osirium Posted August 11, 2017 Report Posted August 11, 2017 Arbitrary code execution via crafted ssh:// in Git """ A malicious third-party can give a crafted "ssh://..." URL to an unsuspecting victim and an attempt to visit the URL can result in any program that exists on the victim's machine being executed. Such a URL could be placed in the .gitmodules file of a malicious project, and an unsuspecting victim could be tricked into running "git clone --recurse-submodules" to trigger the vulnerability.
