CVE-2025-5693: hMPV Testing Management System SQL Injection

CVE-2025-5693 Overview

CVE-2025-5693 is a SQL injection vulnerability in PHPGurukul Human Metapneumovirus (HMPV) Testing Management System 1.0. The flaw resides in the /bwdates-report-result.php script, where the fromdate and todate request parameters are concatenated into a SQL query without proper sanitization. An attacker with low-privilege access can send crafted HTTP requests to manipulate the underlying database query. The exploit details have been disclosed publicly, increasing the risk of opportunistic exploitation against unpatched deployments. The issue is tracked under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component.

Critical Impact
Remote authenticated attackers can read, modify, or destroy database records by injecting SQL through the fromdate and todate parameters of the date-range report function.

Technical Details for CVE-2025-5693

Vulnerability Analysis

The vulnerability is a classic SQL injection in the date-range report functionality of the HMPV Testing Management System. The bwdates-report-result.php endpoint accepts user-controlled fromdate and todate values and embeds them directly into a SQL statement used to filter test records. Because the application does not apply parameterized queries or input validation, an attacker can break out of the intended date literal and append arbitrary SQL clauses. Successful exploitation allows extraction of sensitive patient and administrative data, manipulation of stored records, or authentication bypass through query logic tampering.

Root Cause

The root cause is improper neutralization of special elements within a SQL statement [CWE-74]. The application concatenates request parameters into a query string instead of binding them as parameters, allowing SQL metacharacters such as single quotes and UNION clauses to alter the query structure. No server-side type validation is performed on the date values before they reach the database layer.

Attack Vector

The attack is remote and requires only low-level privileges to reach the report endpoint. An attacker submits a crafted POST or GET request to /bwdates-report-result.php containing SQL payloads in the fromdate or todate fields. Typical exploitation uses UNION SELECT statements to exfiltrate data or boolean-based blind injection to enumerate the schema. See the GitHub Issue Discussion and VulDB entry #311209 for additional technical context.

Detection Methods for CVE-2025-5693

Indicators of Compromise

HTTP requests to /bwdates-report-result.php containing SQL keywords such as UNION, SELECT, SLEEP, --, or 0x in the fromdate or todate parameters.
Unusually long parameter values or encoded single quotes (%27) in date fields that should contain ISO date strings.
Database error messages returned to clients referencing MySQL syntax errors originating from the report query.
Anomalous outbound traffic from the web server following report-page activity, indicating possible data exfiltration.

Detection Strategies

Deploy web application firewall (WAF) rules that validate date-formatted parameters and reject non-date characters on the /bwdates-report-result.php endpoint.
Enable database query logging and alert on multi-statement queries or queries containing UNION operations originating from the HMPV application user.
Correlate web access logs with database audit logs to identify request-to-query patterns indicative of injection attempts.

Monitoring Recommendations

Monitor authentication logs for low-privileged accounts accessing the reporting module outside normal working hours.
Track row-count anomalies for queries returning unusually large result sets from the test-records table.
Continuously baseline traffic to bwdates-report-result.php and alert on volumetric spikes consistent with automated scanning or sqlmap-style probing.

How to Mitigate CVE-2025-5693

Immediate Actions Required

Restrict access to the HMPV Testing Management System to trusted networks or VPN clients until a patched version is available.
Place a WAF in front of the application with rules enforcing strict date format validation (YYYY-MM-DD) on the fromdate and todate parameters.
Review database accounts used by the application and revoke unnecessary privileges such as FILE, DROP, or cross-database access.
Audit recent application and database logs for signs of prior exploitation.

Patch Information

At the time of writing, no vendor patch has been published for PHPGurukul Human Metapneumovirus (HMPV) Testing Management System 1.0. Refer to the PHP Gurukul Homepage and the VulDB advisory for updates. Until an official fix is released, organizations should consider taking the application offline or replacing it with a maintained alternative.

Workarounds

Modify bwdates-report-result.php locally to use prepared statements with bound parameters via PHP Data Objects (PDO) or mysqli parameterized queries.
Add server-side validation that rejects any fromdate or todate value not matching a strict date regular expression before query construction.
Apply the principle of least privilege to the database user account, granting only SELECT on the specific tables required by the reporting feature.
Disable verbose database error reporting in production to prevent attackers from leveraging error-based injection techniques.
