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

The input fields of the Apache Pluto "Chat Room" demo portlet 3.0.0 and 3.0.1 are vulnerable to Cross-Site Scripting (XSS) attacks. Mitigation: * Uninstall the ChatRoomDemo war file - or - * migrate to version 3.1.0 of the chat-room-demo war file

Apache Pluto 3.0.0 / 3.0.1 - Persistent Cross-Site Scripting

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every apache pluto 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.

  2. Remediation status

    No patch has shipped for CVE-2019-0186 yet — track the apache pluto advisory for a fixed release and apply the workarounds below in the meantime.

  3. 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.

  4. How O3 protects you

    O3 detects and blocks CVE-2019-0186 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-2019-0186. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Is CVE-2019-0186 being exploited in your environment?

O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2019-0186 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
