Vulnerability Information

Severity: High
Vulnerability Published: 2019-08-23
Patch Published: 2019-08-08
CVE [?]: CVE-2019-15752
CPE [?]: cpe:/a:docker:docker

Synopsis

The remote host has an application installed that is affected by a privilege escalation vulnerability.

Description

The version of Docker Desktop for Windows is prior to 2.1.0.1. Docker Desktop Community Edition before 2.1.0.1 allows local users to gain privileges by placing a Trojan horse docker-credential-wincred.exe file in %PROGRAMDATA%\DockerDesktop\version-bin\ as a low-privilege user, and then waiting for an admin or service user to authenticate with Docker, restart Docker, or run 'docker login' to force the command.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Docker Desktop version 2.1.0.1 or later

Public Exploits

Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the Docker Desktop < 2.1.0.1 Privilege Escalation vulnerability:

  1. Metasploit: exploit/windows/local/docker_credential_wincred
    [Docker-Credential-Wincred.exe Privilege Escalation]
  2. Exploit-DB: exploits/windows/local/48388.rb
    [EDB-48388: Docker-Credential-Wincred.exe - Privilege Escalation (Metasploit)]

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.

WARNING: Beware of using unverified exploits from sources such as GitHub or Exploit-DB. These exploits and PoCs could contain malware. For more information, see how to use exploits safely.
