Technical Analysis

CVE-2025-52776 is a high-severity vulnerability classified under CWE-79, which corresponds to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the thanhtungtnt Video List Manager product, specifically versions up to 1.7. The flaw allows an attacker to inject malicious scripts that are stored persistently within the application, leading to Stored XSS. When a victim user accesses the affected web pages, the malicious script executes in their browser context. The CVSS v3.1 base score of 7.1 reflects the vulnerability's characteristics: it is remotely exploitable over the network (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability impacts individually, but combined they can lead to significant security issues. Stored XSS can be leveraged to hijack user sessions, deface websites, conduct phishing attacks, or deliver malware. The vulnerability arises from improper input sanitization or encoding during web page generation, allowing malicious payloads to be stored and later rendered unsafely in users' browsers. No patches or fixes are currently linked, and no known exploits in the wild have been reported yet. However, the presence of this vulnerability in a media management tool that may be used by organizations to manage video content poses a tangible risk, especially if the application is accessible publicly or used in multi-user environments.

Potential Impact

For European organizations using thanhtungtnt Video List Manager, this vulnerability could lead to significant security risks. Stored XSS can compromise user accounts, especially if the application manages authentication tokens or sensitive user data. Attackers could exploit this to perform session hijacking, leading to unauthorized access to organizational resources. Additionally, the injection of malicious scripts could facilitate phishing campaigns targeting employees or customers, potentially leading to credential theft or malware infections. The integrity of the video content and associated metadata could be compromised, damaging organizational reputation. Availability impacts, while rated low individually, could manifest through exploitation chains that disrupt service or deface content. Given the high connectivity and regulatory environment in Europe, such as GDPR, exploitation of this vulnerability could also result in compliance violations and financial penalties if personal data is exposed or mishandled. Organizations relying on this product for public-facing or internal video content management should consider the risk of lateral movement or privilege escalation if attackers leverage this XSS as an initial foothold.

Mitigation Recommendations

Specific mitigations should focus on immediate and medium-term actions: 1) Input Validation and Output Encoding: Developers and administrators should ensure that all user-supplied input is properly sanitized and encoded before rendering in the web interface. Employ context-aware output encoding libraries to neutralize script injection vectors. 2) Content Security Policy (CSP): Implement a strict CSP header to restrict the execution of unauthorized scripts and reduce the impact of XSS payloads. 3) Application Updates: Monitor the vendor's communications for patches or updates addressing this vulnerability and apply them promptly once available. 4) Access Controls: Restrict access to the Video List Manager interface to trusted users and networks, minimizing exposure to untrusted actors. 5) User Awareness: Educate users about the risks of clicking on suspicious links or interacting with unexpected content within the application. 6) Web Application Firewall (WAF): Deploy or tune WAF rules to detect and block common XSS attack patterns targeting this application. 7) Incident Response Preparedness: Establish monitoring for anomalous activities related to the application and prepare to respond to potential exploitation attempts. These measures go beyond generic advice by focusing on both technical controls and operational practices tailored to the nature of the vulnerability and the product context.
