Cisco Secure Web Appliance XSS (cisco-sa-esa-sma-wsa-xss-bgG5WHOD)

medium Nessus Plugin ID 197881


The remote device is missing a vendor-supplied security patch.


A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Secure Web Appliance could allow an authenticated, remote attacker to conduct an XSS attack against a user of the interface. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
