Nortek Linear eMerge E3-Series is an advanced access control management system used by businesses and commercial entities for securing premises. It is designed to provide comprehensive security solutions, integrating various access points into a cohesive system. The system is often implemented in environments where access needs to be monitored and controlled effectively, such as in corporate buildings, industrial sites, and educational institutions. Its management software is employed by IT and facility managers to streamline the administration of security permissions and monitor activity. The platform is utilized globally, providing scalable security managing applications for premises ranging from small to large-scale. By enabling centralized control, it aims to enhance security protocols and safeguard property and personnel.
SQL Injection is a type of vulnerability allowing attackers to interfere with the queries an application makes to its database. This vulnerability allows attackers to view data that they are not supposed to retrieve, such as other users' data. It can also lead to data modification or deletion, causing persistent changes to content. The injection is executed through malicious SQL code inserted into input fields or request parameters. It is a high-risk vulnerability as it can lead to unauthorized data access and potential data breaches affecting application integrity and confidentiality. SQL Injection attacks are often employed by attackers as a means to bypass access controls and gain undue advantages from compromised systems. Due to its critical nature, effective measures must be taken to detect and mitigate this vulnerability.
The SQL injection vulnerability in the Nortek Linear eMerge E3-Series systems is triggered through the "idt" parameter. It is found across various firmware versions such as 0.32-08f, 0.32-07p, and others. Attackers leverage this vulnerability by manipulating the input to the "idt" parameter in a crafted URL directed at the system. The vulnerability occurs due to inadequate input validation, allowing an attacker to append malicious SQL code. If exploited successfully, this can manipulate SQL queries that interact with the underlying database. This flaw could allow disclosure or modification of data stored by the Nortek access control system. It is a critical vulnerability that attackers can exploit to gain unauthorized access to sensitive information.
When exploited, the SQL Injection vulnerability could enable malicious actors to perform actions such as data theft, unauthorized access, and database tampering. Sensitive information pertaining to building access and system configurations could be exposed. Attackers may modify, delete or even add rogue data, compromising the integrity of security protocols. This could result in unauthorized access to secure areas, jeopardizing the safety of individuals and assets. Additionally, exploitation might lead to complete database exposure, putting the organization at risk of further cyber-attacks. The business could face legal and financial consequences due to compliance violations and loss of stakeholder trust.
