This article will provide insights into CVE-2023-26035, also known as ZoneMinder vulnerable to Missing Authorization.

Understanding CVE-2023-26035

CVE-2023-26035 highlights a vulnerability in the ZoneMinder software, exposing it to potential security risks due to Missing Authorization.

What is CVE-2023-26035?

ZoneMinder is an open-source Closed-circuit television software designed for Linux, supporting various types of cameras. The vulnerability lies in versions prior to 1.36.33 and 1.37.33, allowing Unauthenticated Remote Code Execution through Missing Authorization. Specifically, the issue arises from a lack of permissions check on the snapshot action within the software.

The Impact of CVE-2023-26035

The impact of CVE-2023-26035 is significant, as it enables malicious actors to exploit this vulnerability and execute remote code without proper authorization. This can lead to unauthorized access, data breaches, and potentially system compromise.

Technical Details of CVE-2023-26035

In-depth technical details shed light on the specifics of this vulnerability, providing a better understanding of its implications and how it operates.

Vulnerability Description

The vulnerability allows for Unauthenticated Remote Code Execution via Missing Authorization in ZoneMinder versions prior to 1.36.33 and 1.37.33. The lack of proper permission checks on the snapshot action can be exploited to execute unauthorized code remotely.

Affected Systems and Versions

ZoneMinder versions < 1.36.33 and >= 1.37.0, < 1.37.33 are susceptible to this vulnerability. It is crucial for users of these versions to take immediate action to mitigate potential risks.

Exploitation Mechanism

The exploit occurs due to a lack of permission validation in the snapshot action, allowing attackers to pass an object instead of an expected ID to create a new monitor. Consequently, the system executes shell_exec using the supplied ID, leading to remote code execution.

Mitigation and Prevention

Effective mitigation strategies are essential to address CVE-2023-26035 and safeguard systems from potential exploitation.

Immediate Steps to Take

Users should upgrade ZoneMinder to versions 1.36.33 or 1.37.33, where the vulnerability has been patched.
Implement proper authentication and authorization mechanisms to prevent unauthorized access.
Regularly monitor system logs and network traffic for any suspicious activity.

Long-Term Security Practices

Conduct regular security assessments and audits to identify and address vulnerabilities promptly.
Stay informed about software updates, security patches, and best practices to enhance system security.
Train users on cybersecurity awareness and safe computing practices to mitigate potential risks.

Patching and Updates

It is crucial for users to install the latest patches and updates provided by ZoneMinder to address CVE-2023-26035 effectively. Regularly updating the software ensures that known vulnerabilities are mitigated, enhancing overall system security and resilience.
