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-2013-1895 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- py-bcrypt (PyPI): affected all versions; fixed in 0.3\n- py-bcrypt (PyPI): affected all versions; fixed in 0.3\n- py-bcrypt (PyPI): affected all versions; fixed in 0.3\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-2013-1895/ (Markdown: https://insights.sbomify.com/CVE-2013-1895/index.md)","id":"CVE-2013-1895","markdown":"https://insights.sbomify.com/CVE-2013-1895/index.md","name":"CVE-2013-1895","record":{"aliases":["DEBIAN-CVE-2013-1895","GHSA-r838-q6jp-58xx","PYSEC-2020-249"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Python bcrypt library","requires_auth":"none","summary":"Attackers can bypass authentication in the py-bcrypt library by exploiting a race condition that overwrites password hashes during concurrent requests.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"py-bcrypt","vendor":"python"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"The py-bcrypt module before 0.3 for Python does not properly handle concurrent memory access, which allows attackers to bypass authentication via multiple authentication requests, which trigger the password hash to be overwritten.","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":"Improper Restriction of Excessive Authentication Attempts in py-bcrypt","id":"CVE-2013-1895","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"race_condition","year":"2013"},"n_packages":3,"n_references":5,"next":{"headline":"Denial of service in n/a","id":"CVE-2013-1896"},"packages":[{"ecosystem":"PyPI","fixed":["0.3"],"introduced":["0"],"last_affected":[],"package":"py-bcrypt","purl":null,"source":"GHSA-r838-q6jp-58xx"},{"ecosystem":"PyPI","fixed":["0.3"],"introduced":["0"],"last_affected":[],"package":"py-bcrypt","purl":"pkg:pypi/py-bcrypt","source":"GHSA-r838-q6jp-58xx"},{"ecosystem":"PyPI","fixed":["0.3"],"introduced":["0"],"last_affected":[],"package":"py-bcrypt","purl":"pkg:pypi/py-bcrypt","source":"PYSEC-2020-249"}],"prev":{"headline":"SQL injection in n/a","id":"CVE-2013-1893"},"products":["py-bcrypt"],"published":"2020-01-28","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"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":"2024-08-06","vendors":["py-bcrypt"]},"summary":"Attackers can bypass authentication in the py-bcrypt library by exploiting a race condition that overwrites password hashes during concurrent requests.","url":"https://insights.sbomify.com/CVE-2013-1895/"}
