted through SWG REST API. This was possible due to SWG storing the password in plain text in some configuration files.

An authentication bypass vulnerability in Skyhigh SWG in main releases 10.x prior to 10.2.12, 9.x prior to 9.2.23, 8.x prior to 8.2.28, and controlled release 11.x prior to 11.2.1 allows a remote attacker to bypass authentication into the administration User Interface. This is possible because of SWG incorrectly whitelisting authentication bypass methods and using a weak crypto password. This can lead to the attacker logging into the SWG admin interface, without valid credentials, as the super user with complete control over the SWG.
