Description
Spooler in Apache Foundation James 2.2.0 allows local users to cause a denial of service (memory consumption) by triggering various error conditions in the retrieve function, which prevents a lock from being released and causes a memory leak.
Affected Products
jamesapacheDetection & mitigation playbook
Vendor / applianceDetect
Inventory every apache james deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Remediation status
No patch has shipped for CVE-2004-2650 yet — track the apache james advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2004-2650 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2004-2650. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2004-2650 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2004-2650 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
