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-2010-3494 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pyftpdlib (PyPI): affected all versions; fixed in 0.5.2\n- pyftpdlib (PyPI): affected all versions; fixed in 0.5.2\n- pyftpdlib (PyPI): affected all versions; fixed in 0.5.2\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-2010-3494/ (Markdown: https://insights.sbomify.com/CVE-2010-3494/index.md)","id":"CVE-2010-3494","markdown":"https://insights.sbomify.com/CVE-2010-3494/index.md","name":"CVE-2010-3494","record":{"aliases":["DEBIAN-CVE-2010-3494","GHSA-hw4g-fhcp-x5mq","PYSEC-2010-11","UBUNTU-CVE-2010-3494"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python FTP library","requires_auth":"none","summary":"Remote attackers can cause a denial of service in pyftpdlib by rapidly opening and closing TCP connections, exploiting a race condition in the FTP handler.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pyftpdlib","vendor":"g.rodola"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"Race condition in the FTPHandler class in ftpserver.py in pyftpdlib before 0.5.2 allows remote attackers to cause a denial of service (daemon outage) by establishing and then immediately closing a TCP connection, leading to the accept function having an unexpected value of None for the address, or an ECONNABORTED, EAGAIN, or EWOULDBLOCK error, a related issue to CVE-2010-3492.","ecosystems":["PyPI"],"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":"Concurrent Execution using Shared Resource with Improper Synchronization in pyftpdlib","id":"CVE-2010-3494","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"race_condition","year":"2010"},"n_packages":3,"n_references":11,"next":{"headline":"Zope Object Database Denial of Service vulnerability","id":"CVE-2010-3495"},"packages":[{"ecosystem":"PyPI","fixed":["0.5.2"],"introduced":["0"],"last_affected":[],"package":"pyftpdlib","purl":null,"source":"GHSA-hw4g-fhcp-x5mq"},{"ecosystem":"PyPI","fixed":["0.5.2"],"introduced":["0"],"last_affected":[],"package":"pyftpdlib","purl":"pkg:pypi/pyftpdlib","source":"GHSA-hw4g-fhcp-x5mq"},{"ecosystem":"PyPI","fixed":["0.5.2"],"introduced":["0"],"last_affected":[],"package":"pyftpdlib","purl":"pkg:pypi/pyftpdlib","source":"PYSEC-2010-11"}],"prev":{"headline":"Race condition in n/a","id":"CVE-2010-3493"},"products":["n/a"],"published":"2010-10-19","related":[{"cvss_score":7.5,"headline":"Improper Authentication in pyftpdlib","id":"CVE-2007-6737","kev_date_added":null,"published":"2010-10-19"},{"cvss_score":7.5,"headline":"Improper Authentication in pyftpdlib","id":"CVE-2008-7263","kev_date_added":null,"published":"2010-10-19"},{"cvss_score":6.5,"headline":"Directory Traversal in pyftpdlib","id":"CVE-2007-6736","kev_date_added":null,"published":"2010-10-19"},{"cvss_score":6.5,"headline":"Improper privilege management in pyftpdlib","id":"CVE-2007-6741","kev_date_added":null,"published":"2010-10-19"},{"cvss_score":6.5,"headline":"Directory traversal in pyftpdlib","id":"CVE-2008-7262","kev_date_added":null,"published":"2010-10-19"},{"cvss_score":5,"headline":"pyftpdlib Use of Insufficiently Random Values of port selection on PASV command","id":"CVE-2007-6738","kev_date_added":null,"published":"2010-10-19"},{"cvss_score":5,"headline":"Improper Input Validation in pyftpdlib","id":"CVE-2007-6739","kev_date_added":null,"published":"2010-10-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service in pyftpdlib by rapidly opening and closing TCP connections, exploiting a race condition in the FTP handler.","url":"https://insights.sbomify.com/CVE-2010-3494/"}
