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-2017-0921 in the wild and no public exploit code.\n\nAffected product: Gitlab Gitlab. 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-2017-0921/ (Markdown: https://insights.sbomify.com/CVE-2017-0921/index.md)","id":"CVE-2017-0921","markdown":"https://insights.sbomify.com/CVE-2017-0921/index.md","name":"CVE-2017-0921","record":{"aliases":["GHSA-r86w-x85m-w6rj","MINI-j6hv-3f53-55rc","MINI-xffp-wwfc-27f7","UBUNTU-CVE-2017-0921"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab","requires_auth":"none","summary":"GitLab allows unverified password changes, enabling account takeover if a victim's session is compromised.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"gitlab","vendor":"gitlab"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-640","name":"Weak Password Recovery Mechanism for Forgotten Password"}],"description":"GitLab Community and Enterprise Editions before 10.1.6, 10.2.6, and 10.3.4 are vulnerable to an unverified password change issue in the PasswordsController component resulting in potential account takeover if a victim's session is compromised.","ecosystems":[],"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":"Auth bypass in n/a","id":"CVE-2017-0921","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gitlab:gitlab","products":["gitlab:gitlab"],"type":"auth_bypass","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in GitLab Community and Enterprise Editions","id":"CVE-2017-0922"},"packages":[],"prev":{"headline":"Missing authorization in GitLab Community and Enterprise Editions","id":"CVE-2017-0920"},"products":["n/a"],"published":"2018-07-03","related":[{"cvss_score":10,"headline":"GitLab Community Edition and Enterprise Edition Integer Overflow or Wraparound","id":"CVE-2026-97229","kev_date_added":"2026-10-29","published":"2026-10-13"},{"cvss_score":10,"headline":"GitLab Community Edition and Enterprise Edition Path Traversal","id":"CVE-2026-85706","kev_date_added":"2026-09-11","published":"2026-09-12"},{"cvss_score":10,"headline":"GitLab Community and Enterprise Editions Improper Access Control","id":"CVE-2023-7028","kev_date_added":"2024-05-01","published":"2024-01-12"},{"cvss_score":10,"headline":"GitLab Community and Enterprise Editions Remote Code Execution","id":"CVE-2021-22205","kev_date_added":"2021-11-03","published":"2021-04-23"},{"cvss_score":6.8,"headline":"GitLab Community and Enterprise Editions Server-Side Request Forgery (SSRF)","id":"CVE-2021-39935","kev_date_added":"2026-02-03","published":"2021-12-13"},{"cvss_score":6.8,"headline":"GitLab Server-Side Request Forgery (SSRF)","id":"CVE-2021-22175","kev_date_added":"2026-02-18","published":"2021-06-11"},{"cvss_score":10,"headline":"Integer Overflow or Wraparound in GitLab","id":"CVE-2026-110264","kev_date_added":null,"published":"2026-10-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-09-17","vendors":["n/a"]},"summary":"GitLab allows unverified password changes, enabling account takeover if a victim's session is compromised.","url":"https://insights.sbomify.com/CVE-2017-0921/"}
