CVE-2025-2877

6.5 MEDIUM

📋 TL;DR

This vulnerability in Ansible Automation Platform's Event-Driven Ansible exposes inventory passwords in plain text when debug verbosity is enabled during rulebook activation. It affects any debug action in rulebooks and Event Streams, potentially allowing attackers to obtain sensitive credentials. Organizations using Ansible Automation Platform with debug logging enabled are affected.

💻 Affected Systems

Products:
  • Ansible Automation Platform
  • Event-Driven Ansible
  • Ansible Rulebooks
Versions: Specific versions listed in Red Hat advisories RHSA-2025:3636 and RHSA-2025:3637
Operating Systems: Linux (RHEL-based distributions)
Default Config Vulnerable: ✅ No
Notes: Only vulnerable when verbosity is set to 'debug' in configurations

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers gain access to inventory passwords, leading to lateral movement, privilege escalation, and complete compromise of managed systems.

🟠

Likely Case

Unauthorized users with access to logs or debug output can harvest credentials for targeted attacks on infrastructure.

🟢

If Mitigated

With debug logging disabled and proper access controls, exposure is limited to authorized administrators only.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

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

Exploitation requires access to debug logs or output where passwords are exposed

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Versions specified in RHSA-2025:3636 and RHSA-2025:3637

Vendor Advisory: https://access.redhat.com/errata/RHSA-2025:3636

Restart Required: Yes

Instructions:

1. Update Ansible Automation Platform using Red Hat Satellite or repository. 2. Apply patches for affected components. 3. Restart Event-Driven Ansible services. 4. Verify debug logging no longer exposes passwords.

🔧 Temporary Workarounds

Disable Debug Verbosity

linux

Set verbosity to levels below 'debug' in all rulebook configurations

ansible-config set DEFAULT_VERBOSITY=2
Edit rulebook YAML files to remove 'verbosity: debug'

Restrict Log Access

linux

Implement strict file permissions and access controls on Ansible log directories

chmod 640 /var/log/ansible/*
setfacl -m u:ansible:r-x /var/log/ansible/

🧯 If You Can't Patch

  • Immediately disable debug verbosity in all rulebook configurations
  • Rotate all inventory passwords and implement credential monitoring

🔍 How to Verify

Check if Vulnerable:

Check if any rulebook configurations have 'verbosity: debug' set and test activation to see if passwords appear in logs

Check Version:

ansible --version | grep 'ansible package'

Verify Fix Applied:

After patching, test rulebook activation with debug verbosity and confirm passwords are masked in output

📡 Detection & Monitoring

Log Indicators:

  • Plaintext passwords in ansible.log files
  • Debug output containing 'password=' or similar patterns

Network Indicators:

  • Unusual authentication attempts from systems that accessed debug logs

SIEM Query:

source="ansible.log" AND "password=" AND "debug"
