CVE-2023-26032 : Vulnerability Insights and Analysis

This CVE advisory discusses a SQL injection vulnerability found in the ZoneMinder application, affecting versions prior to 1.36.33 and 1.37.33.

Understanding CVE-2023-26032

This section delves into the details of the vulnerability, its impact, technical aspects, and mitigation strategies.

What is CVE-2023-26032?

CVE-2023-26032 refers to a SQL injection vulnerability present in ZoneMinder, an open-source Closed-circuit television software application designed for Linux. The vulnerability exists in versions of the software before 1.36.33 and 1.37.33. It occurs due to improper neutralization of special elements used in an SQL command, specifically through a malicious Jason Web Token (JWT).

The Impact of CVE-2023-26032

The vulnerability poses a significant risk as attackers could potentially exploit it to execute arbitrary SQL commands. By crafting a malicious JWT token with the correct HASH key, an attacker can manipulate the Username field within the token to inject malicious SQL queries. This could lead to unauthorized data access, data manipulation, and potentially complete system compromise.

Technical Details of CVE-2023-26032

In this section, we will explore the technical aspects of the CVE-2023-26032 vulnerability.

Vulnerability Description

The vulnerability arises from the trust placed in the Username field of a JWT token during SQL queries to load user data. Attackers leveraging this vulnerability can abuse the trust relationship to inject and execute arbitrary SQL commands within the application's backend database.

Affected Systems and Versions

ZoneMinder versions prior to 1.36.33 and 1.37.33 are susceptible to this SQL injection flaw. Specifically, versions "< 1.36.33" and ">= 1.37.0, < 1.37.33" are identified as being impacted.

Exploitation Mechanism

The exploitation of this vulnerability involves crafting a malicious JWT token, manipulating the Username field within the token, and utilizing it to execute unauthorized SQL operations within the application's database.

Mitigation and Prevention

To safeguard against CVE-2023-26032 and similar vulnerabilities, it is crucial to follow immediate steps, implement long-term security practices, and apply necessary patches and updates.

Immediate Steps to Take

Upgrade ZoneMinder to versions 1.36.33 or 1.37.33, as these contain fixes for the SQL injection vulnerability.
Monitor and review all JWT tokens generated within the application for any suspicious activity.

Long-Term Security Practices

Regularly audit and sanitize user input to prevent SQL injection attacks.
Implement principle of least privilege to restrict access and limit potential damage in case of a breach.

Patching and Updates

Stay informed about security advisories from ZoneMinder and promptly apply patches or updates provided by the vendor to address known vulnerabilities and enhance the security posture of the application.
