Bitrix24 is a popular customer relationship management (CRM) tool used by many businesses. Unfortunately, a vulnerability was recently discovered that could allow hackers to launch cross-site scripting (XSS) attacks against Bitrix24 users.

XSS attacks work by tricking users into clicking on a malicious link or submitting data that contains malicious JavaScript code. This code is then executed by the user’s browser when they visit a vulnerable website, allowing the attacker to access data or account credentials.

The specific issue found in Bitrix24 version 22.0.300 relates to how it sanitizes user input for potential XSS payloads. By placing HTML tags at the beginning of a payload, attackers could bypass the sanitization checks and have their JavaScript code executed by others visiting pages on a compromised Bitrix24 account.

If you are a Bitrix24 user, you should make sure to update your installation to the latest version right away to protect yourself from this vulnerability. You should also be cautious of any links or requests asking you to input data into your Bitrix24 account for now. Following basic security practices like using strong and unique passwords can also help reduce your risk.

With XSS attacks on the rise, it’s important for CRM tools and their users to remain vigilant. By updating and practicing safe browsing habits, you can help defend your valuable Bitrix24 account from this and other cyber threats.
