Overview
CVE-2025-64511 is a high-severity security vulnerability affecting MaxKB, an open-source AI assistant for enterprise. This vulnerability allows a malicious user to bypass the intended sandbox environment and gain unauthorized access to internal network services, such as databases. This can be achieved by exploiting Python code execution within the tool module.
The vulnerability exists in MaxKB versions prior to 2.3.1. Users are strongly advised to upgrade to version 2.3.1 or later to mitigate this risk.
Technical Details
The vulnerability stems from insufficient input validation and inadequate restrictions on the Python code that can be executed within MaxKB’s tool module. Although the execution is intended to be sandboxed, a carefully crafted payload can escape the sandbox and interact with internal network resources. Specifically, the exploit leverages the ability to manipulate the Python environment to establish connections to internal services, potentially bypassing firewall rules and access controls that are normally in place.
CVSS Analysis
This vulnerability has been assigned a CVSS score of 7.4, indicating a high severity. This score reflects the potential for significant impact to the confidentiality, integrity, and availability of affected systems.
- CVSS Score: 7.4
- Severity: HIGH
Possible Impact
Successful exploitation of CVE-2025-64511 can have serious consequences, including:
- Data Breach: Unauthorized access to sensitive data stored in internal databases.
- System Compromise: Potential for lateral movement within the internal network, leading to compromise of other systems.
- Denial of Service: Disruption of critical services through unauthorized manipulation of internal resources.
- Reputational Damage: Loss of trust and damage to reputation due to a security breach.
Mitigation and Patch Steps
The primary mitigation is to upgrade to MaxKB version 2.3.1 or later. This version contains the necessary fixes to address the vulnerability.
- Upgrade MaxKB: Follow the official MaxKB upgrade instructions to update to version 2.3.1.
- Verify Installation: After upgrading, verify that the new version is running correctly.
- Monitor Logs: Monitor system logs for any suspicious activity that might indicate attempted exploitation.
