CVE-2025-1979

6.4 MEDIUM

📋 TL;DR

Ray versions before 2.43.0 log Redis passwords in standard logging when passed as arguments, potentially exposing authentication credentials. This affects users running Ray with Redis password authentication and logging enabled. Attackers who can access these logs could compromise the Redis instance.

💻 Affected Systems

Products:
  • Ray
Versions: All versions before 2.43.0
Operating Systems: All operating systems running Ray
Default Config Vulnerable: ✅ No
Notes: Requires Redis password authentication enabled and logging enabled; password must be passed as argument.

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Redis password exposure leads to full compromise of Redis instance, allowing data theft, manipulation, or denial of service.

🟠

Likely Case

Redis password leakage to unauthorized personnel or systems, potentially enabling unauthorized access to Redis data.

🟢

If Mitigated

Limited exposure if logs are properly secured and access-controlled, with minimal impact.

🌐 Internet-Facing: MEDIUM - Risk depends on log accessibility; internet-facing systems with exposed logs increase exposure.
🏢 Internal Only: MEDIUM - Internal systems still at risk if logs are accessible to internal attackers or compromised accounts.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW - Attackers only need access to logs containing the password.

Exploitation requires access to logs; no special tools needed beyond log viewing.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2.43.0

Vendor Advisory: https://github.com/ray-project/ray/commit/64a2e4010522d60b90c389634f24df77b603d85d

Restart Required: Yes

Instructions:

1. Update Ray to version 2.43.0 or later using pip: 'pip install --upgrade ray>=2.43.0'. 2. Restart Ray services. 3. Rotate Redis passwords as precaution.

🔧 Temporary Workarounds

Disable logging for sensitive operations

all

Temporarily reduce logging verbosity or disable logging for Ray processes handling Redis authentication.

Configure Ray logging to exclude sensitive arguments or set log level to ERROR/WARNING

Use environment variables for Redis password

linux

Pass Redis password via environment variable instead of command-line argument to avoid logging.

export REDIS_PASSWORD='your_password'
ray start --redis-password=$REDIS_PASSWORD

🧯 If You Can't Patch

  • Secure log files with strict access controls and encryption; restrict log access to authorized personnel only.
  • Rotate Redis passwords immediately and monitor logs for any password exposure.

🔍 How to Verify

Check if Vulnerable:

Check Ray version: if below 2.43.0 and using Redis password authentication with logging, system is vulnerable.

Check Version:

python -c "import ray; print(ray.__version__)"

Verify Fix Applied:

After updating to 2.43.0+, verify no Redis passwords appear in logs when starting Ray with password arguments.

📡 Detection & Monitoring

Log Indicators:

  • Log entries containing Redis password strings, especially in Ray startup logs or authentication attempts.

Network Indicators:

  • Unauthorized access attempts to Redis instance using potentially leaked credentials.

SIEM Query:

source="ray_logs" AND "redis" AND "password"
