It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-4231 in the wild and no public exploit code.\n\nAffected product: Digisol Router DG-GR1321. 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-2024-4231/ (Markdown: https://insights.sbomify.com/CVE-2024-4231/index.md)","id":"CVE-2024-4231","markdown":"https://insights.sbomify.com/CVE-2024-4231/index.md","name":"CVE-2024-4231","record":{"aliases":["GHSA-7c88-698j-qxf8"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Digisol Router","requires_auth":"none","summary":"An attacker with physical access can bypass authentication via serial interface to gain root shell access and read sensitive information.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-In","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1191","name":"On-Chip Debug and Test Interface With Improper Access Control"}],"description":"This vulnerability exists in Digisol Router (DG-GR1321: Hardware version 3.7L;  Firmware version : v3.2.02) due to presence of root terminal access on a serial interface without proper access control.
