HighCVSS 7.5 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 3.1% (FIRST EPSS); higher than 88.1% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: mod_cluster (Red Hat:jboss_enterprise_web_server:1::el4) 0:1.0.10-3.GA_CP02.ep5.el4; mod_cluster-demo (Red Hat:jboss_enterprise_web_server:1::el4) 0:1.0.10-3.GA_CP02.ep5.el4; mod_cluster-jbossas (Red Hat:jboss_enterprise_web_server:1::el4) 0:1.0.10-3.GA_CP02.ep5.el4.

Low priority for now. Upgrade to mod_cluster (Red Hat:jboss_enterprise_web_server:1::el4) 0:1.0.10-3.GA_CP02.ep5.el4; mod_cluster-demo (Red Hat:jboss_enterprise_web_server:1::el4) 0:1.0.10-3.GA_CP02.ep5.el4; mod_cluster-jbossas (Red Hat:jboss_enterprise_web_server:1::el4) 0:1.0.10-3.GA_CP02.ep5.el4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

mod_cluster in JBoss Enterprise Application Platform 5.1.2 for Red Hat Linux allows worker nodes to register with arbitrary virtual hosts, which allows remote attackers to bypass intended access restrictions and provide malicious content, hijack sessions, and steal credentials by registering from an external vhost that does not enforce security constraints.
