Summary
ScanCode.io command injection in docker image fetch process
Details
Command Injection in docker fetch process
Summary
A possible command injection in the docker fetch process as it allows to append malicious commands in the docker_reference parameter.
Details
In the function scanpipe/pipes/fetch.py:fetch_docker_image[1] the parameter docker_reference is user controllable. The docker_reference variable is then passed to the vulnerable function get_docker_image_platform.
def fetch_docker_image(docker_reference, to=None):
"""
code snipped ....
"""
platform_args = []
platform = get_docker_image_platform(docker_reference) # User controlled `docker_reference` passed
"""
code snipped...
"""
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.
def get_docker_image_platform(docker_reference):
"""
Return a platform mapping of a docker reference.
If there are more than one, return the first one by default.
"""
skopeo_executable = _get_skopeo_location()
"""
Constructing a shell command with user controlled variable `docker_reference`
"""
cmd = (
f"{skopeo_executable} inspect --insecure-policy --raw --no-creds "
f"{docker_reference}"
)
logger.info(f"Fetching image os/arch data: {cmd}")
exitcode, output = pipes.run_command(cmd) # Executing command
logger.info(output)
if exitcode != 0:
raise FetchDockerImageError(output)
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.

Mitigations
The docker_reference input should be sanitized to avoid command injections and it is not recommend to create commands with user controlled input directly.

Title
ScanCode.io command injection in docker image fetch process
Summary
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.

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.

Mitigations
The docker_reference input should be sanitized to avoid command injections and it is not recommend to create commands with user controlled input directly.

"details": "## Command Injection in docker fetch process\n\n### Summary\nA possible command injection in the docker fetch process as it allows to append malicious commands in the docker_reference parameter.\n\n\n### Details\nIn the function `scanpipe/pipes/fetch.py:fetch_docker_image`[1] the parameter `docker_reference` is user controllable. The `docker_reference` variable is then passed to the vulnerable function `get_docker_image_platform`. \n```python\ndef fetch_docker_image(docker_reference, to=None):\n \"\"\"\n code snipped ....\n \"\"\"\n platform_args = []\n platform = get_docker_image_platform(docker_reference) # User controlled `docker_reference` passed\n \"\"\"\n code snipped...\n \"\"\"\n```\n\nHowever, 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. \n\n```python\ndef get_docker_image_platform(docker_reference):\n \"\"\"\n Return a platform mapping of a docker reference.\n If there are more than one, return the first one by default.\n \"\"\"\n skopeo_executable = _get_skopeo_location()\n \"\"\"\n Constructing a shell command with user controlled variable `docker_reference`\n \"\"\"\n cmd = (\n f\"{skopeo_executable} inspect --insecure-policy --raw --no-creds \"\n f\"{docker_reference}\"\n )\n\n logger.info(f\"Fetching image os/arch data: {cmd}\")\n exitcode, output = pipes.run_command(cmd) # Executing command\n logger.info(output)\n if exitcode != 0:\n raise FetchDockerImageError(output)\n``` \n\nA malicious user who is able to create or add inputs to a project can inject commands.
