CVE-2024-7394 — Concrete CMS versions 9 through 9.3.2 and below 8.5.18 are vulnerable to Stored XSS in getAttributeSetName()

Medium CVSS 4.8

Concrete CMS versions 9 through 9.3.2 and below 8.5.18 are vulnerable to Stored XSS in getAttributeSetName(). A rogue administrator could inject malicious code. The Concrete CMS team gave this a CVSS v4.0 rank of 4.6 with vector https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N. Thanks, m3dium for reporting. (CNA updated this risk rank on 20 Jan 2025 by lowering the AC based on CVSS 4.0 documentation that access privileges should not be considered for AC)

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
