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-2023-6764 in the wild and no public exploit code.\n\nAffected product: Zyxel ATP series firmware. 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-2023-6764/ (Markdown: https://insights.sbomify.com/CVE-2023-6764/index.md)","id":"CVE-2023-6764","markdown":"https://insights.sbomify.com/CVE-2023-6764/index.md","name":"CVE-2023-6764","record":{"aliases":["GHSA-83ff-cpf7-ghwf"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Zyxel firewall firmware","requires_auth":"none","summary":"A format string vulnerability in Zyxel ATP and USG FLEX firmware allows remote code execution via crafted payloads, requiring specific memory layout knowledge.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"atp100_firmware","vendor":"zyxel"},{"product":"atp100w_firmware","vendor":"zyxel"},{"product":"atp200_firmware","vendor":"zyxel"},{"product":"atp500_firmware","vendor":"zyxel"},{"product":"atp700_firmware","vendor":"zyxel"},{"product":"atp800_firmware","vendor":"zyxel"},{"product":"usg20-vpn_firmware","vendor":"zyxel"},{"product":"usg20w-vpn_firmware","vendor":"zyxel"},{"product":"usg_flex_100_firmware","vendor":"zyxel"},{"product":"usg_flex_100ax_firmware","vendor":"zyxel"},{"product":"usg_flex_100h_firmware","vendor":"zyxel"},{"product":"usg_flex_100w_firmware","vendor":"zyxel"},{"product":"usg_flex_200_firmware","vendor":"zyxel"},{"product":"usg_flex_200h_firmware","vendor":"zyxel"},{"product":"usg_flex_200hp_firmware","vendor":"zyxel"},{"product":"usg_flex_500_firmware","vendor":"zyxel"},{"product":"usg_flex_500h_firmware","vendor":"zyxel"},{"product":"usg_flex_50_firmware","vendor":"zyxel"},{"product":"usg_flex_50w_firmware","vendor":"zyxel"},{"product":"usg_flex_700_firmware","vendor":"zyxel"},{"product":"usg_flex_700h_firmware","vendor":"zyxel"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"}],"description":"A format string vulnerability in a function of the IPSec VPN feature in Zyxel ATP series firmware versions from 4.32 through 5.37 Patch 1, USG FLEX series firmware versions from 4.50 through 5.37 Patch 1, USG FLEX 50(W) series firmware versions from 4.16 through 5.37 Patch 1, and USG20(W)-VPN series firmware versions from 4.16 through 5.37 Patch 1 could allow an attacker to achieve unauthorized remote code execution by sending a sequence of specially crafted payloads containing an invalid pointer;
