Cisco Firepower Management Center Software Cross-Site Scripting Vulnerabilities
Priority: Medium
Advisory ID: cisco-sa-fmc-xss-yT8LNSeA
First Published: 2021 April 28 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCvw93272 CSCvw93276 CSCvw93282 CSCvw93513
CVE Names: CVE-2021-1455 CVE-2021-1456 CVE-2021-1457 CVE-2021-1458
CWEs: CWE-79
Summary
o Multiple vulnerabilities in the web-based management interface of Cisco
Firepower Management Center (FMC) Software could allow an unauthenticated,
remote attacker to conduct a cross-site scripting (XSS) attack against a
user of the interface.
These vulnerabilities are due to insufficient validation of user-supplied
input by the web-based management interface. An attacker could exploit
these vulnerabilities by persuading a user of the interface to click a
crafted link. A successful exploit could allow the attacker to execute
arbitrary script code in the context of the interface or access sensitive,
browser-based information.
Cisco has released software updates to address these vulnerabilities. There
are no workarounds that address these vulnerabilities.
