CVE-2025-1692

6.3 MEDIUM

📋 TL;DR

This vulnerability allows attackers to inject malicious code into MongoDB Shell (mongosh) through clipboard manipulation. An attacker controlling the user's clipboard can paste obfuscated code containing control characters that gets executed. This affects users running mongosh versions before 2.3.9.

💻 Affected Systems

Products:
  • MongoDB Shell (mongosh)
Versions: All versions prior to 2.3.9
Operating Systems: All platforms where mongosh runs
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects interactive use of mongosh where users paste content from clipboard.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise through arbitrary code execution, potentially leading to data theft, ransomware deployment, or lateral movement within the network.

🟠

Likely Case

Local privilege escalation or unauthorized database access when a user with elevated privileges pastes malicious content into mongosh.

🟢

If Mitigated

Limited impact if users follow security best practices and avoid pasting untrusted content into mongosh sessions.

🌐 Internet-Facing: LOW - mongosh is typically used as a client tool, not exposed directly to the internet.
🏢 Internal Only: MEDIUM - Internal users could be targeted through social engineering or compromised workstations.

🎯 Exploit Status

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

Requires social engineering to trick user into pasting malicious content. Control character obfuscation makes detection difficult.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2.3.9

Vendor Advisory: https://jira.mongodb.org/browse/MONGOSH-2025

Restart Required: No

Instructions:

1. Check current mongosh version with 'mongosh --version'. 2. Update to version 2.3.9 or later using your package manager or MongoDB download page. 3. Verify update with 'mongosh --version'.

🔧 Temporary Workarounds

Disable clipboard pasting

all

Avoid pasting any content from clipboard into mongosh sessions

Use trusted input only

all

Only paste content from trusted sources and verify content before pasting

🧯 If You Can't Patch

  • Implement strict user training about clipboard security risks
  • Restrict mongosh usage to trusted environments only

🔍 How to Verify

Check if Vulnerable:

Run 'mongosh --version' and check if version is less than 2.3.9

Check Version:

mongosh --version

Verify Fix Applied:

Run 'mongosh --version' and confirm version is 2.3.9 or higher

📡 Detection & Monitoring

Log Indicators:

  • Unusual mongosh process behavior
  • Unexpected database operations from mongosh sessions

Network Indicators:

  • Unusual outbound connections from systems running mongosh

SIEM Query:

Process execution where process_name='mongosh' AND (command_line contains unusual characters OR parent_process is suspicious)
