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-2022-31802 in the wild and no public exploit code.\n\nAffected product: CODESYS Gateway Server V2. 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-2022-31802/ (Markdown: https://insights.sbomify.com/CVE-2022-31802/index.md)","id":"CVE-2022-31802","markdown":"https://insights.sbomify.com/CVE-2022-31802/index.md","name":"CVE-2022-31802","record":{"aliases":["GHSA-jp8v-m2cx-q392"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"CODESYS Gateway Server","requires_auth":"none","summary":"An attacker can bypass authentication in CODESYS Gateway Server by exploiting partial string comparison flaws in password verification.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"gateway","vendor":"codesys"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-187","name":"Partial String Comparison"}],"description":"In CODESYS Gateway Server V2 for versions prior to V2.3.9.38 only a part of the the specified password is been compared to the real CODESYS Gateway password.
