CVE-2014-3604
CVE-2014-3604 is a CWE-310 vulnerability in not_yet_commons_ssl_project not yet commons ssl. O3 Security detects and blocks CVE-2014-3604 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

Description
Certificates.java in Not Yet Commons SSL before 0.3.15 does not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
Affected Products

Vendor / applianceDetect
Inventory every not_yet_commons_ssl_project not yet commons ssl 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-2014-3604 yet — track the not_yet_commons_ssl_project not yet commons ssl 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-2014-3604 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-2014-3604. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
