Deleted dependency detected

[ashishbijlani]

I'm a Cyber Security researcher and developer of PackjGuard [1] to address open-source software supply chain attacks.

Issue

During my research, I found that this repo is vulnerable to attack due to missing deleted dependency from the public PyPI registry.

Details

Specifically, file https://github.com/Jugendhackt/Viren-Simulation/blob/e2ef53ad9d756635fd63818a1d6c4747c6560631/flask/requirements.txt lists crackmapexec as one of the dependencies. However, it has been deleted from public PyPI. As such, an external bad actor can claim that name and register a malicious package, which will be then installed with pip install command, resulting in arbitrary remote code execution.

Impact

Not only your apps/services using https://github.com/Jugendhackt/Viren-Simulation repo code are vulnerable to this attack, but the users of your open-source Github repo could also fall victim.

Remediation

Please manually register a placeholder crackmapexec package on PyPI immediately or remove crackmapexec dependency from https://github.com/Jugendhackt/Viren-Simulation/blob/e2ef53ad9d756635fd63818a1d6c4747c6560631/flask/requirements.txt to fix this vulnerability.

To automatically fix such issues in future, please install PackjGuard Github app [1].

Thanks!
