Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-39435 in the wild and no public exploit code.\n\nAffected product: Zavio IP Camera B8220. 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-2023-39435/ (Markdown: https://insights.sbomify.com/CVE-2023-39435/index.md)","id":"CVE-2023-39435","markdown":"https://insights.sbomify.com/CVE-2023-39435/index.md","name":"CVE-2023-39435","record":{"aliases":["GHSA-75fp-j7f7-j7j8"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Zavio IP Camera","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary code on Zavio IP cameras due to a stack-based buffer overflow in network request handling.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"b8220_firmware","vendor":"zavio"},{"product":"b8520_firmware","vendor":"zavio"},{"product":"cb3211_firmware","vendor":"zavio"},{"product":"cb3212_firmware","vendor":"zavio"},{"product":"cb5220_firmware","vendor":"zavio"},{"product":"cb6231_firmware","vendor":"zavio"},{"product":"cd321_firmware","vendor":"zavio"},{"product":"cf7201_firmware","vendor":"zavio"},{"product":"cf7300_firmware","vendor":"zavio"},{"product":"cf7500_firmware","vendor":"zavio"},{"product":"cf7501_firmware","vendor":"zavio"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Zavio CF7500, CF7300, CF7201, CF7501, CB3211, CB3212, CB5220,\n CB6231, B8520, B8220, and CD321 IP Cameras \n\nwith firmware version M2.1.6.05 are \nvulnerable to stack-based overflows.
