A user with the ability to create an account could potentially exploit this issue by injecting malicious JavaScript code into another website. XSS vulnerabilities are commonly exploited during phishing attacks, and in the case of OpenCATS, the affected component is exposed directly to users. This issue was discovered by the Insecure.Org research team. Posted on October 9, 2018, the bug notice for OpenCATS v0.9.6 read: In OpenCATS we use a callback component to process a request asynchronously. Callback components are not checked for Cross-site scripting vulnerabilities. This allows an attacker to inject malicious code that can steal sensitive data or even redirect the victim to another page. We advise all users to upgrade to the latest version of OpenCATS as soon as possible.
Safety First: Use Two-Factor Authentication
Two-Factor Authentication (2FA) is an important security precaution that prevents unauthorized access to user accounts. While 2FA is not a 100% guarantee, it can help prevent attackers from accessing your personal information. It's also worth noting that while not every company offers 2FA or will offer it soon, it's still a good idea to set up 2FA on all of your online accounts such as email, social media, and banking. In addition to 2FA being a security measure, there are many other benefits associated with the technology. Users are able to use their mobile device as the second factor in this process, which means users don't have to remember more passwords for sensitive accounts. This technology also increases account security by ensuring only the correct people are gaining access to these accounts.
What is the OpenCATS XSS Bug?
The OpenCATS XSS bug is a vulnerability discovered by the Insecure.Org research team that lets an attacker inject malicious code into a website and steal sensitive data or even redirect the victim to another page. The affected component of this issue is the callback component, which is not checked for Cross-site scripting vulnerabilities. The researchers theorized that this may be due to a lack of experience with callback components and recommended that all users upgrade to the latest version of OpenCATS as soon as possible.
Mitigation Strategy
OpenCATS is an open source web monitoring tool that allows you to easily monitor and compare the security of web applications. In order to protect the OpenCATS user community from potential XSS vulnerabilities, the vulnerability was promptly addressed within hours by updating the vulnerable component.
