An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-29390 exists.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-29390/ (Markdown: https://insights.sbomify.com/CVE-2020-29390/index.md)","id":"CVE-2020-29390","markdown":"https://insights.sbomify.com/CVE-2020-29390/index.md","name":"CVE-2020-29390","record":{"aliases":["GHSA-wfh6-xhqh-h5xw"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Zeroshell Linux Distribution","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary system commands on Zeroshell via shell metacharacters in the kerbynet CGI parameter.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zeroshell","vendor":"zeroshell"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Zeroshell 3.9.3 contains a command injection vulnerability in the /cgi-bin/kerbynet StartSessionSubmit parameter that could allow an unauthenticated attacker to execute a system command by using shell metacharacters and the %0a character.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2020/CVE-2020-29390.yaml","stars":null,"title":"Zeroshell 3.9.3 - Command Injection"}],"tier":"weaponised"},"has_fix":null,"headline":"Command injection in n/a","id":"CVE-2020-29390","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2020-29392"},"packages":[],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2020-29389"},"products":["n/a"],"published":"2020-11-30","related":[{"cvss_score":10,"headline":"Command injection in n/a","id":"CVE-2009-0545","kev_date_added":null,"published":"2009-02-12"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12725","kev_date_added":null,"published":"2019-07-19"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2021-41738","kev_date_added":null,"published":"2022-06-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Unauthenticated attackers can execute arbitrary system commands on Zeroshell via shell metacharacters in the kerbynet CGI parameter.","url":"https://insights.sbomify.com/CVE-2020-29390/"}
