Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Apache ActiveMQ's Jetty ResourceHandler has a flaw. π **Consequences**: Remote attackers can read **JSP source code** via specific URIs starting with '//'. This exposes sensitive backend logic!
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Flaw in **Jetty ResourceHandler**. π **CWE**: Information Disclosure (Source Code). The handler incorrectly processes URI substrings starting with '//'.
Q3Who is affected? (Versions/Components)
π― **Affected**: Apache ActiveMQ (Open Source Message Middleware). π¦ **Components**: Specifically the **Jetty** embedded server component used for the admin interface.
Q4What can hackers do? (Privileges/Data)
π» **Attacker Action**: Read **JSP source code**. π΅οΈ **Data Exposed**: Backend JavaServer Pages logic from admin pages like `admin/index.jsp`, `admin/queues.jsp`, or `admin/topics.jsp`.
Q5Is exploitation threshold high? (Auth/Config)
βοΈ **Threshold**: Medium. π **Access**: Requires network access to the admin URIs.β¦
π’ **Exploit Status**: Yes, public advisories exist (OSVDB-64020, SECUNIA-39567, BID-39636). π **Published**: April 2010. Wild exploitation likely existed post-disclosure.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for ActiveMQ admin pages. π§ͺ **Test**: Request URIs like `admin/index.jsp//` or similar patterns starting with '//'. If source code is returned instead of execution, you are vulnerable!
Q8Is it fixed officially? (Patch/Mitigation)
π§ **Fix**: Official patches were released by Apache. π **Status**: This is a **2010** vulnerability. All modern versions are fixed. Update to the latest stable release immediately if still running old versions.
Q9What if no patch? (Workaround)
π§ **No Patch?**: Restrict access to admin interfaces (`/admin/*`). π **Network**: Block external access to Jetty admin ports. π **WAF**: Configure rules to block URIs containing `//` in the admin path.
Q10Is it urgent? (Priority Suggestion)
β οΈ **Priority**: **Low** for modern systems, **High** for legacy. π **Age**: 14+ years old. If you are still running unpatched ActiveMQ from 2010, you have bigger problems! π
