iboss Secure Web Gateway Cross-Site Scripting (XSS) Scanner

iboss Secure Web Gateway is widely used by organizations to protect against threats and enforce policies across their network. It functions as a web security platform offering advanced threat protection and data loss prevention. Cybersecurity teams rely on this product to safeguard users while browsing the internet. In addition, administrators can configure custom filtering, reporting, and compliance settings. The product is specifically tailored for enterprise environments needing comprehensive web security solutions. Its usage extends to industries requiring continuous monitoring and control of web traffic.

The Cross-Site Scripting (XSS) vulnerability inherent in the iboss Secure Web Gateway poses significant security challenges. It allows attackers to inject malicious scripts into web pages viewed by other users. The attack is facilitated by improper sanitization of user inputs, specifically affecting the "redirectUrl" parameter. When exploited, attackers can execute arbitrary scripts within the context of the user's session. This vulnerability can compromise the confidentiality, integrity, and availability of user data. It is critical as it allows persistent unauthorized actions on a website without user awareness.

The vulnerability is technically instantiated by manipulating the "redirectUrl" parameter in the login request of iboss Secure Web Gateway. An attacker submits a crafted login attempt, intercepts the request, modifies the parameter, and includes a malicious payload. Subsequently, this payload is executed in the security context of the victim's browser session. The vulnerability primarily affects the application's login endpoint where the attack vector is introduced. Consequently, it is triggered when a user accesses the affected components of the application under unsanitized conditions.

When exploited, this XSS vulnerability can have numerous adverse effects on organizations using iboss Secure Web Gateway. It enables attackers to hijack user sessions and gain unauthorized access to sensitive data. Malicious actors can execute drive-by-download attacks, steal credentials, and implant persistent defacements. Furthermore, it can lead to escalation of privileges, allowing attackers to manipulate administration interfaces. In extreme scenarios, this can degrade system performance and propagate malware across the organizational network. It undermines trust in affected systems and disrupts normal business operations.
