CVE-2025-59790
📋 TL;DR
CVE-2025-59790 is an improper privilege management vulnerability in Apache Kvrocks that could allow authenticated users to escalate privileges beyond their intended permissions. This affects Apache Kvrocks installations running versions 2.9.0 through 2.13.0. Organizations using affected versions should prioritize patching to prevent potential unauthorized access to sensitive data or system resources.
💻 Affected Systems
- Apache Kvrocks
📦 What is this software?
Kvrocks by Apache
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could gain administrative privileges, potentially leading to data exfiltration, data manipulation, or complete system compromise of the Kvrocks instance.
Likely Case
Authenticated users could access data or perform operations beyond their authorized permissions, leading to data integrity issues or unauthorized data access.
If Mitigated
With proper network segmentation and minimal user privileges, impact would be limited to the Kvrocks instance itself rather than broader system compromise.
🎯 Exploit Status
Exploitation requires authenticated access to the Kvrocks instance. No public exploit code has been released as of the advisory date.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.14.0
Vendor Advisory: https://lists.apache.org/thread/dlbz5hmm4ts3npzqnvhofxmqg9w9zt0o
Restart Required: Yes
Instructions:
1. Download Apache Kvrocks version 2.14.0 from the official Apache repository. 2. Stop the running Kvrocks service. 3. Replace the existing Kvrocks binary with the patched version. 4. Restart the Kvrocks service. 5. Verify the version is now 2.14.0.
🔧 Temporary Workarounds
Restrict User Privileges
allImplement strict least-privilege access controls to limit potential damage from privilege escalation
# Review and minimize user permissions in Kvrocks configuration
# Use ACLs to restrict user access to only necessary commands
Network Segmentation
allIsolate Kvrocks instances from sensitive systems and limit network access
# Configure firewall rules to restrict access to Kvrocks port
# Implement network segmentation to contain potential breaches
🧯 If You Can't Patch
- Implement strict network access controls to limit which systems can connect to Kvrocks
- Apply principle of least privilege to all user accounts and monitor for unusual activity
🔍 How to Verify
Check if Vulnerable:
Check the Kvrocks version using the INFO command or by examining the service startup logsCheck Version:
redis-cli -h <hostname> -p <port> INFO | grep redis_versionVerify Fix Applied:
Confirm the version is 2.14.0 or higher using the INFO command or version check📡 Detection & Monitoring
Log Indicators:
- Unusual privilege escalation attempts
- Users accessing commands beyond their normal permissions
- Authentication logs showing unexpected user behavior
Network Indicators:
- Unusual patterns of commands from authenticated users
- Increased rate of administrative commands from non-admin users
