CVE-2025-4304: Cyber Cafe Management System SQLi Flaw

CVE-2025-4304 Overview

CVE-2025-4304 is a SQL injection vulnerability in PHPGurukul Cyber Cafe Management System 1.0. The flaw resides in the /adminprofile.php script, where the mobilenumber parameter is passed to a backend SQL query without proper sanitization. Attackers can manipulate this parameter to inject arbitrary SQL statements remotely, without authentication or user interaction. The vendor advisory notes that additional parameters in the same file may also be affected. Public disclosure of the exploit technique has occurred, increasing the likelihood of opportunistic attacks against exposed installations. The vulnerability is tracked under [CWE-89] (SQL Injection) and [CWE-74] (Improper Neutralization of Special Elements in Output).

Critical Impact
Unauthenticated remote attackers can execute arbitrary SQL queries against the application database through the mobilenumber parameter in /adminprofile.php, potentially exposing or modifying stored data.

Affected Products

Technical Details for CVE-2025-4304

Vulnerability Analysis

The vulnerability allows remote attackers to inject SQL syntax into the mobilenumber HTTP parameter processed by /adminprofile.php. The application concatenates user-controlled input directly into a SQL statement without parameterized queries or input validation. An attacker submits a crafted POST or GET request containing SQL metacharacters in the mobilenumber field, and the backend database executes the injected payload as part of the original query. Successful exploitation can lead to disclosure of administrator credentials, modification of customer and session records, and authentication bypass through query manipulation. According to the VulDB submission, other parameters in the same script likely share the same flaw, broadening the attack surface.

Root Cause

The root cause is improper neutralization of special elements used in an SQL command [CWE-89]. The mobilenumber value is interpolated into the SQL query string rather than bound through a prepared statement. PHPGurukul applications historically rely on direct concatenation with mysqli_query() style calls, which exposes every untrusted input field to injection when not explicitly escaped.

Attack Vector

The attack is network-based and requires no privileges or user interaction. An attacker sends a single HTTP request to the administrator profile endpoint with a malicious mobilenumber payload. Because /adminprofile.php is an administrative page, exploitation typically requires reaching a session boundary, but the injection itself is reachable when the page is exposed without strict access controls. Public proof-of-concept details are available through the GitHub Issue Tracker and VulDB #307407.

Detection Methods for CVE-2025-4304

Indicators of Compromise

HTTP requests to /adminprofile.php containing SQL metacharacters such as single quotes, UNION SELECT, --, OR 1=1, or SLEEP( in the mobilenumber parameter.
Unexpected database errors logged by MySQL or PHP referencing adminprofile.php.
Outbound database reads of unusually large result sets correlated with traffic to the admin module.
Creation or modification of administrator accounts that does not align with legitimate operator activity.

Detection Strategies

Deploy web application firewall rules that flag SQL syntax in non-numeric parameters, especially mobilenumber.
Enable verbose query logging on the database and alert on syntactically anomalous statements originating from the application user.
Review web server access logs for repeated requests to /adminprofile.php from the same source with varying payloads, a pattern typical of automated SQLi tools such as sqlmap.

Monitoring Recommendations

Forward web server, PHP error, and MySQL general query logs to a centralized analytics platform for correlation.
Baseline normal admin module usage and alert on off-hours or high-volume access attempts.
Track changes to administrative tables and trigger alerts on schema enumeration queries against information_schema.

How to Mitigate CVE-2025-4304

Immediate Actions Required

Restrict access to /adminprofile.php through network ACLs, VPN, or IP allowlists until a fix is applied.
Place the application behind a web application firewall with SQL injection signatures enabled.
Audit administrator accounts and rotate credentials, assuming compromise if the application has been internet-exposed.
Review database logs for evidence of prior exploitation against the mobilenumber parameter.

Patch Information

No official vendor patch has been published in the referenced advisories at the time of NVD publication. Operators should monitor the PHP Gurukul Blog and the VulDB advisory for updates. Until a patch is released, application owners should apply code-level fixes by replacing concatenated SQL with parameterized queries using mysqli_prepare() or PDO prepared statements, and by validating that mobilenumber contains only digits.

Workarounds

Modify /adminprofile.php locally to bind the mobilenumber parameter through a prepared statement instead of string concatenation.
Apply server-side input validation that rejects any mobilenumber value containing non-numeric characters.
Disable or remove the Cyber Cafe Management System 1.0 instance if it is not actively required, given the public disclosure of exploit details.
Enforce least-privilege database accounts so the application user cannot read system tables or write outside required schemas.

bash

# Example: restrict access to the vulnerable admin endpoint via Apache
<Location "/adminprofile.php">
    Require ip 10.0.0.0/8
    Require ip 192.168.0.0/16
</Location>
