CVE-2024-4350
Concrete CMS versions 9.0.0 to 9.3.2 and below 8.5.18 are vulnerable to Stored XSS in RSS Displayer when user input is stored and later embedded into responses.
Does this matter?
Lower severity and a low EPSS score (0.49%). Track it; it rarely justifies an emergency change on its own.
Description
Concrete CMS versions 9.0.0 to 9.3.2 and below 8.5.18 are vulnerable to Stored XSS in RSS Displayer when user input is stored and later embedded into responses. A rogue administrator could inject malicious code into fields due to insufficient input validation. The Concrete CMS security team gave this vulnerability a CVSS v4 score of 5.1 with vector https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N Thanks, m3dium for reporting. (CNA updated this risk rank on 17 Jan 2025 by lowering the AC based on CVSS 4.0 documentation that access privileges should not be considered for AC)
