Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2011-0762 exists.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2011-0762/ (Markdown: https://insights.sbomify.com/CVE-2011-0762/index.md)","id":"CVE-2011-0762","markdown":"https://insights.sbomify.com/CVE-2011-0762/index.md","name":"CVE-2011-0762","record":{"aliases":["DEBIAN-CVE-2011-0762","DSA-2305-1","GHSA-jh3r-4mfv-pjv8","RHSA-2011:0337"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"vsftpd FTP server","requires_auth":"low_privilege","summary":"Authenticated remote attackers can cause denial of service in vsftpd via crafted glob expressions in STAT commands, leading to CPU exhaustion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"opensuse","vendor":"opensuse"},{"product":"linux_enterprise_server","vendor":"suse"},{"product":"vsftpd","vendor":"vsftpd_project"}],"cvss":{"score":4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The vsf_filename_passes_filter function in ls.c in vsftpd before 2.3.3 allows remote authenticated users to cause a denial of service (CPU consumption and process slot exhaustion) via crafted glob expressions in STAT commands in multiple FTP sessions, a different vulnerability than CVE-2010-2632.","ecosystems":["Red Hat:enterprise_linux:4::as","Red Hat:enterprise_linux:4::es","Red Hat:enterprise_linux:5::server","Red Hat:enterprise_linux:6::server","Red Hat:enterprise_linux:6::workstation"],"exploits":{"exploitdb":1,"first_seen":"2011-02-03","github_poc":1,"max_poc_stars":0,"metasploit":1,"nuclei":1,"refs":[{"date":"2011-02-03","kind":"metasploit","ref":"auxiliary/dos/ftp/vsftpd_232","stars":null,"title":"VSFTPD 2.3.2 and Earlier STAT Denial of Service"},{"date":"2011-03-02","kind":"exploitdb","ref":"16270","stars":null,"title":"vsftpd 2.3.2 -
