Detailsinfo

A vulnerability was found in Dokku up to 0.38.1 and classified as problematic. This issue affects an unknown code block. The manipulation with an unknown input leads to a insufficiently protected credentials vulnerability. Using CWE to declare the problem leads to CWE-522. The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. Impacted is confidentiality. The summary by CVE is:

Dokku is a docker-powered PaaS. Prior to 0.38.2, the git:auth command creates $DOKKU_ROOT/.netrc using bash's touch command, which applies the default umask of 0644. This pre-creation defeats the netrc binary's built-in 0600 permission setting, leaving git credentials readable by any local user who can traverse the dokku home directory. This vulnerability is fixed in 0.38.2.
