CVE-2017-7463 — JBoss BRMS 6 and BPM Suite 6 before 6.4.3 are vulnerable to a reflected XSS via artifact upload

Medium CVSS 6.1

JBoss BRMS 6 and BPM Suite 6 before 6.4.3 are vulnerable to a reflected XSS via artifact upload. A malformed XML file, if uploaded, causes an error message to appear that includes part of the bad XML code verbatim without filtering out scripts. Successful exploitation would allow execution of script code within the context of the affected user.

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.
