Description

JBoss AS 7 prior to 7.1.1 and mod_cluster do not handle default hostname in the same way, which can cause the excluded-contexts list to be mismatched and the root context to be exposed.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jboss.as:jboss-as-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jboss.as:jboss-as-server to 7.1.1.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2012-1094 is resolved across your whole dependency graph.

  3. Workarounds

    Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
