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-2020-9527 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-9527/ (Markdown: https://insights.sbomify.com/CVE-2020-9527/index.md)","id":"CVE-2020-9527","markdown":"https://insights.sbomify.com/CVE-2020-9527/index.md","name":"CVE-2020-9527","record":{"aliases":["GHSA-w59r-wjpf-fgqc"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"IoT camera firmware","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary code via a buffer overflow in the P2P service of millions of IoT devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"shenzhen_hichip_vision_technology_firmware","vendor":"hichip"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Firmware developed by Shenzhen Hichip Vision Technology (V6 through V20, after 2018-08-09 through 2020), as used by many different vendors in millions of Internet of Things devices, suffers from buffer overflow vulnerability that allows unauthenticated remote attackers to execute arbitrary code via the peer-to-peer (P2P) service.
