- Issue
- Issue Summary Due to a flaw in pipenv's parsing of requirements files, an attacker can insert a specially crafted string inside a comment anywhere within a requirements.txt file, which will cause victims who use pipenv to install the requirements file (e.g. with "pipenv install -r requirements.txt") to download dependencies from a package index server controlled by the attacker. By embedding malicious code in packages served from their malicious index server, the attacker can trigger arbitrary remote code execution (RCE) on the victims' systems. Impact The impact of successful exploitation is severe/critical. If an attacker is able to hide a malicious --index-url option in a requirements file that a victim installs with pipenv, the attacker can embed arbitrary malicious code in packages served from their malicious index server that will be executed on the victim's host during installation (remote code execution/RCE). Exploitation using this technique would be relatively simple to…
Recommended action: Upgrade to 2022.1.8 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
