privId SQL Injection Scanner

The software tested for vulnerabilities is privId, which is often used by organizations to manage user identities and access permissions across various applications and services. It aids IT departments and security personnel by simplifying the monitoring and control of user access and privileges. Businesses utilize privId to ensure that only authorized personnel have access to sensitive data and applications. The software is implemented to streamline user provisioning, improve security compliance, and bolster the identity management infrastructure. By consolidating user profiles and access policies, privId helps reduce administrative burdens and enhance operational efficiency. It is a pivotal component in many organizations' identity and access management (IAM) frameworks.

SQL Injection is a common security vulnerability that occurs when user-supplied input is improperly sanitized and executed within SQL queries. This can allow an attacker to manipulate the query, potentially leading to the disclosure of sensitive information, unauthorized actions, and data corruption. The vulnerability usually stems from insufficient validation and escaping of special characters in user input fields. SQL Injection can expose backend database structures and content to attackers, posing significant risks to data confidentiality, integrity, and availability. The exploitation of such vulnerabilities is prevalent due to legacy systems and applications with insecure coding practices. The severity of SQL Injection attacks underscores the importance of robust input validation and parameterized query usage in software development.

Technical details of the SQL Injection vulnerability in privId include a vulnerable endpoint at /E-mobile/App/System/UserSelect/index.php, where the 'privId' parameter is inadequately validated. An attacker can manipulate this parameter using specially crafted SQL code, allowing the execution of arbitrary SQL commands. The vulnerability is exploited through concatenation of SQL commands, which can lead to the disclosure of database names, table structures, and potentially sensitive data. In this particular instance, the attack vector involves passing '1 UNION ALL SELECT NULL,NULL,NULL,NULL,NULL,NULL,(concat(database()))' as input, which is indicative of an attempt to extract database information. Successfully exploiting this vulnerability requires the attacker to possess a basic understanding of SQL syntax and database operations.

Exploiting this vulnerability could have several impacts on the affected system. Attackers could gain unauthorized access to sensitive information stored within the database, such as user credentials, personal data, or business records. This could lead to data breaches, identity theft, and potential legal repercussions for failing to protect customer data. Additionally, attackers might alter database data, causing data integrity issues or disrupting application functionality. If the application relies on the compromised database for business operations, it could result in downtimes, financial losses, and damage to the organization's reputation. Moreover, attackers could leverage the vulnerability to execute further attacks, such as privilege escalation or injecting malicious scripts, exacerbating the security risk.
