Name of the Vulnerable Software and Affected Versions Cisco Firepower Management Center (FMC) Software (affected versions not specified)

Description The issue is related to insufficient validation of user-supplied input by the web-based management interface, allowing an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack. This could enable the attacker to execute arbitrary script code in the context of the interface or access sensitive browser-based information. In some cases, it may also cause a temporary availability impact to portions of the FMC Dashboard.

Recommendations For Cisco Firepower Management Center (FMC) Software, consider restricting access to the web-based management interface until a fix is available. As a temporary workaround, avoid inserting crafted input into various data fields in the affected interface. Restrict the use of sensitive, browser-based information in the interface to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
