An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-25361 exists.\n\nAffected product: Ayukov NFTP client. 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-2019-25361/ (Markdown: https://insights.sbomify.com/CVE-2019-25361/index.md)","id":"CVE-2019-25361","markdown":"https://insights.sbomify.com/CVE-2019-25361/index.md","name":"CVE-2019-25361","record":{"aliases":["GHSA-64gc-33j4-53f4"],"analysis":{"component_type":"desktop_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"NFTP client","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Ayukov NFTP client via a buffer overflow in SYST command handling.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/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":"Ayukov NFTP client 1.71 contains a buffer overflow vulnerability in the SYST command handling that allows remote attackers to execute arbitrary code.
