An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-24705 and fix it if it is affected.\n\nWhat it is: CVE-2022-24705 is a critical memory corruption vulnerability in https://accel-ppp.org/ accel-ppp, published on 14 Feb 2022. 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-2022-24705 in the wild and no public exploit code.\n\nAffected product: https://accel-ppp.org/ accel-ppp. 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-2022-24705/ (Markdown: https://insights.sbomify.com/CVE-2022-24705/index.md)","id":"CVE-2022-24705","markdown":"https://insights.sbomify.com/CVE-2022-24705/index.md","name":"CVE-2022-24705","record":{"aliases":["GHSA-8hhg-rh8g-2x9h"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PPPoE server software","requires_auth":"none","summary":"A buffer overflow in accel-ppp allows remote attackers to execute arbitrary code via crafted IPv6 prefix attribute requests.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GovTech CSG","cpe":[{"product":"accel-ppp","vendor":"accel-ppp"}],"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":"The rad_packet_recv function in radius/packet.c suffers from a memcpy buffer overflow, resulting in an overly-large recvfrom into a fixed buffer that causes a buffer overflow and overwrites arbitrary memory.
