CVE-2025-6308: Emergency Ambulance Hiring Portal SQLi Flaw

CVE-2025-6308 Overview

CVE-2025-6308 is a SQL injection vulnerability in PHPGurukul Emergency Ambulance Hiring Portal 1.0. The flaw exists in the /admin/bwdates-request-report-details.php script, where the fromdate and todate parameters are passed into a database query without proper sanitization. An authenticated attacker with low privileges can manipulate these arguments to inject arbitrary SQL statements. The attack is exploitable remotely over the network, and the exploit has been publicly disclosed. The weakness is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact

Authenticated attackers can inject arbitrary SQL into the date range report query, exposing or modifying admin portal data.

Technical Details for CVE-2025-6308

Vulnerability Analysis

The vulnerability resides in the administrative reporting page bwdates-request-report-details.php. This script accepts two user-supplied parameters, fromdate and todate, that are used to build a date-range SQL query against the back-end MySQL database. Because the input is concatenated directly into the query string, an attacker can break out of the intended date literal and append arbitrary SQL clauses.

Successful exploitation allows extraction of records such as ambulance bookings, user information, and administrator credentials. Depending on database privileges, an attacker may also modify or delete portal data. The reporting endpoint sits behind admin authentication, so exploitation requires valid low-privilege admin credentials, which limits the attack surface relative to unauthenticated SQL injection flaws.

Root Cause

The root cause is the absence of parameterized queries and input validation in the report generation logic. The fromdate and todate request parameters are interpolated into a SQL BETWEEN clause without type checks or escaping. PHP's mysqli prepared statements are not used, and no allowlist constrains the input format to a valid date.

Attack Vector

An attacker authenticated to the admin portal submits a crafted POST or GET request to /admin/bwdates-request-report-details.php with malicious SQL payloads in the fromdate or todate fields. Common payloads use UNION SELECT to enumerate tables, time-based blind techniques such as SLEEP() to confirm injection, or boolean conditions to exfiltrate data character by character. No code example is included here because no verified proof-of-concept has been published; see the GitHub Issue Discussion for technical context.

Detection Methods for CVE-2025-6308

Indicators of Compromise

• Web server access logs containing requests to /admin/bwdates-request-report-details.php with SQL metacharacters such as ', --, UNION, or SLEEP( in the fromdate or todate parameters.
• Unusual MySQL error messages or extended query response times originating from the ambulance portal application user.
• Unexpected administrative-session activity outside normal business hours targeting the reporting endpoint.

Detection Strategies

• Deploy web application firewall (WAF) signatures that flag SQL injection patterns in fromdate and todate query strings.
• Enable MySQL general query logging and alert on queries from the application user that contain UNION SELECT, INFORMATION_SCHEMA, or stacked statements.
• Correlate authenticated admin sessions with anomalous parameter values using SIEM or data lake analytics.

Monitoring Recommendations

• Monitor the bwdates-request-report-details.php endpoint for elevated request volume from a single session.
• Track outbound database connections and row counts returned to the application to detect bulk data extraction.
• Audit admin account logins for brute-force or credential-stuffing activity that could grant the prerequisite low-privilege access.

How to Mitigate CVE-2025-6308

Immediate Actions Required

• Restrict access to /admin/ via IP allowlist or VPN until a fix is applied.
• Rotate all administrator credentials and enforce strong, unique passwords.
• Review the database for unauthorized records, modified rows, or new admin accounts.
• Enable WAF rules to block SQL injection payloads targeting the affected parameters.

Patch Information

PHPGurukul has not published a vendor advisory or patched release for CVE-2025-6308 at the time of NVD publication. Refer to the PHP Gurukul Homepage and the VulDB entry #313308 for status updates. Organizations using this portal in production should consider replacing the affected code path with parameterized queries or migrating away from the unmaintained version.

Workarounds

• Modify bwdates-request-report-details.php to use mysqli or PDO prepared statements with bound fromdate and todate parameters.
• Add server-side input validation that rejects any value not matching a strict YYYY-MM-DD regular expression.
• Apply the principle of least privilege to the database account used by the application, removing DROP, ALTER, and write permissions where not required.
• Place the admin portal behind multi-factor authentication to reduce the risk of credential compromise enabling exploitation.
