CVE-2022-0213 vim is vulnerable to Heap-based Buffer Overflow

Poster -

This flaw is present in the ‘indent’ and ‘cindent’ plugins. It was discovered by Soroush Dalirian of VDAC. An attacker can leverage this bug to execute arbitrary code on the system. There is no need to send the victim a malicous email or trick them into visiting a malicious website. An attacker can exploit this flaw by placing a malicous buffer in the code of a blog post, a form, or a staff member’s report. Once the victim saves the malicous buffer, the malicious code is executed.

Heap-based Buffer Overflow in vim is a well-known issue, and there are multiple mitigations available. However, there is no perfect solution to this issue. For example, most editors have an option to disable unsafe paste, but this option is not available in vim. Another option is to use an anti-virus software, and this can be done for every file that is opened. However, anti-virus software cannot detect or prevent every malicous code.

vim Heap-based Buffer Overflow

Vim is an editor that is designed for text editing. It is used by programmers, system administrators, and content editors. Vim is capable of supporting multiple programming languages. Vim has a plugin manager that enables users to install additional plugins. The most popular plugins are the ‘indent’ and ‘cindent’ plugins. This flaw in these two plugins can be exploited by any user with access to the editor on a vulnerable machine. The attacker needs to send a malicous buffer to the victim’s machine. Once it is saved, malicious code is executed on the target machine.

Recommendations:
1) Use anti-virus software on every file that is opened
2) Disable unsafe paste in vim

Vim has a wide variety of commands that can help you learn more and develop more. Server-side programs, such as Vim and MySQL, are often hackers’ target for exploitation. This is because these programs have the opportunity to be used in many different contexts—for instance, when an attacker infects a website with malware or when an attacker creates a malicious email.

The above write up discusses security risks with the ‘indent’ and ‘cindent’ plugins in vim. This write up helps you learn more about vim and it's capabilities.
