CVE-2023-26061 Explained : Impact and Mitigation

An issue was discovered in Nokia NetAct before 22 FP2211 where users can create a script to inject XSS on the Scheduled Search tab under the Alarm Reports Dashboard page. Input validation was missing during the creation of a scheduled task, potentially allowing for cross-site scripting attacks. Although difficult for an external attacker to exploit due to the requirement of specific parameters, such as Jsession-id, a CSRF token, and an Nxsrf token, internal users could realistically perform the attack.

Understanding CVE-2023-26061

This section delves into the details of CVE-2023-26061, providing insights into the vulnerability, impact, affected systems, exploitation mechanism, and mitigation strategies.

What is CVE-2023-26061?

CVE-2023-26061 refers to a vulnerability in Nokia NetAct that allows users to inject cross-site scripting (XSS) via a script created on the Scheduled Search tab, posing a security risk due to missing input validation.

The Impact of CVE-2023-26061

The vulnerability could lead to a high impact on confidentiality, allowing for potential data breaches and unauthorized access to sensitive information. While the integrity and availability are not directly impacted, the potential for XSS attacks can disrupt normal system operation and compromise user data.

Technical Details of CVE-2023-26061

Exploring the technical aspects of CVE-2023-26061 provides a deeper understanding of the vulnerability, affected systems, and exploitation vectors.

Vulnerability Description

The vulnerability in Nokia NetAct allows users to execute XSS attacks by creating scripts on the Scheduled Search tab without proper input validation, posing a risk to system security and user data confidentiality.

Affected Systems and Versions

The affected systems include Nokia NetAct versions prior to 22 FP2211, exposing users to the XSS vulnerability when creating scripts in the Scheduled Search tab.

Exploitation Mechanism

Exploiting CVE-2023-26061 requires internal user access and knowledge of specific parameters, such as Jsession-id, a CSRF token, and an Nxsrf token. External attackers would find it challenging to exploit this vulnerability due to these requirements.

Mitigation and Prevention

Implementing robust mitigation measures is crucial to protect systems from CVE-2023-26061 and prevent potential security breaches.

Immediate Steps to Take

Users and administrators should apply caution when creating scripts in the Scheduled Search tab and ensure that input validation mechanisms are in place to prevent XSS attacks. Regular monitoring of user activities can help detect any unauthorized script creations.

Long-Term Security Practices

Establishing a comprehensive security policy that includes regular security assessments, user training on safe scripting practices, and prompt response to vulnerabilities can enhance the long-term security posture of the system.

Patching and Updates

Vendor patches and updates should be applied promptly to address the vulnerability in Nokia NetAct. Regularly checking for security advisories and applying patches can help mitigate the risk of exploitation through vulnerabilities like CVE-2023-26061.
