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-2025-52520 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.0-M1; fixed in 10.1.43\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.0-M1; fixed in 10.1.43\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.9\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.9\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.5.0 up to 8.5.100; no fix listed\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.5.0 up to 8.5.100; no fix listed\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0.M1; fixed in 9.0.107\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 9.0.0.M1; fixed in 9.0.107\n- tomcat (Bitnami): affected all versions; fixed in 9.0.107, 10.1.43, 11.0.9\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 10.1.0-M1; fixed in 10.1.43\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 10.1.0-M1; fixed in 10.1.43\n- org.apache.tomcat:tomcat-catalina (Maven): affected from 11.0.0-M1; fixed in 11.0.9\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-2025-52520/ (Markdown: https://insights.sbomify.com/CVE-2025-52520/index.md)","id":"CVE-2025-52520","markdown":"https://insights.sbomify.com/CVE-2025-52520/index.md","name":"CVE-2025-52520","record":{"aliases":["BIT-tomcat-2025-52520","DEBIAN-CVE-2025-52520","GHSA-wr62-c79q-cv37","ROOT-APP-MAVEN-CVE-2025-52520","UBUNTU-CVE-2025-52520"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"none","summary":"An integer overflow in Apache Tomcat allows attackers to bypass size limits and cause denial of service in specific multipart upload configurations.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"For some unlikely configurations of multipart upload, an Integer Overflow vulnerability in Apache Tomcat could lead to a DoS via bypassing of size limits.\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.8, from 10.1.0-M1 through 10.1.42, from 9.0.0.M1 through 9.0.106.\nThe following versions were EOL at the time the CVE was created but are \nknown to be affected: 8.5.0 through 8.5.100.
