CVE-2022-30636 – Limited directory traversal vulnerability on Windows in golang.org/x/crypto
https://notcve.org/view.php?id=CVE-2022-30636
httpTokenCacheKey uses path.Base to extract the expected HTTP-01 token value to lookup in the DirCache implementation. On Windows, path.Base acts differently to filepath.Base, since Windows uses a different path separator (\ vs. /), allowing a user to provide a relative path, i.e. .well-known/acme-challenge/..\..\asd becomes ..\..\asd. The extracted path is then suffixed with +http-01, joined with the cache directory, and opened. • https://go.dev/cl/408694 https://go.dev/issue/53082 https://pkg.go.dev/vuln/GO-2024-2961 •
