An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-12422 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.shiro:shiro-core (Maven): affected all versions; fixed in 1.4.2\n- org.apache.shiro:shiro-core (Maven): affected all versions; fixed in 1.4.2\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-2019-12422/ (Markdown: https://insights.sbomify.com/CVE-2019-12422/index.md)","id":"CVE-2019-12422","markdown":"https://insights.sbomify.com/CVE-2019-12422/index.md","name":"CVE-2019-12422","record":{"aliases":["DEBIAN-CVE-2019-12422","GHSA-r679-m633-g7wc","UBUNTU-CVE-2019-12422"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Java security library","requires_auth":"none","summary":"An attacker can exploit a padding attack on default remember-me cookies to bypass authentication in Apache Shiro.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"shiro","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[],"description":"Apache Shiro before 1.4.2, when using the default \"remember me\" configuration, cookies could be susceptible to a padding attack.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2024-11-08","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2024-11-08T12:30:13Z","kind":"github_poc","ref":"https://github.com/BaiHLiu/RuoYI-4.2-Shiro-721-Docker-PoC","stars":1,"title":"若依4.2 (Shiro 1.4.1) Shiro-721 (CVE-2019-12422)漏洞复现环境"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Improper input validation in Apache Shiro","id":"CVE-2019-12422","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"weak_cryptography","year":"2019"},"n_packages":2,"n_references":2,"next":{"headline":"Private key leak in Apache CXF","id":"CVE-2019-12423"},"packages":[{"ecosystem":"Maven","fixed":["1.4.2"],"introduced":["0"],"last_affected":[],"package":"org.apache.shiro:shiro-core","purl":null,"source":"GHSA-r679-m633-g7wc"},{"ecosystem":"Maven","fixed":["1.4.2"],"introduced":["0"],"last_affected":[],"package":"org.apache.shiro:shiro-core","purl":"pkg:maven/org.apache.shiro/shiro-core","source":"GHSA-r679-m633-g7wc"}],"prev":{"headline":"Apache NiFi user log out issue","id":"CVE-2019-12421"},"products":["Shiro"],"published":"2019-11-18","related":[{"cvss_score":9.8,"headline":"Path Traversal in Apache Shiro","id":"CVE-2023-34478","kev_date_added":null,"published":"2023-07-24"},{"cvss_score":9.8,"headline":"Authentication Bypass Vulnerability in Shiro when forwarding or including via RequestDispatcher","id":"CVE-2022-40664","kev_date_added":null,"published":"2022-10-12"},{"cvss_score":9.8,"headline":"Authentication Bypass Vulnerability","id":"CVE-2022-32532","kev_date_added":null,"published":"2022-06-28"},{"cvss_score":9.8,"headline":"Apache Shiro vulnerable to a specially crafted HTTP request causing an authentication bypass","id":"CVE-2021-41303","kev_date_added":null,"published":"2021-09-17"},{"cvss_score":9.8,"headline":"Authentication bypass in Apache Shiro","id":"CVE-2020-17523","kev_date_added":null,"published":"2021-02-03"},{"cvss_score":9.8,"headline":"Authentication bypass in Apache Shiro","id":"CVE-2020-17510","kev_date_added":null,"published":"2020-11-05"},{"cvss_score":9.8,"headline":"Improper Authentication in Apache Shiro","id":"CVE-2020-11989","kev_date_added":null,"published":"2020-06-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Apache"]},"summary":"An attacker can exploit a padding attack on default remember-me cookies to bypass authentication in Apache Shiro.","url":"https://insights.sbomify.com/CVE-2019-12422/"}
