CVE-2025-53529

Comprehensive Technical Analysis of CVE-2025-53529

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-53529 CVSS Score: 9.8

The vulnerability in question is an SQL Injection flaw in the WeGIA web manager, specifically affecting the /html/funcionario/profile_funcionario.php endpoint. The id_funcionario parameter is not properly sanitized or validated, allowing an attacker to inject arbitrary SQL commands. The high CVSS score of 9.8 indicates a critical severity due to the potential for unauthenticated attackers to exploit the vulnerability, leading to significant impacts such as data breaches, data manipulation, and unauthorized access.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The vulnerability can be exploited without requiring authentication, making it accessible to a broader range of attackers.
• SQL Injection: By crafting malicious input for the id_funcionario parameter, an attacker can inject SQL commands that manipulate the database.

Exploitation Methods:

• Data Exfiltration: Attackers can extract sensitive information from the database, including user credentials, personal information, and financial data.
• Data Manipulation: Injecting SQL commands can alter database entries, leading to data integrity issues.
• Unauthorized Access: Attackers can gain unauthorized access to the database, potentially leading to further exploitation of the system.

3. Affected Systems and Software Versions

Affected Software:

• WeGIA web manager versions prior to 3.4.3.

Systems:

• Any system running the vulnerable versions of WeGIA, particularly those with the /html/funcionario/profile_funcionario.php endpoint exposed to the internet.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade to Version 3.4.3: Ensure all instances of WeGIA are updated to version 3.4.3, which includes the fix for this vulnerability.
• Input Validation and Sanitization: Implement robust input validation and sanitization mechanisms to prevent SQL injection attacks.
• Web Application Firewall (WAF): Deploy a WAF to monitor and block malicious SQL injection attempts.

Long-Term Strategies:

• Regular Security Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
• Security Training: Provide training for developers on secure coding practices, particularly focusing on SQL injection prevention.
• Patch Management: Establish a robust patch management process to ensure timely updates and patches are applied.

5. Impact on Cybersecurity Landscape

The discovery and exploitation of SQL injection vulnerabilities continue to be a significant concern in the cybersecurity landscape. This vulnerability highlights the importance of secure coding practices and the need for continuous monitoring and updating of web applications. The high CVSS score underscores the potential for severe impacts, including data breaches and unauthorized access, which can have far-reaching consequences for organizations and individuals.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: /html/funcionario/profile_funcionario.php
• Parameter: id_funcionario
• Issue: Lack of proper sanitization and validation of the id_funcionario parameter.

Exploitation Example: An attacker could craft a malicious URL such as:

http://example.com/html/funcionario/profile_funcionario.php?id_funcionario=1'; DROP TABLE users; --

This input could potentially drop the users table if the SQL query is not properly sanitized.

Mitigation Code Example: Ensure that all user inputs are properly sanitized using prepared statements or parameterized queries. For example, in PHP:

$stmt = $pdo->prepare('SELECT * FROM funcionarios WHERE id_funcionario = :id');
$stmt->execute(['id' => $id_funcionario]);
