CVE-2019-25726: SQL Injection in All in One Video Downloader 1.2 – HIGH Severity Vulnerability

Technical summary

CVE-2019-25726 is a UNION-based SQL injection vulnerability in the admin interface of All in One Video Downloader 1.2. The flaw exists in the id parameter, which fails to properly sanitize user input before incorporating it into SQL queries. Attackers can inject arbitrary SQL syntax to manipulate query logic, retrieve unauthorized data, or potentially modify database contents. The attack vector is network-based, requires no authentication, and has low attack complexity, making it trivially exploitable by automated scanners.

Business impact

This vulnerability exposes the application's entire database to unauthorized access, creating immediate risk of credential theft, user data exfiltration, and potential compliance violations (GDPR, HIPAA, PCI-DSS depending on stored data). If the application stores payment information, personal identifiers, or other sensitive user records, attackers can harvest and monetize that data. The reputational damage from a confirmed breach could exceed the technical remediation cost.

Affected systems

All in One Video Downloader version 1.2 is confirmed vulnerable. Organizations running this software should assume they are at risk. Patch availability and version compatibility should be verified directly with the vendor. If your organization has this application deployed—even on internal or staging systems—it should be treated as a priority remediation target.

Exploitability

Exploitation is straightforward and requires only HTTP client tools (curl, Burp Suite, or custom scripts). No authentication is needed, no user interaction is required, and the attack can be fully automated. Public awareness of the flaw may drive opportunistic scanning and exploitation attempts. The low barrier to entry means this vulnerability will likely see active exploitation if the affected software is internet-facing.

Remediation

Immediately upgrade All in One Video Downloader beyond version 1.2. Verify the patched version from the vendor's official advisory before deployment. If immediate patching is impossible, implement network segmentation to restrict access to the admin interface to trusted internal IPs only, and monitor database activity for suspicious queries. Additionally, run SQL injection detection and Web Application Firewall (WAF) rules to block common payloads until patching is complete.

Patch guidance

Contact the vendor or consult the official advisory to identify the patched version number and deployment method. Test the patch in a non-production environment first to confirm compatibility with your specific deployment. After patching, verify that the id parameter is now properly parameterized and that SQL injection payloads are rejected. Document the patch date and version for audit and compliance records.

Detection guidance

Monitor HTTP logs for requests to the admin interface containing SQL keywords (SELECT, UNION, WHERE, OR, AND) in the id parameter, especially those with unusual encodings or special characters. Enable database query logging to detect suspicious SELECT statements that retrieve multiple tables or extract system metadata. Deploy a WAF with SQL injection signatures to block malicious patterns before they reach the application. Query application logs for error messages indicating SQL syntax violations, which may signal active exploitation attempts.

Why prioritize this

This vulnerability scores 8.2 (HIGH) under CVSS 3.1 due to its high confidentiality impact, network-based attack vector, and complete lack of authentication requirements. While integrity impact is limited (attackers cannot easily modify data), the exposure of sensitive database contents poses immediate business and compliance risk. The ease of exploitation and remote nature elevate this above many other vulnerabilities and warrant urgent action.

Risk score, explained

The CVSS 3.1 score of 8.2 reflects: (1) Network attack vector—exploitable from anywhere without VPN or physical access; (2) No privileges required—unauthenticated exploitation; (3) No user interaction—fully automated attack; (4) High confidentiality impact—full database read access; (5) Low integrity impact—SQL injection can modify data but is not the primary threat vector; (6) No availability impact—DoS is not the primary concern. This combination places the vulnerability in the HIGH severity tier, demanding rapid remediation.
