CVE-2022-30636

Publication date 2 July 2024

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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. Since the controlled path is suffixed with +http-01 before opening, the impact of this is significantly limited, since it only allows reading arbitrary files on the system if and only if they have this suffix.

Notes

mdeslaur

Packages built using golang need to be rebuilt once the vulnerability has been fixed. This CVE entry does not list packages that need rebuilding outside of the main repository or the Ubuntu variants with PPA overlays. Warning: do not include nullboot in the list of no-change rebuilds after fixing an issue in golang.

Only affects golang on Windows so golang on Ubuntu is not affected
