CVE-2023-24441 Explained : Impact and Mitigation

This article provides detailed information about CVE-2023-24441, a vulnerability identified in Jenkins MSTest Plugin.

Understanding CVE-2023-24441

CVE-2023-24441 is a security vulnerability found in Jenkins MSTest Plugin, specifically affecting versions 1.0.0 and earlier. The issue stems from the plugin's failure to configure its XML parser properly, leaving it vulnerable to XML external entity (XXE) attacks.

What is CVE-2023-24441?

The CVE-2023-24441 vulnerability pertains to Jenkins MSTest Plugin versions 1.0.0 and earlier, which lack proper configuration of their XML parser to safeguard against XML external entity (XXE) attacks. This oversight puts systems at risk of exploitation by malicious entities aiming to manipulate XML data through external entities.

The Impact of CVE-2023-24441

The impact of CVE-2023-24441 can be significant, potentially leading to unauthorized access, data manipulation, or information disclosure on systems utilizing Jenkins MSTest Plugin versions 1.0.0 and earlier. Attackers exploiting this vulnerability could compromise the integrity and confidentiality of XML data processed by the plugin.

Technical Details of CVE-2023-24441

The technical details of CVE-2023-24441 shed light on the vulnerability's characteristics and how it can be exploited.

Vulnerability Description

The vulnerability arises from the inadequate configuration of the XML parser in Jenkins MSTest Plugin versions 1.0.0 and earlier, making them susceptible to XML external entity (XXE) attacks. By leveraging this weakness, threat actors can craft malicious XML payloads to trigger unexpected behaviors and compromise the affected systems.

Affected Systems and Versions

Jenkins MSTest Plugin versions 1.0.0 and earlier are known to be impacted by CVE-2023-24441. Organizations using these specific versions of the plugin are at risk of exploitation if adequate security measures are not implemented promptly.

Exploitation Mechanism
