Overview
CVE-2025-52821 is a significant security vulnerability, which affects the popular video management software, thanhtungtnt Video List Manager. This flaw is a specific type of code injection attack, known as SQL Injection, which could allow adversaries to manipulate the software’s database queries. This vulnerability is particularly concerning due to the potential for system compromise or data leakage, which could lead to unauthorized access to sensitive data or even entire system control. Given the widespread use of the Video List Manager in various sectors, this vulnerability has broad implications for data protection and system integrity.

How the Exploit Works
The SQL Injection vulnerability in thanhtungtnt Video List Manager occurs due to improper neutralization of special elements used in an SQL command. This allows an attacker to inject their own malicious SQL code into the database queries made by the software. By doing so, they can manipulate these queries to reveal sensitive data, modify or delete information, or even execute administrative operations on the database.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. An attacker sends a malformed request to the vulnerable endpoint, containing a malicious SQL command. This command is then inadvertently executed by the system, leading to unauthorized actions.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "' OR '1'='1'; DROP TABLE users; --" }In this example, the SQL command `OR ‘1’=’1’` is always true, potentially allowing the attacker to bypass authentication mechanisms. The `DROP TABLE users` command would delete the entire user database, while the `–` comments out any remaining SQL, preventing syntax errors.
Mitigation Strategies
The primary mitigation strategy for CVE-2025-52821 is to apply the vendor-provided patch. This should fix the underlying issue and prevent future exploitation. In case the patch cannot be immediately applied, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can help detect and block SQL Injection attempts as a temporary mitigation measure. However, these are not long-term solutions, and the patch should be applied as soon as practicable to fully secure your systems.
