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-2025-40634 in the wild and no public exploit code.\n\nAffected product: TP-Link Link Archer AX50. 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-2025-40634/ (Markdown: https://insights.sbomify.com/CVE-2025-40634/index.md)","id":"CVE-2025-40634","markdown":"https://insights.sbomify.com/CVE-2025-40634/index.md","name":"CVE-2025-40634","record":{"aliases":["GHSA-h754-2839-mqvq"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TP-Link router","requires_auth":"none","summary":"A stack-based buffer overflow in the conn-indicator binary allows remote attackers to execute arbitrary code on TP-Link Archer AX50 routers.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCIBE","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Stack-based buffer overflow vulnerability in the 'conn-indicator' binary running as root on the TP-Link Archer AX50 router, in firmware versions prior to 1.0.15 build 241203 rel61480.
