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-2011-2526 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tomcat:tomcat (Maven): affected all versions; fixed in 5.5.34\n- org.apache.tomcat:tomcat (Maven): affected all versions; fixed in 5.5.34\n- org.apache.tomcat:tomcat (Maven): affected from 6.0.0; fixed in 6.0.33\n- org.apache.tomcat:tomcat (Maven): affected from 6.0.0; fixed in 6.0.33\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.19\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.19\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-2011-2526/ (Markdown: https://insights.sbomify.com/CVE-2011-2526/index.md)","id":"CVE-2011-2526","markdown":"https://insights.sbomify.com/CVE-2011-2526/index.md","name":"CVE-2011-2526","record":{"aliases":["GHSA-9ggm-7897-x4mg"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Apache Tomcat server","requires_auth":"low_privilege","summary":"Local attackers can bypass file access restrictions or cause denial of service in Apache Tomcat when sendfile is enabled.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":4.4,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.19, when sendfile is enabled for the HTTP APR or HTTP NIO connector, does not validate certain request attributes, which allows local users to bypass intended file access restrictions or cause a denial of service (infinite loop or JVM crash) by leveraging an untrusted web application.","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 Input Validation in Apache Tomcat","id":"CVE-2011-2526","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:tomcat","products":["apache:tomcat"],"type":"security_feature_bypass","year":"2011"},"n_packages":6,"n_references":38,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2011-2527"},"packages":[{"ecosystem":"Maven","fixed":["5.5.34"],"introduced":["0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-9ggm-7897-x4mg"},{"ecosystem":"Maven","fixed":["5.5.34"],"introduced":["0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-9ggm-7897-x4mg"},{"ecosystem":"Maven","fixed":["6.0.33"],"introduced":["6.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-9ggm-7897-x4mg"},{"ecosystem":"Maven","fixed":["6.0.33"],"introduced":["6.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-9ggm-7897-x4mg"},{"ecosystem":"Maven","fixed":["7.0.19"],"introduced":["7.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":null,"source":"GHSA-9ggm-7897-x4mg"},{"ecosystem":"Maven","fixed":["7.0.19"],"introduced":["7.0.0"],"last_affected":[],"package":"org.apache.tomcat:tomcat","purl":"pkg:maven/org.apache.tomcat/tomcat","source":"GHSA-9ggm-7897-x4mg"}],"prev":{"headline":"Null dereference in n/a","id":"CVE-2011-2525"},"products":["n/a"],"published":"2011-07-14","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 -
