CVE-2024-33288: Prison Management System PHP SQLi Flaw

CVE-2024-33288 Overview

CVE-2024-33288 is a SQL injection vulnerability [CWE-89] affecting Prison Management System Using PHP v1.0, a web application distributed through SourceCodester. The flaw resides in the username parameter on the Admin login page. An unauthenticated remote attacker can inject malicious SQL statements into the login request to manipulate the underlying database query.

Successful exploitation allows attackers to bypass authentication, read or modify database records, and gain administrative access to the application. A public proof-of-concept is available through Exploit-DB, which lowers the barrier to exploitation.

Critical Impact

Unauthenticated attackers can bypass authentication on the Admin login page and access prisoner records, staff data, and administrative functionality through crafted SQL payloads in the username field.

Affected Products

• Prison Management System Using PHP v1.0 (SourceCodester)
• Admin login component (username parameter)
• Deployments using the unpatched upstream source code

Technical Details for CVE-2024-33288

Vulnerability Analysis

The vulnerability is a classic SQL injection [CWE-89] in the administrator authentication flow of Prison Management System v1.0. The application accepts the username value from the login form and concatenates it directly into a SQL query executed against the backend database. Because no parameterized queries or input sanitization are applied, attacker-supplied SQL syntax becomes part of the executed statement.

The attack vector is the network, requires no privileges, and needs no user interaction. An attacker only needs reachability to the application's login page to attempt exploitation. According to EPSS data from 2026-05-18, the probability of observed exploitation is low, but a working exploit is publicly indexed on Exploit-DB as entry #52017.

Root Cause

The root cause is improper neutralization of special elements used in a SQL command. The login handler builds its query through string concatenation of the submitted username value rather than using prepared statements with bound parameters. PHP's mysqli or PDO parameterized APIs are not used to isolate user input from SQL syntax.

Attack Vector

An attacker submits a crafted payload in the username field of the Admin login form. Common payloads use a single quote to break out of the SQL string literal, followed by boolean tautologies such as OR 1=1 and a comment marker to discard the trailing portion of the original query. This causes the authentication check to return a truthy result, granting administrative access without valid credentials.

Attackers can also leverage UNION-based or time-based blind techniques to extract database contents, including credential hashes for other accounts. Refer to the Exploit-DB #52017 entry for the published proof-of-concept request structure.

Detection Methods for CVE-2024-33288

Indicators of Compromise

• HTTP POST requests to the Admin login endpoint containing SQL metacharacters such as ', --, #, UNION, or OR 1=1 in the username field.
• Unexpected successful administrator logins originating from unfamiliar IP addresses or geographies.
• Database error messages or 500 responses returned from the login page during reconnaissance attempts.
• Spikes in failed or malformed login submissions targeting the /admin/ path of the Prison Management System.

Detection Strategies

• Deploy web application firewall (WAF) rules that inspect login form parameters for SQL injection signatures and known payloads from Exploit-DB #52017.
• Enable verbose query logging on the backend MySQL instance and alert on queries containing tautologies or comment markers originating from the application user.
• Correlate web server access logs with database audit logs to identify authentication events triggered by anomalous query patterns.

Monitoring Recommendations

• Monitor for new administrator sessions created without a corresponding valid credential validation event in application logs.
• Track outbound data volume from the database server to detect bulk extraction following a successful injection.
• Alert on schema enumeration queries such as access to information_schema.tables or information_schema.columns from the web application account.

How to Mitigate CVE-2024-33288

Immediate Actions Required

• Restrict network access to the Prison Management System Admin login page using IP allow-listing or VPN gating until code-level fixes are deployed.
• Audit recent database and authentication logs for evidence of SQL injection attempts or unauthorized administrator logins.
• Rotate all administrator and database credentials, and review user tables for unauthorized accounts.

Patch Information

No official vendor patch is listed in the NVD entry at the time of publication. The application is distributed as open-source PHP code through SourceCodester. Operators must remediate at the source level by replacing vulnerable query construction with parameterized statements using PDO::prepare() or mysqli_prepare() and binding the username and password values. Server-side input validation should reject non-alphanumeric characters in the username field. Review the SourceCodester project page for any updated releases.

Workarounds

• Place the application behind a WAF configured with OWASP Core Rule Set SQL injection signatures in blocking mode.
• Apply database-layer least privilege by restricting the application's database user to the minimum tables and operations required.
• Disable the application or take it offline if it is exposed to untrusted networks and no remediation is available.

# Example PHP remediation: replace concatenated query with prepared statement
# Vulnerable pattern (do not use):
#   $sql = "SELECT * FROM admin WHERE username='".$_POST['username']."' AND password='".md5($_POST['password'])."'";
#
# Mitigation using PDO prepared statements:
$stmt = $pdo->prepare('SELECT id, username FROM admin WHERE username = :u AND password = :p');
$stmt->execute([
    ':u' => $_POST['username'],
    ':p' => hash('sha256', $_POST['password'])
]);
$user = $stmt->fetch(PDO::FETCH_ASSOC);
