{"cve":"CVE-2023-39523","nvd":{"published":"2023-08-07T21:15:09.553","modified":"2026-06-17T06:12:30.937","status":"Modified","description":"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.\n\nIn 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.\n\nVersion 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-77"],"references":["https://github.com/nexB/scancode.io/blob/main/scanpipe/pipes/fetch.py#L185","https://github.com/nexB/scancode.io/commit/07ec0de1964b14bf085a1c9a27ece2b61ab6105c","https://github.com/nexB/scancode.io/releases/tag/v32.5.1","https://github.com/nexB/scancode.io/security/advisories/GHSA-2ggp-cmvm-f62f","https://github.com/nexB/scancode.io/blob/main/scanpipe/pipes/fetch.py#L185"],"products":["nexb:scancode.io"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-39523","score":0.02922,"percentile":0.87043,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-2ggp-cmvm-f62f","url":"https://osv.dev/vulnerability/GHSA-2ggp-cmvm-f62f","summary":"ScanCode.io command injection in docker image fetch process","modified":"2026-09-10T03:50:08.700430387Z","packages":[{"ecosystem":"PyPI","name":"scancodeio","purl":"pkg:pypi/scancodeio","ranges":["<32.5.1"],"fixed":["32.5.1"]}]},{"id":"PYSEC-2026-1904","url":"https://osv.dev/vulnerability/PYSEC-2026-1904","summary":"ScanCode.io command injection in docker image fetch process","modified":"2026-07-07T17:47:37.712622767Z","packages":[{"ecosystem":"PyPI","name":"scancodeio","purl":"pkg:pypi/scancodeio","ranges":["<32.5.1"],"fixed":["32.5.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
