CVE-2024-4353· NVD / CVE Program· CNA ConcreteCMS

Stored XSS in Generate Board Name Input Field

Noroxi assessment

Priority: Monitor (action score 18/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.30% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No special conditions are required; it is repeatable.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS

Concrete CMS versions 9.0.0 through 9.3.2 are affected by a stored XSS vulnerability in the generate dashboard board instance functionality. The Name input field does not check the input sufficiently letting a rogue administrator have the capability to inject malicious JavaScript code. The Concrete CMS security team gave this vulnerability a CVSS v4 score of 4.6 with a vector of CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N. Concrete versions below 9 are not affected by this vulnerability.Thanks fhAnso 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).
