Detailsinfo

A vulnerability was found in Serverless-Devs up to 3.1.11. It has been classified as critical. This affects the function child_process.spawn of the component Init Command. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The "s init" command in Serverless-Devs @serverless-devs/s <= 3.1.11 passes unsanitized user input to child_process.spawn() with shell: true. A URL ending in ".git" bypasses the only input check, allowing OS command injection when a user runs "s init" with an attacker-controlled argument.
