CVE-2025-52821 is a high-severity SQL Injection vulnerability (CWE-89) found in the thanhtungtnt Video List Manager software, affecting all versions up to and including 1.7. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing an attacker with low privileges (PR:L) to inject malicious SQL code remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality (C:H) with a limited impact on availability (A:L) and no impact on integrity (I:N). The scope is changed (S:C), indicating that the vulnerability can affect resources beyond the initially vulnerable component. Exploitation could allow an attacker to extract sensitive data from the backend database, potentially exposing user information or internal application data. Although no known exploits are currently in the wild, the ease of exploitation combined with the high CVSS score (8.5) suggests that this vulnerability poses a significant risk. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability is typical of SQL Injection flaws where input validation and parameterized queries are insufficient or absent, enabling attackers to manipulate SQL queries executed by the application.

For European organizations using thanhtungtnt Video List Manager, this vulnerability could lead to unauthorized disclosure of sensitive data stored in backend databases, including user credentials, personal data, or proprietary information. Given the high confidentiality impact, organizations handling regulated data under GDPR could face compliance violations and significant fines if breaches occur. The limited availability impact means service disruption is less likely but cannot be ruled out if attackers leverage the vulnerability for denial-of-service attacks. The scope change indicates that exploitation could affect other components or services connected to the vulnerable application, potentially broadening the attack surface. Organizations in sectors such as media, entertainment, education, or any industry relying on video content management may be particularly affected. The absence of known exploits currently provides a window for proactive defense, but the vulnerability's characteristics make it a likely target for attackers seeking to leverage SQL Injection for data exfiltration or lateral movement within networks.

1. Immediate mitigation should focus on implementing strict input validation and sanitization for all user-supplied data interacting with SQL queries within the Video List Manager application. 2. Employ parameterized queries or prepared statements to prevent injection of malicious SQL code. 3. Restrict database user permissions to the minimum necessary, avoiding use of high-privilege accounts for application database connections. 4. Monitor application logs and database query logs for unusual or suspicious activity indicative of SQL Injection attempts. 5. If possible, isolate the Video List Manager application within a segmented network zone to limit lateral movement in case of compromise. 6. Engage with the vendor or community to obtain or develop patches addressing this vulnerability promptly. 7. Conduct thorough code reviews and security testing (including automated SQL Injection scanning) on the application to identify and remediate similar vulnerabilities. 8. Implement Web Application Firewalls (WAFs) with rules tailored to detect and block SQL Injection payloads targeting this application. 9. Educate developers and administrators on secure coding practices and the risks associated with SQL Injection vulnerabilities. 10. Prepare incident response plans specifically addressing potential data breaches resulting from SQL Injection attacks.
