An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-45423 and fix it if it is affected.\n\nWhat it is: CVE-2022-45423 is a high-severity vulnerability in DSS Professional, DSS Express, DHI-DSS7016D-S2/DHI-DSS7016DR-S2, DHI-DSS4004-S2, published on 27 Dec 2022. 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-2022-45423 in the wild and no public exploit code.\n\nAffected product: DSS Professional, DSS Express, DHI-DSS7016D-S2/DHI-DSS7016DR-S2, DHI-DSS4004-S2. 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-2022-45423/ (Markdown: https://insights.sbomify.com/CVE-2022-45423/index.md)","id":"CVE-2022-45423","markdown":"https://insights.sbomify.com/CVE-2022-45423/index.md","name":"CVE-2022-45423","record":{"aliases":["GHSA-gqwx-q2cx-gx28"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Dahua DSS software","requires_auth":"none","summary":"An unauthenticated attacker can obtain encrypted MQTT credentials by sending a crafted packet to the vulnerable interface.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dahua","cpe":[{"product":"dhi-dss4004-s2_firmware","vendor":"dahuasecurity"},{"product":"dhi-dss7016d-s2_firmware","vendor":"dahuasecurity"},{"product":"dhi-dss7016dr-s2_firmware","vendor":"dahuasecurity"},{"product":"dss_express","vendor":"dahuasecurity"},{"product":"dss_professional","vendor":"dahuasecurity"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-306","name":"Missing Authentication for Critical Functionality"}],"description":"Some Dahua software products have a vulnerability of unauthenticated request of MQTT credentials.
