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-2011-3923 exists.\n\nAffected packages and fixed versions:\n- org.apache.struts:struts2-core (Maven): affected from 2.0.0; fixed in 2.3.1.2\n- org.apache.struts:struts2-core (Maven): affected from 2.0.0; fixed in 2.3.1.2\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-2011-3923/ (Markdown: https://insights.sbomify.com/CVE-2011-3923/index.md)","id":"CVE-2011-3923","markdown":"https://insights.sbomify.com/CVE-2011-3923/index.md","name":"CVE-2011-3923","record":{"aliases":["GHSA-j68f-8h6p-9h5q"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web framework","requires_auth":"none","summary":"Remote attackers can bypass security protections in Apache Struts to execute arbitrary commands on the server.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"struts","vendor":"apache"},{"product":"jboss_enterprise_web_server","vendor":"redhat"}],"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-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"Apache Struts before 2.3.1.2 allows remote attackers to bypass security protections in the ParameterInterceptor class and execute arbitrary commands.","ecosystems":["Maven"],"exploits":{"exploitdb":1,"first_seen":"2011-10-01","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2011-10-01","kind":"metasploit","ref":"exploit/multi/http/struts_code_exec_parameters","stars":null,"title":"Apache Struts ParametersInterceptor Remote Code Execution"},{"date":"2013-03-22","kind":"exploitdb","ref":"24874","stars":null,"title":"Apache Struts - 'ParametersInterceptor' Remote Code Execution (Metasploit)"}],"tier":"weaponised"},"has_fix":true,"headline":"Struts ParameterInterceptor vulnerability allows remote command execution","id":"CVE-2011-3923","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:struts","products":["apache:struts"],"type":"command_injection","year":"2011"},"n_packages":2,"n_references":7,"next":{"headline":"Use after free in n/a","id":"CVE-2011-3924"},"packages":[{"ecosystem":"Maven","fixed":["2.3.1.2"],"introduced":["2.0.0"],"last_affected":[],"package":"org.apache.struts:struts2-core","purl":null,"source":"GHSA-j68f-8h6p-9h5q"},{"ecosystem":"Maven","fixed":["2.3.1.2"],"introduced":["2.0.0"],"last_affected":[],"package":"org.apache.struts:struts2-core","purl":"pkg:maven/org.apache.struts/struts2-core","source":"GHSA-j68f-8h6p-9h5q"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-3922"},"products":["Struts"],"published":"2019-11-01","related":[{"cvss_score":9.8,"headline":"Apache Struts Remote Code Execution","id":"CVE-2020-17530","kev_date_added":"2021-11-03","published":"2020-12-11"},{"cvss_score":9.8,"headline":"Apache Struts 1 Improper Input Validation","id":"CVE-2017-9791","kev_date_added":"2022-02-10","published":"2017-07-10"},{"cvss_score":9.8,"headline":"Apache Struts Remote Code Execution","id":"CVE-2017-5638","kev_date_added":"2021-11-03","published":"2017-03-11"},{"cvss_score":9.8,"headline":"Apache Struts 2 Improper Input Validation","id":"CVE-2012-0391","kev_date_added":"2022-01-21","published":"2012-01-08"},{"cvss_score":8.1,"headline":"Apache Struts Remote Code Execution","id":"CVE-2018-11776","kev_date_added":"2021-11-03","published":"2018-08-22"},{"cvss_score":8.1,"headline":"Apache Struts Deserialization of Untrusted Data","id":"CVE-2017-9805","kev_date_added":"2021-11-03","published":"2017-09-15"},{"cvss_score":8.1,"headline":"Apache Struts Command Injection","id":"CVE-2016-3081","kev_date_added":"2026-10-08","published":"2016-04-26"}],"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":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["Apache"]},"summary":"Remote attackers can bypass security protections in Apache Struts to execute arbitrary commands on the server.","url":"https://insights.sbomify.com/CVE-2011-3923/"}
