Vulnerability Details
The CVE description notes that this vulnerability allows stored XSS due to CSRF in the MDC YouTube Downloader plugin. The vulnerability is classified under CWE-352, indicating its nature as a CSRF vulnerability. The CVSS score of 7.1 reflects a high severity level, indicating the need for prompt remediation. The affected product is the MDC YouTube Downloader, with the vendor being the mdc_youtube_downloader_project.
Technical Analysis
The root cause of this vulnerability lies in the inadequacy of CSRF protections within the MDC YouTube Downloader. The attack vector is via network, and the complexity of the attack is low, meaning that it does not require advanced skills for exploitation. No privileges are required for an attacker to exploit this vulnerability, but user interaction is necessary for the execution of the malicious request.
The impacts include low confidentiality, integrity, and availability, as attackers can execute actions on behalf of users, leveraging their session without their consent. This vulnerability can lead to unauthorized actions being taken within the application, potentially compromising user data.
Risk & Impact Analysis
Real-world deployment of the MDC YouTube Downloader with this vulnerability presents a significant risk. Attackers may exploit CSRF to perform actions on behalf of users, leading to unauthorized access and data manipulation. This could result in a breach where attackers can take control of user sessions, affecting not just the immediate targets but potentially broader user bases.
The urgency assessment based on the CVSS score indicates that organizations should act swiftly to patch this vulnerability. The potential impact on users and the organization’s reputation reinforces the need for immediate remediation efforts.
