Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-0763 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.68\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.68\n- org.apache.tomcat:tomcat (Maven): affected from 8.0.0; fixed in 8.0.32\n- org.apache.tomcat:tomcat (Maven): affected from 8.0.0; fixed in 8.0.32\n- org.apache.tomcat:tomcat (Maven): affected from 9.0.0M1; fixed in 9.0.0.M3\n- org.apache.tomcat:tomcat (Maven): affected from 9.0.0M1; fixed in 9.0.0.M3\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-2016-0763/ (Markdown: https://insights.sbomify.com/CVE-2016-0763/index.md)","id":"CVE-2016-0763","markdown":"https://insights.sbomify.com/CVE-2016-0763/index.md","name":"CVE-2016-0763","record":{"aliases":["GHSA-9hjv-9h75-xmpp","UBUNTU-CVE-2016-0763"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"low_privilege","summary":"Remote authenticated users can bypass SecurityManager restrictions to read or write arbitrary application data or cause denial of service.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"tomcat","vendor":"apache"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":6.3,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"The setGlobalContext method in org/apache/naming/factory/ResourceLinkFactory.java in Apache Tomcat 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M3 does not consider whether ResourceLinkFactory.setGlobalContext callers are authorized, which allows remote authenticated users to bypass intended SecurityManager restrictions and read or write to arbitrary application data, or cause a denial of service (application disruption), via a web application that sets a crafted global context.","ecosystems":["Maven"],"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":"Improper Verification of Source of a Communication Channel in Apache Tomcat","id":"CVE-2016-0763","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:tomcat","products":["apache:tomcat","canonical:ubuntu_linux","debian:debian_linux"],"type":"missing_authorization","year":"2016"},"n_packages":6,"n_references":33,"next":{"headline":"Race condition in n/a","id":"CVE-2016-0764"},"packages":[{"ecosystem":"Maven","fixed":["7.0.68"],"introduced":["7.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-9hjv-9h75-xmpp"},{"ecosystem":"Maven","fixed":["7.0.68"],"introduced":["7.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-9hjv-9h75-xmpp"},{"ecosystem":"Maven","fixed":["8.0.32"],"introduced":["8.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-9hjv-9h75-xmpp"},{"ecosystem":"Maven","fixed":["8.0.32"],"introduced":["8.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-9hjv-9h75-xmpp"},{"ecosystem":"Maven","fixed":["9.0.0.M3"],"introduced":["9.0.0M1"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-9hjv-9h75-xmpp"},{"ecosystem":"Maven","fixed":["9.0.0.M3"],"introduced":["9.0.0M1"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-9hjv-9h75-xmpp"}],"prev":{"headline":"Observable Discrepancy in Apache Tomcat","id":"CVE-2016-0762"},"products":["n/a"],"published":"2016-02-25","related":[{"cvss_score":10,"headline":"Apache Tomcat Path Equivalence","id":"CVE-2025-24813","kev_date_added":"2025-04-01","published":"2025-03-10"},{"cvss_score":9.8,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2016-8735","kev_date_added":"2023-05-12","published":"2017-04-06"},{"cvss_score":8.1,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2017-12617","kev_date_added":"2022-03-25","published":"2017-10-03"},{"cvss_score":8.1,"headline":"Apache Tomcat on Windows Remote Code Execution","id":"CVE-2017-12615","kev_date_added":"2022-03-25","published":"2017-09-19"},{"cvss_score":7.5,"headline":"Apache Tomcat Missing Encryption of Sensitive Data","id":"CVE-2026-34486","kev_date_added":"2026-08-04","published":"2026-04-09"},{"cvss_score":9.8,"headline":"Apache Tomcat: HTTP/2 no-authority bypass of strict SNI validation -
