CVE-2026-28501

Comprehensive Technical Analysis of CVE-2026-28501

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2026-28501 CVSS Score: 9.8

The vulnerability in question is an unauthenticated SQL Injection flaw in WWBN AVideo, an open-source video platform. The issue arises due to improper sanitization of the catName parameter in JSON-formatted POST request bodies within the objects/videos.json.php and objects/video.php components. This vulnerability allows an attacker to inject malicious SQL code, potentially leading to unauthorized access, data manipulation, or data exfiltration.

The CVSS score of 9.8 indicates a critical severity level, reflecting the high impact and ease of exploitation. The vulnerability can be exploited without authentication, making it particularly dangerous.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated SQL Injection: An attacker can send a specially crafted JSON-formatted POST request to the vulnerable endpoints (objects/videos.json.php and objects/video.php). The catName parameter is not properly sanitized, allowing SQL injection.
• Automated Exploitation: Given the unauthenticated nature, automated scripts or bots can be used to exploit this vulnerability en masse.

Exploitation Methods:

• Data Exfiltration: Attackers can extract sensitive information from the database, including user credentials, video metadata, and other stored data.
• Data Manipulation: Attackers can alter database entries, leading to integrity issues.
• Unauthorized Access: Attackers can gain unauthorized access to the application, potentially leading to further exploitation.

3. Affected Systems and Software Versions

Affected Software:

• WWBN AVideo versions prior to 24.0.

Affected Components:

• objects/videos.json.php
• objects/video.php

Affected Systems:

• Any system running the vulnerable versions of WWBN AVideo, including web servers hosting the application.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade: Immediately upgrade to WWBN AVideo version 24.0 or later, which includes the patch for this vulnerability.
• Temporary Mitigation: Implement a Web Application Firewall (WAF) to block suspicious SQL injection attempts targeting the catName parameter.

Long-Term Strategies:

• Input Validation: Ensure all user inputs are properly sanitized and validated.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
• Monitoring: Implement monitoring and alerting for suspicious activities related to SQL injection attempts.

5. Impact on Cybersecurity Landscape

The discovery and exploitation of this vulnerability highlight the ongoing challenges in securing web applications, particularly those that handle user inputs. The high CVSS score underscores the critical nature of SQL injection vulnerabilities and the need for robust input validation and sanitization practices.

This incident serves as a reminder for organizations to prioritize security in their software development lifecycle (SDLC) and to stay vigilant about patching and updating their applications promptly.

6. Technical Details for Security Professionals

Vulnerability Details:

• Vulnerable Parameter: catName
• Vulnerable Endpoints: objects/videos.json.php and objects/video.php
• Exploitation Method: JSON-formatted POST request with malicious SQL payload in the catName parameter.

Example Exploit:

{
  "catName": "' OR '1'='1"
}

Patch Details:

• The vulnerability has been addressed in WWBN AVideo version 24.0. The patch ensures proper sanitization of the catName parameter and prevents SQL injection.
