CVE-2025-57790
📋 TL;DR
This CVE describes a path traversal vulnerability that allows remote attackers to access files outside intended directories, potentially leading to remote code execution. It affects systems running vulnerable versions of Commvault software. Attackers could read sensitive files or upload malicious content.
💻 Affected Systems
- Commvault software
📦 What is this software?
Commvault by Commvault
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data exfiltration, and lateral movement within the network.
Likely Case
Unauthorized file access including configuration files, credentials, and sensitive data, potentially enabling further attacks.
If Mitigated
Limited impact with proper network segmentation, file system permissions, and input validation controls in place.
🎯 Exploit Status
Path traversal vulnerabilities typically have low exploitation complexity when unauthenticated access is possible
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://documentation.commvault.com/securityadvisories/CV_2025_08_2.html
Restart Required: Yes
Instructions:
1. Review vendor advisory for affected versions. 2. Download and apply the latest security patch from Commvault. 3. Restart affected Commvault services. 4. Verify the patch was successfully applied.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to Commvault services to trusted IP addresses only
# Use firewall rules to limit access
# Example: iptables -A INPUT -p tcp --dport [commvault-port] -s [trusted-ip] -j ACCEPT
File System Permissions Hardening
linuxImplement strict file system permissions to limit potential damage from path traversal
# Set restrictive permissions on sensitive directories
chmod 750 /path/to/commvault/data
chown root:commvault /path/to/commvault/data
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Commvault systems
- Deploy web application firewall (WAF) with path traversal protection rules
🔍 How to Verify
Check if Vulnerable:
Check Commvault version against vendor advisory and test for path traversal using controlled testing methodsCheck Version:
Check Commvault management console or run 'cvpkg list' on Commvault serverVerify Fix Applied:
Verify patch installation through Commvault console and test that path traversal attempts are properly blocked📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns
- Path traversal strings in request logs (../, ..\, %2e%2e/)
- Failed authentication attempts followed by file access
Network Indicators:
- Unusual outbound connections from Commvault servers
- Traffic patterns indicating data exfiltration
SIEM Query:
