CVE-2025-55167

Comprehensive Technical Analysis of CVE-2025-55167

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-55167 CVSS Score: 9.8

The CVSS score of 9.8 indicates that this vulnerability is critical. The high score is justified by the potential for attackers to execute arbitrary SQL commands, which can lead to full compromise of the database. This includes unauthorized access to sensitive data, modification or deletion of data, and potential denial of service.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: The primary attack vector is SQL injection through the id_dependente parameter in the /html/funcionario/dependente_remover.php endpoint. Attackers can craft malicious SQL queries to manipulate the database.

Exploitation Methods:

• Manual Exploitation: An attacker can manually input SQL commands into the id_dependente parameter to extract data, modify records, or delete information.
• Automated Tools: Attackers may use automated SQL injection tools to exploit the vulnerability more efficiently.

3. Affected Systems and Software Versions

Affected Software:

• WeGIA web manager versions prior to 3.4.8.

Systems:

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

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Upgrade to WeGIA version 3.4.8 or later, which includes the patch for this vulnerability.
• Input Validation: Implement strict input validation and sanitization for all user inputs, especially for parameters used in SQL queries.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.

Long-Term Strategies:

• Regular Updates: Ensure that all software components are regularly updated to the latest versions.
• Security Audits: Conduct regular security audits and code reviews to identify and mitigate potential vulnerabilities.
• Web Application Firewalls (WAF): Deploy WAFs to monitor and block malicious traffic.

5. Impact on Cybersecurity Landscape

Immediate Impact:

• Organizations using WeGIA are at high risk of data breaches, data manipulation, and service disruptions.
• The vulnerability can be exploited to gain unauthorized access to sensitive information, leading to potential legal and financial repercussions.

Long-Term Impact:

• Increased awareness of the importance of input validation and secure coding practices.
• Potential for similar vulnerabilities to be discovered in other open-source projects, highlighting the need for continuous security assessments.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: /html/funcionario/dependente_remover.php
• Parameter: id_dependente
• Vulnerability Type: SQL Injection

Exploitation Example: An attacker could send a request like:

/html/funcionario/dependente_remover.php?id_dependente=1 OR 1=1

This would result in the SQL query:

SELECT * FROM dependente WHERE id_dependente = 1 OR 1=1;

This query would return all records from the dependente table, potentially exposing sensitive data.

Patch Information:

• The vulnerability has been patched in WeGIA version 3.4.8. The patch includes proper input validation and the use of parameterized queries to prevent SQL injection.
