Assigner: VulnCheck

Description
Nominas 0.27 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the username parameter. Attackers can send POST requests to the login/checklogin.php endpoint with crafted UNION-based SQL injection payloads to extract database information including usernames, database names, and version details.

Executive Summary

[{'type': 'paragraph', 'content': "Nominas version 0.27 contains a SQL injection vulnerability in the 'username' parameter during the login process. This vulnerability exists in the PHP script at /login/checklogin.php, which processes POST requests for user authentication."}, {'type': 'paragraph', 'content': "An attacker can exploit this flaw by injecting malicious SQL code through the 'username' field, using UNION-based SQL injection payloads. This allows the attacker to execute arbitrary SQL queries on the database."}, {'type': 'paragraph', 'content': 'By exploiting this vulnerability, attackers can extract sensitive database information such as usernames, database names, and database version details without needing any authentication.'}] [1, 2]

Impact Analysis

This vulnerability allows unauthenticated attackers to execute arbitrary SQL queries on the Nominas database, potentially leading to unauthorized disclosure of sensitive information.

  • Attackers can retrieve sensitive data such as usernames, database names, and database version details.
  • The exposure of database details can facilitate further attacks against the system.

Because the attack requires no privileges or user interaction and has low attack complexity, it poses a high risk to the confidentiality of the system.

Detection Guidance

[{'type': 'paragraph', 'content': "This vulnerability can be detected by sending crafted POST requests to the login/checklogin.php endpoint with SQL injection payloads in the 'username' parameter and observing the response for database information leakage."}, {'type': 'paragraph', 'content': 'A typical test command using curl might look like this:'}, {'type': 'list_item', 'content': 'curl -X POST -d "username=\' UNION ALL SELECT 0x31,0x32,0x33,CONCAT_WS(0x203a20,USER(),DATABASE(),VERSION())-- " -d "password=anything" http://targetsite/login/checklogin.php'}, {'type': 'paragraph', 'content': 'If the response contains database user, database name, or version information, it indicates the presence of the SQL injection vulnerability.'}] [1, 2]
