The vulnerability is located in the endpoint /WeGIA/html/funcionario/remuneracao.php and involves the id_funcionario parameter. This vulnerability allows an attacker to execute arbitrary SQL commands, which can lead to unauthorized access, data manipulation, and potential data loss.

Severity Evaluation:

• Base Score: 10.0 (Critical)
• Base Score Version: 4.0
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H

The CVSS score of 10.0 indicates a critical vulnerability due to the high impact on confidentiality, integrity, and availability, as well as the ease of exploitation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: An attacker can inject malicious SQL code into the id_funcionario parameter to manipulate the database.
• Data Exfiltration: Attackers can extract sensitive information from the database.
• Data Manipulation: Attackers can alter or delete data, compromising data integrity.
• Unauthorized Access: Attackers can gain unauthorized access to the database, potentially leading to further attacks.

Exploitation Methods:

• Manual Exploitation: Crafting specific SQL queries to exploit the vulnerability.
• Automated Tools: Using automated SQL injection tools to identify and exploit the vulnerability.
• Phishing: Tricking users into visiting a malicious site that exploits the vulnerability.

3. Affected Systems and Software Versions

Affected Systems:

• WeGIA Web manager versions prior to 3.2.8.

Software Versions:

• All versions of WeGIA before 3.2.8 are vulnerable.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade: Upgrade to WeGIA version 3.2.8 or later, which includes the fix for this vulnerability.
• Patch Management: Ensure that all systems are regularly updated and patched.

Long-Term Mitigation:

• Input Validation: Implement strict input validation and sanitization for all user inputs.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewall (WAF): Deploy a WAF to detect and block SQL injection attempts.
• Regular Audits: Conduct regular security audits and vulnerability assessments.

5. Impact on European Cybersecurity Landscape

The vulnerability in WeGIA, a Web manager used by charitable institutions, poses a significant risk to the European cybersecurity landscape. Charitable institutions often handle sensitive data, including personal information of donors and beneficiaries. A successful exploitation of this vulnerability could lead to data breaches, financial losses, and reputational damage for these institutions.

Given the critical nature of the vulnerability and its potential impact, it is essential for organizations using WeGIA to prioritize patching and implementing robust security measures to protect against such threats.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: /WeGIA/html/funcionario/remuneracao.php
• Parameter: id_funcionario
• Vulnerability Type: SQL Injection

Exploitation Example: An attacker could inject a malicious SQL query into the id_funcionario parameter, such as:

id_funcionario=1'; DROP TABLE users; --

This query would delete the users table, demonstrating the potential for data loss and unauthorized access.

Detection Methods:

• Log Analysis: Monitor database logs for unusual SQL queries.
• Intrusion Detection Systems (IDS): Use IDS to detect and alert on suspicious activities.
• Code Review: Conduct a thorough code review to identify and fix similar vulnerabilities.
