Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2017-20221 exists.\n\nAffected product: Telesquare SDT-CS3B1. 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-2017-20221/ (Markdown: https://insights.sbomify.com/CVE-2017-20221/index.md)","id":"CVE-2017-20221","markdown":"https://insights.sbomify.com/CVE-2017-20221/index.md","name":"CVE-2017-20221","record":{"aliases":["GHSA-98cj-p4cp-mf8h"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"LTE router","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary system commands on Telesquare LTE routers via CSRF, leading to full device compromise.","user_interaction":"not_required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"sdt-cs3b1_firmware","vendor":"telesquare"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Telesquare SKT LTE Router SDT-CS3B1 version 1.2.0 contains a cross-site request forgery vulnerability that allows authenticated attackers to execute arbitrary system commands by exploiting missing request validation.
