Description

The password change functionality in Cloud Foundry Runtime cf-release before 216, UAA before 2.5.2, and Pivotal Cloud Foundry (PCF) Elastic Runtime before 1.7.0 allow attackers to have unspecified impact by leveraging failure to expire existing sessions.

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every cloudfoundry cf-release 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. Fix

    Apply the cloudfoundry cf-release security patch or hotfix for CVE-2015-5171 on the affected version, following the vendor advisory for your exact build.

  3. 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.

  4. How O3 protects you

    O3 detects and blocks CVE-2015-5171 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-2015-5171. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
