Description

A weakness has been identified in itsourcecode Leave Management System 1.0. Affected by this issue is some unknown functionality of the file /login.php. Executing a manipulation of the argument user_email can lead to sql injection. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks.

  "executiveSummary": "A critical SQL injection vulnerability exists in the itsourcecode Leave Management System version 1.0, specifically within the login.php file.\nThe vulnerability arises from improper sanitization of the user_email input parameter, allowing unauthenticated remote attackers to inject malicious SQL commands into the backend database query.\nSuccessful exploitation permits unauthorized access to the database, potentially leading to information disclosure, authentication bypass, or full compromise of the application's data layer.\nGiven that the exploit is publicly available, the risk to deployments is high, necessitating immediate defensive measures to secure the authentication interface against unauthorized data manipulation and extraction.",
  "technicalDetails": "The vulnerability is classified as a classic SQL injection flaw located within the authentication routine of the login.php file. The application fails to adequately validate or parameterize the user_email argument before passing it to the database management system (DBMS) query processor.\nAttack flow begins when an attacker supplies a crafted payload containing SQL syntax (e.g., single quotes, OR conditions, or UNION statements) via the user_email parameter in the login request. Because the application concatenates this user-supplied input directly into the SQL statement, the database interprets the malicious strings as legitimate commands rather than literal data.\nBy manipulating the query structure, an attacker can bypass authentication mechanisms, for instance by injecting 'OR 1=1' logic, which forces the database to return a successful authentication response regardless of the actual password provided.\nBeyond authentication bypass, the lack of input sanitization permits the execution of arbitrary SQL queries. This allows an attacker to perform unauthorized actions such as enumerating database tables, extracting sensitive user credentials, modifying stored data, or potentially performing administrative operations depending on the database user permissions associated with the web application.\nThe vulnerability is accessible remotely over the network, requiring no prior authentication to trigger the flaw. The exposure is categorized as a high-severity risk due to the simplicity of the attack vector and the availability of public exploits. The exploitation process involves intercepting the login request, inserting the injection payload into the user_email field, and submitting the manipulated request to the server, which then processes the malicious database operation."
