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-2021-22640 in the wild and no public exploit code.\n\nAffected product: Ovarro TBox. 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-2021-22640/ (Markdown: https://insights.sbomify.com/CVE-2021-22640/index.md)","id":"CVE-2021-22640","markdown":"https://insights.sbomify.com/CVE-2021-22640/index.md","name":"CVE-2021-22640","record":{"aliases":["GHSA-4ch8-jgqc-v66p"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Ovarro TBox","requires_auth":"none","summary":"Attackers can decrypt login passwords via communication capture and brute force, leading to unauthorized access to Ovarro TBox devices.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"tbox_lt2-530_firmware","vendor":"ovarro"},{"product":"tbox_lt2-532_firmware","vendor":"ovarro"},{"product":"tbox_lt2-540_firmware","vendor":"ovarro"},{"product":"tbox_ms-cpu32-s2_firmware","vendor":"ovarro"},{"product":"tbox_ms-cpu32_firmware","vendor":"ovarro"},{"product":"tbox_rm2_firmware","vendor":"ovarro"},{"product":"tbox_tg2_firmware","vendor":"ovarro"},{"product":"twinsoft","vendor":"ovarro"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"},{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"},{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"An attacker can decrypt the Ovarro TBox login password by communication capture and brute force attacks.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Ovarro TBox Insufficiently Protected Credentials","id":"CVE-2021-22640","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Tellus Lite V-Simulator and V-Server Lite","id":"CVE-2021-22641"},"packages":[],"prev":{"headline":"Memory corruption in Tellus Lite V-Simulator and V-Server Lite","id":"CVE-2021-22639"},"products":["TBox"],"published":"2022-07-28","related":[{"cvss_score":8.8,"headline":"Ovarro TBox Code Injection","id":"CVE-2021-22646","kev_date_added":null,"published":"2022-07-28"},{"cvss_score":8.8,"headline":"Ovarro TBox Incorrect Permission Assignment for Critical Resource","id":"CVE-2021-22648","kev_date_added":null,"published":"2022-07-28"},{"cvss_score":7.5,"headline":"Ovarro TBox Uncontrolled Resource Consumption","id":"CVE-2021-22642","kev_date_added":null,"published":"2022-07-28"},{"cvss_score":7.5,"headline":"Ovarro TBox Use of Hard-coded Cryptographic Key","id":"CVE-2021-22644","kev_date_added":null,"published":"2022-07-28"},{"cvss_score":7.5,"headline":"Ovarro TBox Relative Path Traversal","id":"CVE-2021-22650","kev_date_added":null,"published":"2022-07-28"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-17","vendors":["Ovarro"]},"summary":"Attackers can decrypt login passwords via communication capture and brute force, leading to unauthorized access to Ovarro TBox devices.","url":"https://insights.sbomify.com/CVE-2021-22640/"}
