Detailsinfo

A vulnerability was found in Dokku up to 0.38.1. It has been declared as problematic. Affected by this vulnerability is an unknown function. The manipulation with an unknown input leads to a eval injection vulnerability. The CWE definition for the vulnerability is CWE-95. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval"). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Dokku is a docker-powered PaaS. Prior to 0.38.2, the openresty-vhosts plugin copies files from an app's openresty/http-includes/ git repository directory to the host and then interpolates their filenames, unescaped, into a single-quoted shell string that is later parsed by eval. A filename containing a single quote breaks the quoting and allows command substitution to execute arbitrary commands on the host as the dokku user during the app's next deploy. This vulnerability is fixed in 0.38.2.
