CVE-2026-10253: House Rental System SQLi Vulnerability

CVE-2026-10253 Overview

CVE-2026-10253 is a SQL injection vulnerability in itsourcecode Online House Rental System version 1.0. The flaw resides in the /manage_payment.php script, where the ID parameter is concatenated into a database query without proper sanitization. Attackers can inject arbitrary SQL syntax through this parameter to manipulate backend queries. The issue is classified under [CWE-74] for improper neutralization of special elements in output used by a downstream component. The exploit has been disclosed publicly and can be triggered remotely without authentication or user interaction.

Critical Impact
Unauthenticated remote attackers can inject SQL statements through the ID parameter of /manage_payment.php, exposing or modifying rental records, payment data, and administrative credentials.

Affected Products

itsourcecode Online House Rental System 1.0
/manage_payment.php payment management endpoint
Backend MySQL database supporting the application

Technical Details for CVE-2026-10253

Vulnerability Analysis

The vulnerability exists in the manage_payment.php script of the Online House Rental System. The script accepts an ID argument through an HTTP request and incorporates the value directly into a SQL statement. Because the value is neither parameterized nor escaped, attackers can append SQL operators, UNION clauses, or stacked queries to alter the original statement.

Exploitation is achievable over the network with no privileges or user interaction. The vulnerability is mapped to [CWE-74], reflecting improper neutralization of special elements during query construction. The EPSS probability is 0.033% with a percentile of 10.197, indicating low predicted exploitation activity despite the public proof-of-concept.

The Online House Rental System handles tenant records, rental payments, and administrative accounts. A successful injection can disclose payment data, modify financial records, or extract password hashes used by administrative accounts.

Root Cause

The root cause is unsafe concatenation of the ID request parameter into a SQL query inside manage_payment.php. The application lacks prepared statements, parameterized queries, and input validation. Any string supplied by the client reaches the database engine as part of the query text.

Attack Vector

An unauthenticated remote attacker issues an HTTP request to /manage_payment.php with a crafted ID parameter. Standard SQL injection techniques apply, including boolean-based blind, time-based blind, error-based, and UNION-based extraction. Automated tools such as sqlmap can enumerate the database with minimal manual work.

The vulnerability manifests in the payment management handler. Refer to the GitHub Issue #5 and VulDB CVE-2026-10253 entry for technical details and proof-of-concept information.

Detection Methods for CVE-2026-10253

Indicators of Compromise

HTTP requests to /manage_payment.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the ID parameter.
Web server logs showing repeated requests to manage_payment.php with varying ID values and abnormal response sizes.
Database error messages referencing manage_payment.php queries in application or MySQL error logs.
Unexpected outbound database traffic or extended query execution times originating from the rental application backend.

Detection Strategies

Deploy web application firewall signatures that flag SQL injection patterns targeting the ID query parameter on PHP endpoints.
Enable MySQL general query logging temporarily to identify malformed statements originating from manage_payment.php.
Correlate HTTP 500 responses from /manage_payment.php with downstream database errors to surface injection attempts.

Monitoring Recommendations

Forward web server access logs and database logs to a centralized logging platform for query inspection.
Alert on UNION-based, time-based, and boolean-based injection signatures specific to MySQL syntax.
Track authentication anomalies against the administrative interface that may follow credential extraction.

How to Mitigate CVE-2026-10253

Immediate Actions Required

Restrict public access to /manage_payment.php through network controls or authentication checks until a fix is applied.
Deploy WAF rules that block SQL metacharacters in the ID parameter of the payment endpoint.
Rotate database credentials and administrative passwords if exploitation is suspected.
Audit recent database activity and payment records for unauthorized modification.

Patch Information

No official vendor patch is referenced in the published advisories. Maintainers of forks or deployments should refactor manage_payment.php to use prepared statements with bound parameters. Review the VulDB Vulnerability #367531 entry and the upstream IT Source Code Homepage for any updated builds.

Workarounds

Replace direct query concatenation in manage_payment.php with parameterized queries using PDO or mysqli prepared statements.
Enforce strict type validation on the ID parameter, accepting only numeric values before passing to the database layer.
Apply least-privilege database accounts so the application user cannot read or modify tables outside its scope.
Disable verbose SQL error messages in production responses to limit information leakage during probing.

bash

# Example WAF rule (ModSecurity) blocking SQLi in the ID parameter
SecRule REQUEST_URI "@beginsWith /manage_payment.php" \
  "chain,deny,status:403,id:1010253,msg:'CVE-2026-10253 SQLi attempt'"
  SecRule ARGS:ID "@rx (?i)(union|select|sleep\(|--|';|/\*)" "t:none"
