CVE-2021-1238 Detail

Description

Multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface of an affected system. The vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. 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 affected interface or access sensitive, browser-based information.

CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  4.8 MEDIUM
Vector:  CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N

Nist CVSS score does not match with CNA score
CNA:  Cisco Systems, Inc.
Base Score:  4.8 MEDIUM
Vector:  CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
