CVE-2023-49950 — Logpoint Siem security vulnerability

Medium CVSS 5.4

The Jinja templating in Logpoint SIEM 6.10.0 through 7.x before 7.3.0 does not correctly sanitize log data being displayed when using a custom Jinja template in the Alert view. A remote attacker can craft a cross-site scripting (XSS) payload and send it to any system or device that sends logs to the SIEM. If an alert is created, the payload will execute upon the alert data being viewed with that template, which can lead to sensitive data disclosure.

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.
