It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2024-27521 and fix it if it is affected.\n\nWhat it is: CVE-2024-27521 is a high-severity command injection vulnerability in Totolink A3300r Firmware, published on 26 Mar 2024. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-27521 in the wild and no public exploit code.\n\nAffected product: Totolink A3300r 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-2024-27521/ (Markdown: https://insights.sbomify.com/CVE-2024-27521/index.md)","id":"CVE-2024-27521","markdown":"https://insights.sbomify.com/CVE-2024-27521/index.md","name":"CVE-2024-27521","record":{"aliases":["GHSA-x3cr-crpx-mg4r"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TOTOLINK router","requires_auth":"low_privilege","summary":"Unauthenticated remote attackers can execute arbitrary system commands as root on TOTOLINK A3300R routers via the setOpModeCfg function.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"a3300r_firmware","vendor":"totolink"}],"cvss":{"score":8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"TOTOLINK A3300R V17.0.0cu.557_B20221024 was discovered to contain an unauthenticated remote command execution (RCE) vulnerability via multiple parameters in the \"setOpModeCfg\" function.
