The vulnerability CVE-2018-7313 represents a critical sql injection flaw within the CW Tags 2.0.6 component for Joomla based web applications where the cw tags component was installed.
The technical implementation of this vulnerability stems from inadequate input validation and parameter sanitization within the cw tags component. When users submit search queries through the searchtext array parameter, the application fails to properly escape or validate the input before incorporating it into sql queries. This creates a classic sql injection scenario where attackers can manipulate the underlying database queries by injecting malicious sql payloads. The vulnerability manifests when the component processes array-based parameters without proper sanitization, allowing sql commands to be executed with the privileges of the web application's database user. The flaw specifically impacts versions of the cw tags component prior to 2.0.7 and affects joomla! installations where this particular component is deployed.
The operational impact of CVE-2018-7313 extends beyond simple data theft or modification. Attackers can leverage this vulnerability to extract sensitive information from the database including user credentials, personal data, and system configuration details. The vulnerability also enables attackers to modify or delete database records, potentially leading to complete system compromise. Additionally, the attack can be used to escalate privileges within the database, allowing for further exploitation of the underlying system. The vulnerability affects not only the joomla installations face significant risk of data breaches, service disruption, and potential regulatory compliance violations.
Organizations should immediately update their joomla installations and ensure all third-party extensions are kept current with security patches.
