CyberRota Analysis
AI-GeneratedThe vulnerability affects the virtualenv tool on Windows, specifically prior to version 21.7.12, where improper handling of prompt text allows an attacker to inject executable commands into the environment activation script. This can lead to arbitrary command execution with the privileges of the user activating the environment. Organizations using virtualenv for Python development should prioritize updating to the patched version to mitigate potential exploitation risks.

Original NVD Description
virtualenv is a tool for creating isolated virtual python environments. Prior to 21.7.12, BatchActivator.quote() returns prompt text unchanged before activate.bat inserts it into a cmd.exe set "VAR=value" statement. An attacker who influences --prompt, VIRTUALENV_PROMPT, or the corresponding configuration value can include a double quote that closes the assignment and leaves following cmd.exe operators as executable syntax. When a user activates the generated Windows environment, the injected commands run with that user's privileges. This issue is fixed in version 21.7.12.
