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-2020-17523 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.shiro:shiro-spring (Maven): affected all versions; fixed in 1.7.1\n- org.apache.shiro:shiro-spring (Maven): affected all versions; fixed in 1.7.1\n- org.apache.shiro:shiro-spring-boot-starter (Maven): affected all versions; fixed in 1.7.1\n- org.apache.shiro:shiro-spring-boot-starter (Maven): affected all versions; fixed in 1.7.1\n- org.apache.shiro:shiro-web (Maven): affected all versions; fixed in 1.7.1\n- org.apache.shiro:shiro-web (Maven): affected all versions; fixed in 1.7.1\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-2020-17523/ (Markdown: https://insights.sbomify.com/CVE-2020-17523/index.md)","id":"CVE-2020-17523","markdown":"https://insights.sbomify.com/CVE-2020-17523/index.md","name":"CVE-2020-17523","record":{"aliases":["GHSA-v98j-7crc-wvrj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Java security library","requires_auth":"none","summary":"Attackers can bypass authentication in Apache Shiro when integrated with Spring via specially crafted HTTP requests.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"shiro","vendor":"apache"}],"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-287","name":"Improper Authentication"}],"description":"Apache Shiro before 1.7.1, when using Apache Shiro with Spring, a specially crafted HTTP request may cause an authentication bypass.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2021-02-03","github_poc":1,"max_poc_stars":118,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-02-03T08:14:03Z","kind":"github_poc","ref":"https://github.com/jweny/shiro-cve-2020-17523","stars":118,"title":"shiro-cve-2020-17523 漏洞的两种绕过姿势分析 以及配套的漏洞环境"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Authentication bypass in Apache Shiro","id":"CVE-2020-17523","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":6,"n_references":8,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-17524"},"packages":[{"ecosystem":"Maven","fixed":["1.7.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.shiro:shiro-spring","purl":null,"source":"GHSA-v98j-7crc-wvrj"},{"ecosystem":"Maven","fixed":["1.7.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.shiro:shiro-spring","purl":"pkg:maven/org.apache.shiro/shiro-spring","source":"GHSA-v98j-7crc-wvrj"},{"ecosystem":"Maven","fixed":["1.7.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.shiro:shiro-spring-boot-starter","purl":null,"source":"GHSA-v98j-7crc-wvrj"},{"ecosystem":"Maven","fixed":["1.7.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.shiro:shiro-spring-boot-starter","purl":"pkg:maven/org.apache.shiro/shiro-spring-boot-starter","source":"GHSA-v98j-7crc-wvrj"},{"ecosystem":"Maven","fixed":["1.7.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.shiro:shiro-web","purl":null,"source":"GHSA-v98j-7crc-wvrj"},{"ecosystem":"Maven","fixed":["1.7.1"],"introduced":["0"],"last_affected":[],"package":"org.apache.shiro:shiro-web","purl":"pkg:maven/org.apache.shiro/shiro-web","source":"GHSA-v98j-7crc-wvrj"}],"prev":{"headline":"Cache Manipulation Attack in Apache Traffic Control","id":"CVE-2020-17522"},"products":["Apache Shiro"],"published":"2021-02-03","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-2020-17510","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"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":["n/a"]},"summary":"Attackers can bypass authentication in Apache Shiro when integrated with Spring via specially crafted HTTP requests.","url":"https://insights.sbomify.com/CVE-2020-17523/"}
