code-projects Project Management System SQL Injection Vulnerability (CVE-2026-9584)

A SQL injection vulnerability, identified as CVE-2026-9584, has been discovered in code-projects Project Management System version 1.0. The vulnerability is located in the chk.php file within the Login component. This flaw allows a remote attacker to inject arbitrary SQL commands into the application’s database queries, potentially leading to unauthorized data access, modification, or deletion. The exploit is publicly disclosed, making it more likely to be exploited. This vulnerability poses a significant risk to organizations using the affected software, potentially compromising sensitive project data and system integrity.

Attack Chain

1. The attacker identifies a publicly accessible chk.php file within the Project Management System 1.0.
2. The attacker crafts a malicious HTTP request targeting the chk.php endpoint.
3. The HTTP request includes specially crafted SQL injection payloads within the input parameters.
4. The application fails to properly sanitize the input, passing the malicious SQL query to the database.
5. The database executes the injected SQL commands, allowing the attacker to bypass authentication.
6. The attacker gains unauthorized access to the application’s database.
7. The attacker extracts sensitive information, such as usernames, passwords, or project data.
8. The attacker may further manipulate the database, modifying or deleting data, or escalating privileges.

Impact

Successful exploitation of this vulnerability can lead to complete compromise of the Project Management System’s database. An attacker could gain access to sensitive project information, customer data, and internal credentials. The number of affected victims depends on the deployment size of Project Management System 1.0. This can lead to data breaches, financial losses, and reputational damage.

Recommendation

• Apply the Sigma rule Detect CVE-2026-9584 Exploitation Attempt via HTTP Request to detect suspicious HTTP requests targeting the affected chk.php file.
• Implement proper input validation and sanitization techniques to prevent SQL injection attacks in the chk.php file.
• Upgrade to a patched version of code-projects Project Management System or implement a web application firewall (WAF) rule to mitigate the vulnerability.
• Monitor web server logs for suspicious activity related to SQL injection attempts, as detected by the Detect CVE-2026-9584 Successful SQL Injection Sigma rule.
