CVE-2025-59792
📋 TL;DR
The CVE-2025-59792 vulnerability in Apache Kvrocks allows attackers to obtain plaintext credentials through the MONITOR command. This affects all Apache Kvrocks deployments running versions 1.0.0 through 2.13.0. Attackers with access to the MONITOR command can potentially capture sensitive authentication information.
💻 Affected Systems
- Apache Kvrocks
📦 What is this software?
Kvrocks by Apache
⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain administrative credentials, leading to complete system compromise, data exfiltration, or lateral movement within the network.
Likely Case
Unauthorized users capture valid credentials, gaining access to the Kvrocks instance and potentially sensitive data stored within it.
If Mitigated
Credential exposure is limited to authorized users only, preventing external attackers from accessing sensitive information.
🎯 Exploit Status
Exploitation requires access to the MONITOR command, which typically requires some level of authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.14.0
Vendor Advisory: https://lists.apache.org/thread/h2pcvr5p9otc7dnj2dt2nr4b3omghddw
Restart Required: Yes
Instructions:
1. Download Apache Kvrocks 2.14.0 from official sources. 2. Stop the Kvrocks service. 3. Backup configuration and data. 4. Install version 2.14.0. 5. Restart the Kvrocks service. 6. Verify the upgrade was successful.
🔧 Temporary Workarounds
Disable MONITOR Command
allRestrict or disable the MONITOR command to prevent credential exposure.
# Configure Kvrocks to disable MONITOR command in configuration file
# Add 'monitor-command no' to kvrocks.conf
Network Access Control
linuxRestrict network access to Kvrocks instances to trusted sources only.
# Use firewall rules to limit access
iptables -A INPUT -p tcp --dport 6666 -s trusted_ip -j ACCEPT
iptables -A INPUT -p tcp --dport 6666 -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation and access controls to limit who can connect to Kvrocks instances.
- Monitor and audit all access to Kvrocks instances, particularly MONITOR command usage, for suspicious activity.
🔍 How to Verify
Check if Vulnerable:
Check the Kvrocks version using the INFO command or by examining the service version. If version is between 1.0.0 and 2.13.0 inclusive, the system is vulnerable.
Check Version:
redis-cli -h localhost -p 6666 INFO | grep redis_version
Verify Fix Applied:
After upgrading, verify the version is 2.14.0 or higher using the INFO command or version check.
📡 Detection & Monitoring
Log Indicators:
