Listen to this Post
The vulnerability, identified as CVE-2026-3765, resides in the itsourcecode University Management System version 1.0, specifically within the file `/att_single_view.php` . The issue stems from the application’s failure to properly sanitize user-supplied input before using it in a SQL query. An attacker can manipulate the `dt` argument passed to this script via an HTTP request . By injecting malicious SQL code into the `dt` parameter, the attacker can alter the intended database query’s structure. This allows for the unauthorized retrieval of data from the database, including sensitive information like user credentials or personal records. The attack vector is network-based, requiring no authentication or user interaction, as indicated by the CVSS vector (PR:N/UI:N) . The exploit for this vulnerability has been publicly released, increasing the risk of widespread automated attacks against unpatched systems . The technical impact is a partial loss of confidentiality, integrity, and availability .

What Undercode Say:
Analysis
The CVE details confirm a classic unauthenticated SQL injection in a PHP application . The presence of a public exploit ( references a GitHub issue) significantly elevates the risk. The attack surface is limited to a single script, making detection and patching straightforward for administrators, but the window of opportunity for attackers is wide given the public disclosure.
Exploit
The exploit targets the `dt` parameter. A basic injection payload would attempt to break the original query context and append malicious SQL.
Example using curl to test for vulnerability Replace [target-url] with the actual base URL of the application curl -g "[target-url]/att_single_view.php?dt=1'%20OR%20'1'%3D'1"
A more aggressive proof-of-concept might attempt to extract data:
-- Example payload to extract usernames and passwords from a hypothetical users table 1' UNION SELECT 1, username, password, 4 FROM users --
Protection
Immediate protection relies on input validation and escaping.
// Insecure code (vulnerable)
$dt = $_GET['dt'];
$query = "SELECT FROM attendance WHERE date = '$dt'";
// Secure code using parameterized queries (mysqli)
$stmt = $conn->prepare("SELECT FROM attendance WHERE date = ?");
$stmt->bind_param("s", $_GET['dt']);
$stmt->execute();
The only reliable fix is to use parameterized queries or prepared statements, which separate SQL logic from data. Input filtering alone is often insufficient.
Impact
Unauthenticated attackers can read, modify, or delete all data within the University Management System’s database. This leads to complete compromise of student and staff records, potential defacement of the application, and lateral movement if database credentials are reused.
