CVE-2022-1839 in Home Clean Services Management System
Summary
by MITRE • 05/24/2022
A vulnerability classified as critical was found in Home Clean Services Management System 1.0. This vulnerability affects the file login.php. The manipulation of the argument email with the input admin%'/**/AND/**/(SELECT/**/5383/**/FROM/**/(SELECT(SLEEP(2)))JPeh)/**/AND/**/'frfq%'='frfq leads to sql injection. The attack can be initiated remotely but it requires authentication. Exploit details have been disclosed to the public.

This critical vulnerability exists within the Home Clean Services Management System version 1.0 and represents a classic sql injection flaw in the login.php file. The vulnerability specifically targets the email parameter handling where malicious input can be crafted to manipulate database queries. The attack vector involves a carefully constructed payload that leverages the admin'/*/AND//(SELECT//5383//FROM//(SELECT(SLEEP(2)))JPeh)//AND/*/'frfq'='frfq pattern, which demonstrates a time-based sql injection technique designed to exploit the application's failure to properly sanitize user inputs. This particular implementation utilizes comment syntax and sleep functions to create a timing attack that can reveal database structure information and potentially allow full database access.
The technical exploitation requires an attacker to first authenticate to the system, meaning this vulnerability operates under a privilege escalation model rather than a completely open attack surface. The authentication requirement provides some defense-in-depth but does not eliminate the critical risk since legitimate users with valid credentials could be compromised, or attackers could potentially obtain valid credentials through other means. The vulnerability's classification as critical stems from its potential for data exfiltration, unauthorized access to sensitive information, and possible system compromise. The time-based injection technique used here is particularly dangerous as it can bypass some traditional sql injection detection mechanisms and allows for systematic database enumeration through timing variations.
From an operational impact perspective, this vulnerability creates significant risk for organizations using this specific management system. Successful exploitation could result in unauthorized access to customer data, service records, employee information, and potentially financial data stored within the system. The vulnerability affects the authentication mechanism itself, which means attackers could potentially escalate privileges or gain access to administrative functions. According to cwe standards, this represents a cwe-89 sql injection vulnerability with specific characteristics of time-based blind injection techniques. The attack requires minimal sophistication to execute and can be automated, making it particularly dangerous for organizations that do not maintain current security patches or monitoring systems.
Organizations should implement immediate mitigations including input validation and sanitization for all user-supplied data, particularly in authentication components. The system should be updated with proper sql injection prevention measures such as parameterized queries or prepared statements to eliminate the vulnerability at its source. Network monitoring should be enhanced to detect anomalous timing patterns that may indicate active exploitation attempts. Regular security assessments should be conducted to identify similar vulnerabilities in other system components. Based on attack pattern classifications, this vulnerability aligns with techniques described in the mitre attack framework under initial access and credential access phases. The public disclosure of exploit details significantly increases the risk for unpatched systems, making immediate remediation essential. System administrators should also implement web application firewalls and input validation rules to prevent similar attacks against other vulnerable components within the application ecosystem.
