An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2024-39950 and fix it if it is affected.\n\nWhat it is: CVE-2024-39950 is a high-severity vulnerability in Dahua NVR4XXX and IPC-HX8XXX, published on 31 Jul 2024. 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-2024-39950 in the wild and no public exploit code.\n\nAffected product: Dahua NVR4XXX and IPC-HX8XXX. 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-2024-39950/ (Markdown: https://insights.sbomify.com/CVE-2024-39950/index.md)","id":"CVE-2024-39950","markdown":"https://insights.sbomify.com/CVE-2024-39950/index.md","name":"CVE-2024-39950","record":{"aliases":["GHSA-x56v-vwr6-4gfg"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Dahua NVR and IPC","requires_auth":"none","summary":"Attackers can send crafted packets to Dahua NVR and IPC devices to trigger device initialization, causing a denial of service.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dahua","cpe":[{"product":"ipc-hfs8449g-z7-led_firmware","vendor":"dahuasecurity"},{"product":"ipc-hfs8849g-z3-led_firmware","vendor":"dahuasecurity"},{"product":"nvr4104-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4104-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4104-p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4104-p-4ks3\\(960g\\)_firmware","vendor":"dahuasecurity"},{"product":"nvr4104-p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4104hs-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4104hs-4ks3\\(960g\\)_firmware","vendor":"dahuasecurity"},{"product":"nvr4104hs-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4104hs-p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4104hs-p-4ks3\\(960g\\)_firmware","vendor":"dahuasecurity"},{"product":"nvr4104hs-p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4108-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4108-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4108-8p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4108-8p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4108-p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4108-p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4108hs-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4108hs-4ks3\\(960g\\)_firmware","vendor":"dahuasecurity"},{"product":"nvr4108hs-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4108hs-8p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4108hs-8p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4108hs-p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4108hs-p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4116-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4116-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4116-8p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4116-8p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4116hs-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4116hs-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4116hs-8p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4116hs-8p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4204-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4204-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4204-p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4204-p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4208-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4208-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4208-8p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4208-8p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4216-16p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4216-16p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4216-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4216-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4232-16p-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4232-16p-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4232-4ks2\\/l_firmware","vendor":"dahuasecurity"},{"product":"nvr4232-4ks3_firmware","vendor":"dahuasecurity"},{"product":"nvr4416-16p-4ks2\\/i_firmware","vendor":"dahuasecurity"},{"product":"nvr4416-4ks2\\/i_firmware","vendor":"dahuasecurity"},{"product":"nvr4432-16p-4ks2\\/i_firmware","vendor":"dahuasecurity"},{"product":"nvr4432-4ks2\\/i_firmware","vendor":"dahuasecurity"},{"product":"nvr4816-16p-4ks2\\/i_firmware","vendor":"dahuasecurity"},{"product":"nvr4816-4ks2\\/i_firmware","vendor":"dahuasecurity"},{"product":"nvr4832-16p-4ks2\\/i_firmware","vendor":"dahuasecurity"},{"product":"nvr4832-4ks2\\/i_firmware","vendor":"dahuasecurity"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A vulnerability has been found in Dahua products.
