CVE-2022-1838 in Home Clean Services Management System
Summary
by MITRE • 05/24/2022
A vulnerability classified as critical has been found in Home Clean Services Management System 1.0. This affects an unknown part of admin/login.php. The manipulation of the argument username with the input admin%'/**/AND/**/(SELECT/**/5383/**/FROM/**/(SELECT(SLEEP(5)))JPeh)/**/AND/**/'frfq%'='frfq leads to sql injection. It is possible to initiate the attack remotely but it requires authentication. Exploit details have been disclosed to the public.

This vulnerability represents a critical sql injection flaw in the Home Clean Services Management System version 1.0 affecting the admin/login.php component. The vulnerability stems from insufficient input validation and sanitization of the username parameter, allowing malicious actors to inject arbitrary sql code through crafted payloads. The specific exploitation technique leverages time-based sql injection methodology where the attacker crafts a payload containing sleep functions to determine if the injection was successful. The payload admin%'/*/AND//(SELECT//5383//FROM//(SELECT(SLEEP(5)))JPeh)//AND/*/'frfq%'='frfq demonstrates the use of comment syntax and sleep functions to create a timing delay that confirms the vulnerability exists. This approach falls under the category of blind sql injection attacks where traditional error-based methods are not effective. The vulnerability requires authentication to exploit, meaning an attacker must first obtain valid credentials before attempting the sql injection attack. This authentication requirement provides some defense in depth but does not eliminate the critical risk as compromised credentials can lead to complete system compromise. The attack vector operates remotely, allowing attackers to execute sql injection attacks from external networks without physical access to the system. This vulnerability directly maps to CWE-89 which defines sql injection as the insertion of malicious sql code into input fields for execution by the database. The attack technique aligns with ATT&CK tactics including T1190 for exploitation of remote services and T1071.004 for application layer protocol usage. The time-based blind sql injection method used in this exploit is particularly dangerous as it allows attackers to extract data through timing variations without direct output mechanisms. The system's failure to properly sanitize user input during authentication processing creates a pathway for attackers to manipulate the underlying database queries. This vulnerability affects the authentication mechanism specifically, potentially allowing attackers to bypass authentication, extract sensitive user data, or even escalate privileges within the system. The presence of this vulnerability in an administrative login component significantly increases the attack surface and potential impact. Organizations using this system face substantial risk of unauthorized access, data breaches, and potential complete system compromise. The disclosed exploit details accelerate the likelihood of successful attacks and make this vulnerability particularly dangerous for unpatched systems. Security practitioners should prioritize immediate remediation through proper input validation, parameterized queries, and authentication hardening measures to protect against this critical vulnerability. The combination of remote exploitability and the ability to perform time-based data extraction makes this vulnerability particularly concerning for any organization relying on this management system for their operations.
