This critical flaw affects an unknown functionality within the popular file share.php, and it has been classified as a high-priority issue. The issue arises due to a SQL injection vulnerability that arises from the manipulation of the 'post_id' argument. This vulnerability poses a significant risk, as attackers could potentially exploit this flaw to gain unauthorized access to sensitive data or compromise the affected systems.

2. CVE-2022-3789: Full Details of Tim Campus Confession Wall Vulnerability

Here is a sample code snippet demonstrating the vulnerable portion of the share.php file

// Vulnerable share.php portion
$post_id = $_GET['post_id'];
$sql = "SELECT * FROM confessions WHERE post_id = '$post_id';";
$result = mysqli_query($conn, $sql);

while ($row = mysqli_fetch_assoc($result)) {
    // Process and display data

In the code above, the 'post_id' parameter is being taken directly from user input without any validation, making it prone to SQL injection attacks.

Exploit Details

To exploit this vulnerability, an attacker would typically manipulate the 'post_id' variable by crafting a malicious request. For example, an attacker can send the following SQL injection payload:

post_id = '-1 UNION SELECT 1, username, password, 4, 5 FROM users -- '

If an attacker successfully executes this payload, it could potentially retrieve sensitive data or compromise the affected system.

Mitigation Steps

To mitigate this vulnerability, it is essential to perform proper input validation and sanitize user-supplied data before using it in any SQL query. One such solution involves using prepared statements, as shown in the example below:

// Safer code using prepared statements
$post_id = $_GET['post_id'];
$stmt = $conn->prepare("SELECT * FROM confessions WHERE post_id = ?");
$stmt->bind_param("i", $post_id);
$result = $stmt->get_result();

while ($row = $result->fetch_assoc()) {
    // Process and display data


The Tim Campus Confession Wall vulnerability, CVE-2022-3789, highlights the importance of securing web applications by using best practices and robust coding standards. It is crucial for developers and administrators to address this vulnerability promptly, keeping in mind the sensitive nature of the data and the potential consequences of successful exploitation.
