Short explanation
In Dokku versions, a user with app-level Dokku access and remote SSH access to execute docker-options commands can store arbitrary strings. These strings are processed by Bash eval, allowing arbitrary command execution on the host.
This critical vulnerability allows attackers to execute arbitrary commands on the host with the privileges of the dokku operating-system user, threatening system confidentiality, integrity, and availability.
What should be done?
- Update Dokku to version 0.38.25 or later
- Follow official vendor advisories
- Audit app-level SSH and docker-options access permissions
Chain of evidence and sources
0.38.25 öncesi Dokku sürümlerinde, docker-options eklentisi aracılığıyla saklanan rastgele dizeler Bash eval tarafından işlenir.
Saklanan değerlerdeki kabuk komutu ikameleri konakta yorumlanarak dokku işletim sistemi kullanıcısının ayrıcalıklarıyla komut yürütülmesini sağlar.
Show the technical text from the sources
Dokku is a docker-powered platform as a service. In Dokku versions before 0.38.25, a user with app-level Dokku access and remote SSH access to execute docker-options commands can store arbitrary strings through the docker-options plugin, and those strings are later concatenated into DOCKER_ARGS and processed by Bash eval during build, deploy, or run operations. Shell command substitutions in the stored values are interpreted on the host, allowing arbitrary command execution with the privileges of the dokku operating-system user. This issue is fixed in version 0.38.25.
