JRun 3.0 and 3.1 running on JRun Web Server (JWS) and IIS allows remote attackers to read arbitrary JavaServer Pages (JSP) source code via a request URL containing the source filename ending in (1) "jsp%00" or (2) "js%2570".

Security readout for executives and security teams

This is a legacy JRun issue where a remote requester could make the server reveal JSP source code instead of running it. Exposed source may contain credentials, business logic, or internal paths. The sources do not provide a CVSS score, patch detail, or evidence of active exploitation. Likely limited to organizations still operating legacy JRun 3.0 or 3.1 deployments on JWS or IIS, especially internet-facing applications. Modern stacks are unlikely to be affected unless old systems remain in production or accessible internal networks. Treat as a legacy exposure audit item with potential confidentiality impact. Prioritize if JRun systems are internet-facing or handle credentials, customer data, or sensitive business workflows. Mitigation focus: Inventory systems for JRun 3.0 or 3.1 on JWS or IIS.; Remove internet exposure for any confirmed legacy JRun deployment.; Check archived vendor guidance for official fixes or upgrade paths..
