Cisco Web Security Appliance Stored Cross-Site Scripting Vulnerability

<p>A vulnerability in the web-based management interface of Cisco&nbsp;AsyncOS Software for Cisco&nbsp;Web Security Appliance (WSA) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface of an affected device.&nbsp;</p>
<p>The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious data into a specific data field in an affected interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface.</p>
<p>Cisco&nbsp;has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.</p>
