CVE-2025-53664

6.5 MEDIUM

📋 TL;DR

The Jenkins Apica Loadtest Plugin stores authentication tokens in plaintext within job configuration files, allowing users with Item/Extended Read permissions or filesystem access to view these sensitive credentials. This affects Jenkins instances using Apica Loadtest Plugin version 1.10 or earlier. Attackers could steal these tokens to gain unauthorized access to Apica Loadtest services.

💻 Affected Systems

Products:
  • Jenkins Apica Loadtest Plugin
Versions: 1.10 and earlier
Operating Systems: All platforms running Jenkins
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects Jenkins instances with the Apica Loadtest Plugin installed and configured with authentication tokens.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers obtain Apica Loadtest authentication tokens and gain full administrative access to Apica Loadtest services, potentially compromising load testing infrastructure and associated systems.

🟠

Likely Case

Malicious users with Item/Extended Read permissions extract authentication tokens from job configurations and use them to access Apica Loadtest services with the permissions of the token owner.

🟢

If Mitigated

With proper access controls limiting Item/Extended Read permissions and filesystem access, token exposure is minimized to authorized administrators only.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires Item/Extended Read permissions or filesystem access to the Jenkins controller.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.11 or later

Vendor Advisory: https://www.jenkins.io/security/advisory/2025-07-09/#SECURITY-3540

Restart Required: Yes

Instructions:

1. Update Jenkins Apica Loadtest Plugin to version 1.11 or later via Jenkins Plugin Manager. 2. Restart Jenkins to apply the update. 3. Existing tokens in job configurations remain exposed until jobs are reconfigured.

🔧 Temporary Workarounds

Restrict Item/Extended Read Permissions

all

Limit users with Item/Extended Read permissions to trusted administrators only to prevent unauthorized viewing of job configuration files.

Secure Jenkins Controller Filesystem

all

Restrict filesystem access to the Jenkins controller to prevent unauthorized users from reading config.xml files containing plaintext tokens.

🧯 If You Can't Patch

  • Remove Apica Loadtest authentication tokens from existing job configurations and store them securely elsewhere.
  • Rotate all exposed Apica Loadtest authentication tokens immediately to invalidate any stolen credentials.

🔍 How to Verify

Check if Vulnerable:

Check Jenkins plugin manager for Apica Loadtest Plugin version. If version is 1.10 or earlier, the system is vulnerable.

Check Version:

Navigate to Jenkins > Manage Jenkins > Plugin Manager > Installed plugins and check Apica Loadtest Plugin version.

Verify Fix Applied:

Verify Apica Loadtest Plugin version is 1.11 or later in Jenkins plugin manager and confirm authentication tokens are no longer stored in plaintext in job config.xml files.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized access attempts to job configuration files or Apica Loadtest services using stolen tokens

Network Indicators:

  • Unusual API calls to Apica Loadtest services from unexpected IP addresses

SIEM Query:

source="jenkins" AND (event="config_access" OR event="plugin_vulnerability") AND plugin="apica-loadtest"
