An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-35402 exists.\n\nAffected product: PROLiNK PRC2402M. 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-2021-35402/ (Markdown: https://insights.sbomify.com/CVE-2021-35402/index.md)","id":"CVE-2021-35402","markdown":"https://insights.sbomify.com/CVE-2021-35402/index.md","name":"CVE-2021-35402","record":{"aliases":["GHSA-68g8-2724-hq79"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PROLiNK router","requires_auth":"none","summary":"An attacker can execute arbitrary OS commands on PROLiNK PRC2402M routers via the satellite_status ip parameter.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/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":"PROLiNK PRC2402M 20190909 before 2021-06-13 allows live_api.cgi?page=satellite_list OS command injection via shell metacharacters in the ip parameter (for satellite_status).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Command injection in PRC2402M","id":"CVE-2021-35402","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"File upload in n/a","id":"CVE-2021-35413"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2021-35397"},"products":["PRC2402M"],"published":"2026-02-20","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-23","vendors":["PROLiNK"]},"summary":"An attacker can execute arbitrary OS commands on PROLiNK PRC2402M routers via the satellite_status ip parameter.","url":"https://insights.sbomify.com/CVE-2021-35402/"}
