{"id":"CVE-2023-39523","aliases":["GHSA-2ggp-cmvm-f62f","PYSEC-2026-1904"],"url":"https://o3.security/vulnerability/CVE-2023-39523","summary":"ScanCode.io command injection in docker image fetch process","details":"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.","published":"2023-08-07T20:55:46.855Z","modified":"2026-07-15T01:49:18.684682741Z","cvss":{"score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"PyPI","name":"scancodeio","fixedVersion":"32.5.1"}],"fix":{"url":"https://github.com/nexB/scancode.io/commit/07ec0de1964b14bf085a1c9a27ece2b61ab6105c","label":"nexB/scancode.io@07ec0de"},"references":[{"type":"WEB","url":"https://github.com/nexB/scancode.io/blob/main/scanpipe/pipes/fetch.py#L185"},{"type":"WEB","url":"https://github.com/nexB/scancode.io/releases/tag/v32.5.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/39xxx/CVE-2023-39523.json"},{"type":"ADVISORY","url":"https://github.com/nexB/scancode.io/security/advisories/GHSA-2ggp-cmvm-f62f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-39523"},{"type":"FIX","url":"https://github.com/nexB/scancode.io/commit/07ec0de1964b14bf085a1c9a27ece2b61ab6105c"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:18.684682741Z"}}
