CVE-2015-3198
HIGHCVE-2015-3198 is a high-severity (CVSS 7.5) Information Exposure vulnerability in redhat jboss wildfly application server. O3 Security detects and blocks CVE-2015-3198 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.
The Undertow module of WildFly 9.x before 9.0.0.CR2 and 10.x before 10.0.0.Alpha1 allows remote attackers to obtain the source code of a JSP page via a "/" at the end of a URL.
Description

Vendor / applianceDetect
Inventory every redhat jboss wildfly application server 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-2015-3198 yet — track the redhat jboss wildfly application server 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-2015-3198 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-2015-3198. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
