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-2021-42949 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-42949/ (Markdown: https://insights.sbomify.com/CVE-2021-42949/index.md)","id":"CVE-2021-42949","markdown":"https://insights.sbomify.com/CVE-2021-42949/index.md","name":"CVE-2021-42949","record":{"aliases":["DEBIAN-CVE-2021-42949","GHSA-87g3-rx63-rrch","UBUNTU-CVE-2021-42949"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Hotel Management Software","requires_auth":"none","summary":"Attackers can bypass authentication in HotelDruid by brute-forcing predictable session tokens generated by the login function.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"hoteldruid","vendor":"digitaldruid"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The component controlla_login function in HotelDruid Hotel Management Software v3.0.3 generates a predictable session token, allowing attackers to bypass authentication via bruteforce attacks.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2022-02-19","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2022-02-19T21:02:42Z","kind":"github_poc","ref":"https://github.com/dhammon/HotelDruid-CVE-2021-42949","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Auth bypass in n/a","id":"CVE-2021-42949","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Code injection in n/a","id":"CVE-2021-42950"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-42948"},"products":["n/a"],"published":"2022-09-16","related":[{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2023-43371","kev_date_added":null,"published":"2023-09-20"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2023-43373","kev_date_added":null,"published":"2023-09-20"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2023-43374","kev_date_added":null,"published":"2023-09-20"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2023-43375","kev_date_added":null,"published":"2023-09-20"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2021-37832","kev_date_added":null,"published":"2021-08-03"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2019-9086","kev_date_added":null,"published":"2019-06-07"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-06-03","vendors":["n/a"]},"summary":"Attackers can bypass authentication in HotelDruid by brute-forcing predictable session tokens generated by the login function.","url":"https://insights.sbomify.com/CVE-2021-42949/"}
