CVE-2025-24389

6.3 MEDIUM

📋 TL;DR

This vulnerability causes sensitive information to be inadvertently logged and emailed to administrators when upstream library errors occur in OTRS systems. It affects OTRS 7.0.X, 8.0.X, 2023.X, 2024.X, and ((OTRS)) Community Edition 6.0.x. Products based on the Community Edition are also likely affected.

💻 Affected Systems

Products:
  • OTRS
  • ((OTRS)) Community Edition
Versions: OTRS 7.0.X, 8.0.X, 2023.X, 2024.X; ((OTRS)) Community Edition 6.0.x
Operating Systems: All platforms running affected OTRS versions
Default Config Vulnerable: ⚠️ Yes
Notes: Products based on ((OTRS)) Community Edition are also likely affected. The vulnerability occurs when upstream library errors trigger logging/email mechanisms.

⚠️ 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

Sensitive data such as credentials, API keys, or personal information could be exposed in logs and emails, potentially leading to data breaches or credential theft.

🟠

Likely Case

Administrators receive emails containing sensitive information that could be intercepted or accessed by unauthorized personnel with access to mail systems or log files.

🟢

If Mitigated

With proper access controls and log monitoring, exposure is limited to authorized administrators, though the sensitive data remains in logs.

🌐 Internet-Facing: MEDIUM - While the vulnerability doesn't directly expose data externally, logs or emails containing sensitive info could be intercepted if systems are compromised.
🏢 Internal Only: HIGH - Internal users with access to logs or administrator emails could view sensitive information that should not be exposed.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW - The vulnerability is triggered by normal error conditions rather than requiring active exploitation.

Exploitation doesn't require attacker action - it occurs naturally when upstream library errors happen. The risk is information exposure rather than system compromise.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check vendor advisory for specific patched versions

Vendor Advisory: https://otrs.com/release-notes/otrs-security-advisory-2025-03/

Restart Required: Yes

Instructions:

1. Review the vendor advisory for specific patch versions. 2. Backup your OTRS installation and database. 3. Apply the appropriate patch for your version. 4. Restart the OTRS service. 5. Verify the fix by checking version and monitoring logs.

🔧 Temporary Workarounds

Restrict Log and Email Access

linux

Limit access to OTRS log files and administrator email accounts to reduce exposure of sensitive information.

chmod 640 /path/to/otrs/logs/*
chown root:otrs /path/to/otrs/logs/*

Disable Error Email Notifications

all

Temporarily disable email notifications for system errors to prevent sensitive data from being emailed.

Update OTRS System Configuration: SysConfig -> Core -> SendmailModule -> disable error notifications

🧯 If You Can't Patch

  • Implement strict access controls on log directories and administrator email accounts
  • Monitor logs for sensitive information exposure and implement alerting for such occurrences

🔍 How to Verify

Check if Vulnerable:

Check your OTRS version against affected versions: OTRS 7.0.X, 8.0.X, 2023.X, 2024.X, or ((OTRS)) Community Edition 6.0.x

Check Version:

cat /opt/otrs/RELEASE | grep VERSION or check via OTRS admin interface

Verify Fix Applied:

After patching, verify the version is no longer in the affected range and monitor logs/emails for continued sensitive information exposure.

📡 Detection & Monitoring

Log Indicators:

  • Log entries containing sensitive data like passwords, API keys, or personal information
  • Error messages from upstream libraries that include sensitive context

Network Indicators:

  • Unusual email traffic containing system error information
  • External access attempts to log files

SIEM Query:

source="otrs.log" AND (password OR api_key OR secret OR token) NOT IN expected_context
