How do I patch CVE-2014-3840?

No patch has shipped for CVE-2014-3840 yet — track the mayan-edms mayan edms advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2014-3840 across my infrastructure?

Inventory every mayan-edms mayan edms 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.

How do I mitigate CVE-2014-3840 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2014-3840?

O3 detects and blocks CVE-2014-3840 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2014-3840 actively exploited in the wild?

Yes. There are 3 known exploit references for CVE-2014-3840, including 1 documented proof-of-concept exploit on Exploit-DB and 2 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2014-3840?

CVE-2014-3840 has an EPSS (Exploit Prediction Scoring System) score of 3.5%, placing it in the 88th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2014-3840?

CVE-2014-3840 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2014-3840?

CVE-2014-3840 affects mayan-edms mayan edms (1 version, e.g. 0.13). Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2014-3840 published, and has it been updated?

CVE-2014-3840 was published on May 27, 2014 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
