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: 0.34% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: jbossas (Red Hat:jboss_enterprise_application_platform:5::el5) 0:5.2.0-23.ep5.el5; jbossas-client (Red Hat:jboss_enterprise_application_platform:5::el5) 0:5.2.0-23.ep5.el5; jbossas-messaging (Red Hat:jboss_enterprise_application_platform:5::el5) 0:5.2.0-23.ep5.el5.
Low priority for now. Upgrade to jbossas (Red Hat:jboss_enterprise_application_platform:5::el5) 0:5.2.0-23.ep5.el5; jbossas-client (Red Hat:jboss_enterprise_application_platform:5::el5) 0:5.2.0-23.ep5.el5; jbossas-messaging (Red Hat:jboss_enterprise_application_platform:5::el5) 0:5.2.0-23.ep5.el5 or later.
