Urgent: Apache Kvrocks Flaw (CVE-2025-59792) Leaks Plaintext Credentials!

by

Overview

A medium-severity vulnerability, identified as CVE-2025-59792, affects Apache Kvrocks versions 1.0.0 through 2.13.0. This flaw allows attackers to potentially capture plaintext credentials due to insufficient sanitization when using the MONITOR command. This can lead to unauthorized access and data breaches.

Technical Details

The MONITOR command in Apache Kvrocks is designed to provide a real-time stream of commands processed by the server. However, a security vulnerability exists where the output of the MONITOR command might reveal sensitive information, including plaintext credentials if they are being passed as part of the Redis protocol commands. Attackers with sufficient privileges to execute the MONITOR command (or access to its output) can potentially intercept these credentials.

Specifically, the vulnerability arises because the Kvrocks server does not adequately sanitize or mask credential information before it is displayed through the MONITOR output stream. Any command containing usernames, passwords, or API keys will be visible in the stream if an attacker is monitoring the server.

CVSS Analysis

The Common Vulnerability Scoring System (CVSS) score for CVE-2025-59792 is 5.3 (Medium).

  • Attack Vector (AV): Network (N)
  • Attack Complexity (AC): Low (L)
  • Privileges Required (PR): Low (L)
  • User Interaction (UI): None (N)
  • Scope (S): Unchanged (U)
  • Confidentiality Impact (C): High (H)
  • Integrity Impact (I): None (N)
  • Availability Impact (A): None (N)

This score indicates that the vulnerability is exploitable over the network, requires low privileges, and has a high impact on confidentiality. While integrity and availability are not directly impacted, the compromise of credentials can lead to further exploitation that affects these areas as well.

Possible Impact

The exploitation of CVE-2025-59792 can have significant consequences:

  • Credential Theft: Attackers can steal usernames, passwords, and API keys.
  • Unauthorized Access: Stolen credentials can be used to gain unauthorized access to the Kvrocks database and other systems.
  • Data Breaches: Compromised credentials can lead to data breaches and the exposure of sensitive information.
  • Lateral Movement: Attackers can use the compromised Kvrocks instance as a pivot point to attack other systems on the network.

Mitigation and Patch Steps

To mitigate the risk posed by CVE-2025-59792, users of Apache Kvrocks are strongly advised to upgrade to version 2.14.0 or later.

  1. Upgrade Kvrocks: Download and install version 2.14.0 or a more recent version from the official Apache Kvrocks website.
  2. Restrict Access to MONITOR: Limit access to the MONITOR command to only trusted users and systems. Use the Kvrocks authentication mechanisms to enforce access control.
  3. Credential Rotation: Rotate any credentials that may have been exposed by the vulnerability.
  4. Monitor Logs: Monitor Kvrocks logs for suspicious activity and unauthorized access attempts.
