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-2013-5123 exists.\n\nAffected packages and fixed versions:\n- pip (PyPI): affected all versions; fixed in 1.5\n- pip (PyPI): affected all versions; fixed in 1.5\n- pip (PyPI): affected all versions; fixed in 1.5\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-2013-5123/ (Markdown: https://insights.sbomify.com/CVE-2013-5123/index.md)","id":"CVE-2013-5123","markdown":"https://insights.sbomify.com/CVE-2013-5123/index.md","name":"CVE-2013-5123","record":{"aliases":["CVE-2013-4266","DEBIAN-CVE-2013-5123","GHSA-c5h8-cq4v-cvfm","MGASA-2015-0180","PYSEC-2019-160"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Python package installer","requires_auth":"none","summary":"Attackers can perform man-in-the-middle attacks on pip mirror downloads, potentially leading to code execution or data theft.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"pip","vendor":"pypa"},{"product":"openshift","vendor":"redhat"},{"product":"software_collections","vendor":"redhat"},{"product":"virtualenv","vendor":"virtualenv"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The mirroring support (-M, --use-mirrors) in Python Pip before 1.5 uses insecure DNS querying and authenticity checks which allows attackers to perform man-in-the-middle attacks.","ecosystems":["PyPI"],"exploits":{"exploitdb":1,"first_seen":"2013-01-13","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2013-01-13","kind":"exploitdb","ref":"24086","stars":null,"title":"phlyLabs phlyMail Lite 4.03.04 - 'go' Open Redirect"}],"tier":"weaponised"},"has_fix":true,"headline":"Improper Authentication in pip","id":"CVE-2013-5123","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora","redhat:openshift","redhat:software_collections"],"type":"security_feature_bypass","year":"2013"},"n_packages":3,"n_references":8,"next":{"headline":"Memory corruption in n/a","id":"CVE-2013-5125"},"packages":[{"ecosystem":"PyPI","fixed":["1.5"],"introduced":["0"],"last_affected":[],"package":"pip","purl":null,"source":"GHSA-c5h8-cq4v-cvfm"},{"ecosystem":"PyPI","fixed":["1.5"],"introduced":["0"],"last_affected":[],"package":"pip","purl":"pkg:pypi/pip","source":"GHSA-c5h8-cq4v-cvfm"},{"ecosystem":"PyPI","fixed":["1.5"],"introduced":["0"],"last_affected":[],"package":"pip","purl":"pkg:pypi/pip","source":"PYSEC-2019-160"}],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2013-5122"},"products":["n/a"],"published":"2019-11-05","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Attackers can perform man-in-the-middle attacks on pip mirror downloads, potentially leading to code execution or data theft.","url":"https://insights.sbomify.com/CVE-2013-5123/"}
