CVE-2022-48012 Scanner

OpenCATS is an open-source Applicant Tracking System (ATS) used by businesses and recruitment agencies to manage job applications, candidates, and recruitment processes. It is designed to streamline the hiring workflow, allowing users to post job openings, receive applications, manage candidate information, and track the progress of each recruitment phase. As a web-based platform, OpenCATS enables multiple users to access the system simultaneously, facilitating collaborative hiring efforts. Its customization options and integrations with various job boards and social media platforms make it a versatile tool for recruiters. However, like any software, it can be vulnerable to cybersecurity threats, which necessitate regular updates and security checks.

The Cross-Site Scripting (XSS) vulnerability in OpenCATS version 0.9.7 arises from insufficient input validation in the application's settings component. This flaw enables attackers to inject and execute arbitrary JavaScript code in the context of a victim's browser session. Such vulnerabilities are exploited by crafting malicious scripts that are executed when a user interacts with the compromised part of the application, leading to potential security breaches. XSS attacks can lead to session hijacking, personal data theft, and manipulation of displayed content to the end-user.

Specifically, the vulnerability is located in the /opencats/index.php?m=settings&a=ajax_tags_upd component of OpenCATS 0.9.7. It allows attackers to inject malicious script via the tag_title parameter, which lacks proper sanitization and escape mechanisms. When a victim's browser processes this script, it executes within the context of their session, bypassing the same-origin policy. This exploitation vector is particularly concerning because it can be used to steal session cookies or redirect users to phishing sites, highlighting the critical need for input validation and output encoding in web applications.

Exploiting the Cross-Site Scripting vulnerability in OpenCATS could lead to various adverse effects, including but not limited to, the theft of authentication cookies, session hijacking, and the display of fraudulent content. Attackers could potentially gain unauthorized access to sensitive information, manipulate or deface the web application, and launch further attacks against users of the system. The integrity and confidentiality of the data managed by OpenCATS, along with the trust in the platform, can be significantly compromised by such security breaches.
