It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-0721 in the wild and no public exploit code.\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-2011-0721/ (Markdown: https://insights.sbomify.com/CVE-2011-0721/index.md)","id":"CVE-2011-0721","markdown":"https://insights.sbomify.com/CVE-2011-0721/index.md","name":"CVE-2011-0721","record":{"aliases":["DEBIAN-CVE-2011-0721","DSA-2164-1","GHSA-6wqp-749m-jfw7"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux shadow utilities","requires_auth":"low_privilege","summary":"Local attackers can inject CRLF characters into GECOS fields to modify /etc/passwd, potentially adding unauthorized users or groups.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"shadow","vendor":"debian"}],"cvss":{"score":6.4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Multiple CRLF injection vulnerabilities in (1) chfn and (2) chsh in shadow 1:4.1.4 allow local users to add new users or groups to /etc/passwd via the GECOS field.","ecosystems":[],"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":"Other in n/a","id":"CVE-2011-0721","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2011"},"n_packages":0,"n_references":11,"next":{"headline":"Memory corruption in n/a","id":"CVE-2011-0722"},"packages":[],"prev":{"headline":"Plone Privilege Escalation Vulnerability","id":"CVE-2011-0720"},"products":["n/a"],"published":"2011-02-18","related":[{"cvss_score":7.2,"headline":"Path traversal in n/a","id":"CVE-2008-5394","kev_date_added":null,"published":"2008-12-09"},{"cvss_score":4.6,"headline":"Security feature bypass in n/a","id":"CVE-2004-1001","kev_date_added":null,"published":"2004-11-04"},{"cvss_score":3.7,"headline":"Misconfiguration in n/a","id":"CVE-2006-1174","kev_date_added":null,"published":"2006-05-28"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Local attackers can inject CRLF characters into GECOS fields to modify /etc/passwd, potentially adding unauthorized users or groups.","url":"https://insights.sbomify.com/CVE-2011-0721/"}
