The Impact of CVE-2024-23345

The impact of CVE-2024-23345 is rated high, with a CVSS v3.1 base score of 7.1. The vulnerability requires low privileges for exploitation, and user interaction is necessary. It can result in compromised data integrity and pose a threat to affected systems.

Technical Details of CVE-2024-23345

This section delves into the vulnerability description, affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description

The CVE-2024-23345 vulnerability stems from inadequate input sanitization in user-editable fields supporting Markdown rendering in Nautobot versions prior to 1.6.10 or 2.1.2. Attackers can exploit this weakness to execute malicious scripts and perform cross-site scripting attacks.

Affected Systems and Versions

Nautobot versions below 1.6.10 and 2.1.2 are susceptible to CVE-2024-23345. Systems running these versions are at risk of XSS attacks through the manipulation of user-editable fields supporting Markdown rendering.

Exploitation Mechanism

Threat actors can exploit CVE-2024-23345 by injecting crafted malicious data into vulnerable user-editable fields that render Markdown content. This manipulation enables the execution of unauthorized scripts within the application, leading to potential security breaches.

Mitigation and Prevention

To address CVE-2024-23345 and enhance security measures, organizations and users should implement immediate steps, adopt long-term security practices, and prioritize patching and updates.

Immediate Steps to Take

Immediately update Nautobot to versions 1.6.10 or 2.1.2 to mitigate the CVE-2024-23345 vulnerability. Conduct a thorough review of user-editable fields supporting Markdown rendering to ensure they are not manipulated by malicious scripts.

Long-Term Security Practices

Enhance security practices by regularly auditing input validation mechanisms and ensuring proper sanitization of user-generated content. Educate users on safe data input practices to prevent XSS vulnerabilities.

Patching and Updates

Stay informed about security advisories and releases from Nautobot to promptly apply patches and updates. Regularly monitor for vulnerability disclosures and prioritize the maintenance of up-to-date software versions to strengthen overall security posture.
