• UI:N (No User Interaction): No user interaction is required for the attack to succeed.
• VC:H (High Confidentiality Impact): The vulnerability can lead to a complete compromise of confidentiality.
• VI:H (High Integrity Impact): The vulnerability can lead to a complete compromise of integrity.
• VA:H (High Availability Impact): The vulnerability can lead to a complete compromise of availability.
• SC:H (High Scope Change): The vulnerability can affect other components beyond the initial scope.
• SI:H (High Impact on Scope): The impact on the scope is significant.
• SA:H (High Attack Vector): The attack vector is highly effective.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: Attackers can inject malicious SQL queries through the adicionar_cor.php endpoint.
• Database Dump: Exploiting the vulnerability can result in a complete dump of the application's database, exposing sensitive information.

Exploitation Methods:

• Manual SQL Injection: Attackers can manually craft SQL queries to extract data or manipulate the database.
• Automated Tools: Use of automated SQL injection tools to identify and exploit the vulnerability.
• Stored Procedures: Execution of stored procedures to gain unauthorized access or modify data.

3. Affected Systems and Software Versions

Affected Systems:

• WeGIA application versions prior to 3.2.10.

Software Versions:

• All versions of WeGIA before 3.2.10 are vulnerable to this SQL Injection flaw.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade: Upgrade to WeGIA version 3.2.10 or later, which includes the fix for this vulnerability.
• Patch: Apply the security patch provided in the GitHub commit ae9c859006143bd0087b3e6e48a0677e1fff5c7e.
