The upload password form requires only basic user input, so it is very easy to craft a valid password hash that an attacker can use to authenticate with the application. The application does not force password change notifications to be sent to any particular email addresses, which means that an attacker can easily generate fake email notifications to trick users into changing their passwords. All of these issues can be exploited by an attacker to obtain access to user accounts and to upload malicious code. This vulnerability can be used by an attacker to obtain access to user accounts, upload malicious code, change the password of any user, or do anything else he or she might want to do.

Summary of The Upload Password vulnerability

This vulnerability is located in the upload form of the application. The upload form provides an easy way for users to share their files with others and is a common entry point for attackers to attempt to gain access to user accounts.
The only input required is a password. As such, it's very easy to craft a valid password hash that an attacker can use to authenticate with the application.
The application does not force password change notifications to be sent to any particular email addresses, which means that an attacker can easily generate fake email notifications and trick users into changing their passwords.
All of these issues can be exploited by an attacker to obtain access to user accounts and do anything else he or she might want to do.

Potential Mitigations

Implementing the following mitigations would help to prevent this vulnerability:
- Allowing users to change their passwords via a different method than the form.
- Setting password expiration policy.
- Requiring confirmation of password changes or password resets.
- Adding a CAPTCHA to the upload form.

How to detect if your web application is vulnerable?

To detect if your web application is vulnerable to CVE-2022-37109, you need to patch the vulnerability.
If your web application is vulnerable to this vulnerability, then it should be patched immediately. If you have not yet patched this vulnerability, but still believe that your web application is not vulnerable (e.g., because you have already applied a fix or done some other analysis), please submit a report describing the analysis so that it can be added to the report.
