In a recent security advisory issued by the SEC Consult Vulnerability Lab, a critical vulnerability was identified in the edu-sharing software developed by metaVentis GmbH. The vulnerability, identified as CVE-2024-28147, pertains to arbitrary file upload functionality within the software, posing a high level of risk to users and organizations utilizing the affected versions.
The specific versions vulnerable to this exploit include those prior to 8.0.8-RC2, 8.1.4-RC0, and 9.0.0-RC19, while the fixed versions have been released as 8.0.8-RC2, 8.1.4-RC0, and 9.0.0-RC19 or later. The impact of this vulnerability is significant, as it allows an authenticated user to upload arbitrary files through the collection preview image upload function. This uploaded content could include malicious JavaScript code, leading to stored cross-site scripting (XSS) attacks or denial of service (DoS) incidents when accessed by other users.
The proof of concept provided by the SEC Consult Vulnerability Lab demonstrates how an attacker can manipulate the file upload process to inject harmful scripts into the platform. By exploiting the mimetype parameter and uploading HTML or SVG files with malicious content, threat actors can execute unauthorized code and disrupt the normal operations of the edu-sharing software.
Following the discovery of this critical vulnerability on April 4, 2024, the SEC Consult team immediately engaged with the vendor, metaVentis GmbH, to address the issue. The vendor responded promptly, acknowledging the security concern and initiating the patch development process. Through collaborative efforts, the affected versions were identified, fixes were implemented, and new versions were published to safeguard users against potential exploitation.
In light of this security incident, SEC Consult advises all edu-sharing software users to apply the provided patch without delay to mitigate the risk of unauthorized file uploads and malicious activities on the platform. Additionally, organizations are encouraged to conduct a comprehensive security review of their systems by qualified professionals to identify and address any other potential vulnerabilities that may exist.
As part of their ongoing commitment to enhancing cybersecurity practices, the SEC Consult team emphasizes the importance of proactive defense measures, regular security assessments, and timely application of software updates to uphold data integrity and protect sensitive information. By staying vigilant and responsive to emerging threats, organizations can fortify their defenses against malicious attacks and maintain a secure operating environment.
