This critical sql injection vulnerability exists in the keerti1924 PHP-MYSQL-User-Login-System version 1.0, specifically within the /login.php file where the email parameter is improperly handled. The flaw allows remote attackers to execute arbitrary sql commands by manipulating the email argument, potentially leading to complete database compromise and unauthorized access to user credentials. This vulnerability represents a classic sql injection attack vector where user input is directly incorporated into sql queries without proper sanitization or parameterization. The issue is particularly dangerous because it affects the core authentication functionality of the system, making it a prime target for attackers seeking to escalate privileges or extract sensitive user data.
The technical implementation of this vulnerability stems from improper input validation and sanitization practices within the php application code. When the email parameter is submitted through the login form, the application fails to properly escape or parameterize the input before incorporating it into database queries. This creates an environment where malicious actors can inject sql payload sequences that manipulate the intended query execution flow. The vulnerability maps to CWE-89 which specifically addresses improper neutralization of special elements used in sql commands, and aligns with ATT&CK technique T1190 for exploiting vulnerabilities in web applications. The remote exploitability means that attackers do not require physical access to the system and can leverage this weakness from any network location.
The operational impact of this vulnerability is severe and multifaceted, encompassing data theft, unauthorized access, and potential system compromise. Successful exploitation could result in the exposure of all user accounts including usernames, passwords, and potentially sensitive personal information stored in the database. Attackers might also leverage this vulnerability to escalate privileges, modify database contents, or even establish persistence mechanisms within the compromised system. The disclosure of this vulnerability through public channels like VDB-256034 increases the likelihood of automated exploitation attempts, making the system vulnerable to widespread attack. Organizations relying on this login system face significant risk of data breaches, regulatory compliance violations, and reputational damage if the vulnerability remains unpatched.
Mitigation strategies for this vulnerability must be implemented immediately to protect against exploitation. The primary remediation involves implementing proper input validation and parameterized queries throughout the application code, particularly in the login.php file where the vulnerability occurs. All user inputs should be sanitized and validated before being incorporated into database operations, with prepared statements or parameterized queries being the recommended approach to prevent sql injection. Additionally, implementing web application firewalls and input filtering mechanisms can provide additional layers of protection. Organizations should also conduct comprehensive code reviews to identify similar vulnerabilities in other application components and establish secure coding practices. The lack of vendor response to early disclosure highlights the importance of proactive security measures and the need for organizations to maintain independent vulnerability assessment capabilities rather than relying solely on vendor patches.
