Tl;dr:
std::process::Commandis vulnerable to shell injection if you invokecmd.exeor*.{cmd,bat}on Windows.Were there actually any real-world use-cases affected by this? Do any of them not deserve to be named and shamed irregardless of this vulnerability?
If it was up to me, I would nuke the cmd custom implementation, leave some helpful compile error messages behind, and direct users to some 3rd party crates to choose from.
Doing such a regression on a Tier 1 target would be a really big blow to the language’s reputation imo
What custom implementation? The escaping logic?
Edit: to be clear, there is no “custom implementation” of
cmditself, nor is the problem exclusive to Rust. This is a problem with the Windowscmditself.
