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-2009-0580 exists.\n\nAffected packages and fixed versions:\n- org.apache.tomcat:tomcat (Maven): affected from 4.1.0; fixed in 4.1.40\n- org.apache.tomcat:tomcat (Maven): affected from 4.1.0; fixed in 4.1.40\n- org.apache.tomcat:tomcat (Maven): affected from 5.0.0; fixed in 5.5.28\n- org.apache.tomcat:tomcat (Maven): affected from 5.0.0; fixed in 5.5.28\n- org.apache.tomcat:tomcat (Maven): affected from 6.0.0; fixed in 6.0.19\n- org.apache.tomcat:tomcat (Maven): affected from 6.0.0; fixed in 6.0.19\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-2009-0580/ (Markdown: https://insights.sbomify.com/CVE-2009-0580/index.md)","id":"CVE-2009-0580","markdown":"https://insights.sbomify.com/CVE-2009-0580/index.md","name":"CVE-2009-0580","record":{"aliases":["GHSA-w227-xcfx-3pj8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Remote attackers can enumerate valid usernames in Apache Tomcat when FORM authentication is enabled, due to improper error handling in specific authentication realms.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:N/A:N","version":"2.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18, when FORM authentication is used, allows remote attackers to enumerate valid usernames via requests to /j_security_check with malformed URL encoding of passwords, related to improper error checking in the (1) MemoryRealm, (2) DataSourceRealm, and (3) JDBCRealm authentication realms, as demonstrated by a % (percent) value for the j_password parameter.","ecosystems":["Maven"],"exploits":{"exploitdb":1,"first_seen":"2009-06-03","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2009-06-03","kind":"exploitdb","ref":"33023","stars":null,"title":"Apache Tomcat 6.0.18 -
