An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-28775 and fix it if it is affected.\n\nWhat it is: CVE-2026-28775 is a critical command injection vulnerability in International Datacasting Corporation (IDC) SFX2100 Series SuperFlex SatelliteReceiver, published on 4 Mar 2026. 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-2026-28775 in the wild and no public exploit code.\n\nAffected product: International Datacasting Corporation (IDC) SFX2100 Series SuperFlex SatelliteReceiver. 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-2026-28775/ (Markdown: https://insights.sbomify.com/CVE-2026-28775/index.md)","id":"CVE-2026-28775","markdown":"https://insights.sbomify.com/CVE-2026-28775/index.md","name":"CVE-2026-28775","record":{"aliases":["GHSA-rvxp-rc2j-v2h6"],"analysis":{"component_type":"iot_embedded","fix_type":"configuration_change","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Satellite Receiver","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary commands with root privileges on IDC SuperFlex Satellite Receivers due to default writable SNMP community strings.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gridware","cpe":[{"product":"sfx2100_firmware","vendor":"datacast"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"An unauthenticated Remote Code Execution (RCE) vulnerability exists in the SNMP service of International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver.
