EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Description
Unrestricted file upload vulnerability in server/php/UploadHandler.php in the jQuery File Upload Plugin 6.4.4 for jQuery, as used in the Creative Solutions Creative Contact Form (formerly Sexy Contact Form) before 1.0.0 for WordPress and before 2.0.1 for Joomla!, allows remote attackers to execute arbitrary code by uploading a PHP file with an PHP extension, then accessing it via a direct request to the file in files/, as exploited in the wild in October 2014.

Detection & mitigation playbook
Vendor / applianceDetect
Inventory every creative-solutions creative contact form 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 remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Fix
Apply the creative-solutions creative contact form security patch or hotfix for CVE-2014-8739 on the affected version, following the vendor advisory for your exact build.
Workarounds
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-2014-8739 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-2014-8739. 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-2014-8739 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2014-8739 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
