An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-0221 exists.\n\nAffected packages and fixed versions:\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 7.0.0; fixed in 7.0.94\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 7.0.0; fixed in 7.0.94\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.5.0; fixed in 8.5.40\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.5.0; fixed in 8.5.40\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0; fixed in 9.0.17\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0; fixed in 9.0.17\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.94\n- org.apache.tomcat:tomcat (Maven): affected from 7.0.0; fixed in 7.0.94\n- org.apache.tomcat:tomcat (Maven): affected from 8.5.0; fixed in 8.5.40\n- org.apache.tomcat:tomcat (Maven): affected from 8.5.0; fixed in 8.5.40\n- org.apache.tomcat:tomcat (Maven): affected from 9.0.0; fixed in 9.0.17\n- org.apache.tomcat:tomcat (Maven): affected from 9.0.0; fixed in 9.0.17\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-2019-0221/ (Markdown: https://insights.sbomify.com/CVE-2019-0221/index.md)","id":"CVE-2019-0221","markdown":"https://insights.sbomify.com/CVE-2019-0221/index.md","name":"CVE-2019-0221","record":{"aliases":["CLSA-2022-1670606563","DEBIAN-CVE-2019-0221","DLA-1810-1","GHSA-jjpq-gp5q-8q6w","UBUNTU-CVE-2019-0221"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Cross-site scripting vulnerability in Apache Tomcat SSI printenv command allows attackers to execute arbitrary scripts if SSI is enabled.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The SSI printenv command in Apache Tomcat 9.0.0.M1 to 9.0.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 echoes user provided data without escaping and is, therefore, vulnerable to XSS.
