2) SQL injection (CVE-ID: CVE-2023-28329)

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data within the profile field availability condition. A remote user can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

3) Information disclosure (CVE-ID: CVE-2023-28330)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to insufficient sanitizing in backup. A remote user can gain unauthorized access to sensitive information on the system.


4) Cross-site scripting (CVE-ID: CVE-2023-28331)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when outputting database activity filter data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
