Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-5735 in the wild since at least 3 Nov 2021.\n\nAffected product: Amcrest. 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-2020-5735/ (Markdown: https://insights.sbomify.com/CVE-2020-5735/index.md)","id":"CVE-2020-5735","markdown":"https://insights.sbomify.com/CVE-2020-5735/index.md","name":"CVE-2020-5735","record":{"aliases":["GHSA-q9mh-3fx2-4gj3"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Amcrest camera/NVR","requires_auth":"low_privilege","summary":"An authenticated remote attacker can trigger a stack-based buffer overflow in Amcrest cameras and NVRs to crash the device or execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"1080-lite_8ch_firmware","vendor":"amcrest"},{"product":"amdv10814-h5_firmware","vendor":"amcrest"},{"product":"ip2m-841-v3_firmware","vendor":"amcrest"},{"product":"ip2m-841_firmware","vendor":"amcrest"},{"product":"ip2m-853ew_firmware","vendor":"amcrest"},{"product":"ip2m-858w_firmware","vendor":"amcrest"},{"product":"ip2m-866ew_firmware","vendor":"amcrest"},{"product":"ip2m-866w_firmware","vendor":"amcrest"},{"product":"ip4m-1053ew_firmware","vendor":"amcrest"},{"product":"ip8m-2454ew_firmware","vendor":"amcrest"},{"product":"ip8m-2493eb_firmware","vendor":"amcrest"},{"product":"ip8m-2496eb_firmware","vendor":"amcrest"},{"product":"ip8m-2597e_firmware","vendor":"amcrest"},{"product":"ip8m-mb2546ew_firmware","vendor":"amcrest"},{"product":"ip8m-mt2544ew_firmware","vendor":"amcrest"},{"product":"ip8m-t2499ew_firmware","vendor":"amcrest"},{"product":"ipm-721_firmware","vendor":"amcrest"},{"product":"ipm-hx1_firmware","vendor":"amcrest"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","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":"Amcrest cameras and NVR are vulnerable to a stack-based buffer overflow over port 37777.
