CVE intelligence and bounded remediation

CVE-2023-31868 — Sage X3 version 12.14.0.50-0 is vulnerable to Cross Site Scripting (XSS)

Medium CVSS 5.4

Sage X3 version 12.14.0.50-0 is vulnerable to Cross Site Scripting (XSS). Some parts of the Web application are dynamically built using user's inputs. Yet, those inputs are not verified nor filtered by the application, so they mathed the expected format. Therefore, when HTML/JavaScript code is injected into those fields, this code will be saved by the application and executed by the web browser of the user viewing the web page. Several injection points have been identified on the application. The major one requires the user to be authenticated with a common account, he can then target an Administrator. All others endpoints need the malicious user to be authenticated as an Administrator. Therefore, the impact is diminished.

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.
