CVE-2023-39523
August 07, 2023
ScanCode.io is a server to script and automate software composition analysis with ScanPipe pipelines. Prior to version 32.5.1, the software has a possible command injection vulnerability in the docker fetch process as it allows to append malicious commands in the "docker_reference" parameter.
In the function "scanpipe/pipes/fetch.py:fetch_docker_image" the parameter "docker_reference" is user controllable. The "docker_reference" variable is then passed to the vulnerable function "get_docker_image_platform". However, the "get_docker_image_plaform" function constructs a shell command with the passed "docker_reference". The "pipes.run_command" then executes the shell command without any prior sanitization, making the function vulnerable to command injections. A malicious user who is able to create or add inputs to a project can inject commands. Although the command injections are blind and the user will not receive direct feedback without logs, it is still possible to cause damage to the server/container. The vulnerability appears for example if a malicious user adds a semicolon after the input of "docker://;", it would allow appending malicious commands.
Version 32.5.1 contains a patch for this issue. The "docker_reference" input should be sanitized to avoid command injections and, as a workaround, one may avoid creating commands with user controlled input directly.
