CVE-2023-45285 : What You Need to Know
CVE-2023-45285 poses a risk with 'go get' command falling back to insecure git protocol when fetching a module. Learn about impacts, affected systems, and mitigation steps.
Understanding CVE-2023-45285
This vulnerability involves the command 'go get' potentially reverting to an insecure git protocol when fetching a module, posing risks to users not utilizing the module proxy.
What is CVE-2023-45285?
CVE-2023-45285 outlines a scenario where using 'go get' to obtain a module with the ".git" suffix could lead to fallback to the vulnerable "git://" protocol under certain conditions.
The Impact of CVE-2023-45285
This vulnerability impacts users who directly fetch modules, bypassing the module proxy, and are not utilizing secure protocols like "https://" and "git+ssh://".
