The vulnerability is a classic SQL injection in the `per_id` parameter of the `/view_personnel.php` file. This parameter is directly concatenated into a database query without proper sanitization or the use of prepared statements. An attacker can send a specially crafted value to this parameter, causing the backend database to interpret part of the input as a SQL command rather than simple data. This manipulation alters the original query’s logic. Since the attack can be launched remotely and only requires a low-privilege account, an attacker can exploit this to read, modify, or delete sensitive data within the database, such as employee personal information, salaries, or system credentials. The vulnerability has a public exploit, increasing the risk of automated attacks.

What Undercode Say
Bash Commands and Code:
Probing the vulnerable parameter curl -s "http://target.com/view_personnel.php?per_id=1" | grep -i error Testing with a basic SQL injection payload curl -s "http://target.com/view_personnel.php?per_id=1' OR '1'='1" Using sqlmap for automated exploitation sqlmap -u "http://target.com/view_personnel.php?per_id=1" --batch --dbs
// Example of vulnerable code pattern in view_personnel.php $per_id = $_GET['per_id']; $query = "SELECT FROM personnel WHERE id = '" . $per_id . "'"; // User input in $per_id is directly concatenated into the SQL string.
How Exploit
An attacker identifies the injectable `per_id` parameter. They then submit payloads like `1′ AND ‘1’=’1` to confirm vulnerability. Using UNION-based attacks, they can extract data from other database tables. Alternatively, time-based blind injection payloads (e.g., 1' AND SLEEP(5)--) can be used to infer data when results are not directly visible. Public exploit scripts may automate this process to dump the entire database.
Protection from this CVE
Immediately apply vendor patch. Implement strict input validation, rejecting unexpected characters. Use parameterized queries (prepared statements) to separate code from data. Deploy a Web Application Firewall (WAF) with SQL injection rules. Enforce the principle of least privilege on the database account used by the application.
Impact
Unauthorized access to all employee records. Potential for complete database compromise. Data breach leading to privacy violations and regulatory fines. Possible initial foothold for further network attacks.
