Noroxi assessment

Priority: Monitor (action score 19/100)

  • 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: 0.53% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: org.wildfly:wildfly-parent (Maven) 23.0.2.Final; eap7-elytron-web (Red Hat:jboss_enterprise_application_platform:7.3::el6) 0:1.6.3-1.Final_redhat_00001.1.el6eap; eap7-hal-console (Red Hat:jboss_enterprise_application_platform:7.3::el6) 0:3.2.15-1.Final_redhat_00001.1.el6eap.

Low priority for now. Upgrade to org.wildfly:wildfly-parent (Maven) 23.0.2.Final; eap7-elytron-web (Red Hat:jboss_enterprise_application_platform:7.3::el6) 0:1.6.3-1.Final_redhat_00001.1.el6eap; eap7-hal-console (Red Hat:jboss_enterprise_application_platform:7.3::el6) 0:3.2.15-1.Final_redhat_00001.1.el6eap or later.

Limit the impact of XSS

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
