Security readout for executives and security teams

This is an old information-disclosure issue in Allaire JRun 3.0. A remote attacker could use a malformed URL to view the protected WEB-INF directory and web.xml file, potentially exposing application configuration details. The sources do not provide a CVSS score or confirm active exploitation. Exposure is likely limited to legacy environments still running Allaire JRun 3.0 and serving applications directly or indirectly to untrusted users. Modern stacks are unlikely to be affected unless an old JRun deployment remains in production, test, or archival infrastructure. Prioritize investigation if legacy Java application servers remain exposed. The business risk is leakage of application configuration, which can assist follow-on attacks. If no Allaire JRun 3.0 exists, no further action is likely needed beyond documentation. Mitigation focus: Review Allaire advisory ASB01-02 for vendor-approved corrective guidance.; Inventory environments for any remaining Allaire JRun 3.0 deployments.; Remove or isolate internet-facing JRun 3.0 instances where feasible..
