Improper Control of Generation of Code ('Code Injection')

Affected versions of this package are vulnerable to Improper Control of Generation of Code ('Code Injection') through the package_index module's download functions due to the unsafe usage of os.system. An attacker can execute arbitrary commands on the system by providing malicious URLs or manipulating the URLs retrieved from package index servers.

Note

Because easy_install and package_index are deprecated, the exploitation surface is reduced, but it's conceivable through social engineering or minor compromise to a package index could grant remote access.

How to fix Improper Control of Generation of Code ('Code Injection')?

Upgrade setuptools to version 70.0.0 or higher.

[,70.0.0)
  • M
Regular Expression Denial of Service (ReDoS)

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via crafted HTML package or custom PackageIndex page.

Note:

Only a small portion of the user base is impacted by this flaw. Setuptools maintainers pointed out that package_index is deprecated (not formally, but “in spirit”) and the vulnerability isn't reachable through standard, recommended workflows.

How to fix Regular Expression Denial of Service (ReDoS)?

Upgrade setuptools to version 65.5.1 or higher.
