Synopsis
While researching Oracle WebLogic Docker containers, Tenable discovered a couple of mechanisms to recover the administrative password.
First, the container stores, in cleartext, the administrator's password in a script within the running container. That means anyone with access to the container can uncover the administrative password simply by executing cat create-wls-domain.py and locating the line that starts with admin_pass = . The following screenshot is an example:
Second, the administrator's password also finds its way into the container log. Anyone with access to the logs can simply run the following command to extract the password: docker logs [container id] | grep password.
Tenable notes that Oracle assigned a CVSSv3 score of 7.5 with a vector of AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. However, this score seems off to us. Specifically, local access to the target is required. It's possible that Oracle found an additional and more severe vector, but they didn't inform Tenable as to what that vector is.
