A vulnerability was found in Cisco FirePOWER Management Center (Firewall Software) (the affected version is unknown). It has been classified as problematic. Affected is an unknown code of the component Web-based Management Interface. The manipulation with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. CVE summarizes:

Multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) Software 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. These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit these vulnerabilities by inserting crafted input into various data fields in an affected interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface, or access sensitive, browser-based information. In some cases, it is also possible to cause a temporary availability impact to portions of the FMC Dashboard.

The weakness was released 11/16/2022 as cisco-sa-fmc-xss-LATZYzxs. The advisory is shared for download at tools.cisco.com. This vulnerability is traded as CVE-2022-20843 since 11/02/2021. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1059.007.
