Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-6903 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- limited-shell (PyPI): affected all versions up to 0.9.16; no fix listed\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-2016-6903/ (Markdown: https://insights.sbomify.com/CVE-2016-6903/index.md)","id":"CVE-2016-6903","markdown":"https://insights.sbomify.com/CVE-2016-6903/index.md","name":"CVE-2016-6903","record":{"aliases":["GHSA-vw92-qfr4-w98m","PYSEC-2017-154","UBUNTU-CVE-2016-6903"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"lshell restricted shell","requires_auth":"low_privilege","summary":"Authenticated users can escape the restricted lshell environment to execute arbitrary commands, compromising system security.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"debian","cpe":[{"product":"lshell","vendor":"lshell_project"}],"cvss":{"score":9.9,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"lshell 0.9.16 allows remote authenticated users to break out of a limited shell and execute arbitrary commands.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Security feature bypass in n/a","id":"CVE-2016-6903","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"security_feature_bypass","year":"2016"},"n_packages":1,"n_references":7,"next":{"headline":"Information disclosure in VASA Provider for Clustered Data ONTAP","id":"CVE-2016-6904"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.9.16"],"package":"limited-shell","purl":"pkg:pypi/limited-shell","source":"PYSEC-2017-154"}],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2016-6902"},"products":["n/a"],"published":"2017-04-24","related":[{"cvss_score":9.9,"headline":"Security feature bypass in n/a","id":"CVE-2016-6902","kev_date_added":null,"published":"2017-04-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Authenticated users can escape the restricted lshell environment to execute arbitrary commands, compromising system security.","url":"https://insights.sbomify.com/CVE-2016-6903/"}
