Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-5739 and fix it if it is affected.\n\nWhat it is: CVE-2020-5739 is a high-severity command injection vulnerability in Grandstream GXP1600 Series, published on 14 Apr 2020. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-5739 in the wild and no public exploit code.\n\nAffected product: Grandstream GXP1600 Series. 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-2020-5739/ (Markdown: https://insights.sbomify.com/CVE-2020-5739/index.md)","id":"CVE-2020-5739","markdown":"https://insights.sbomify.com/CVE-2020-5739/index.md","name":"CVE-2020-5739","record":{"aliases":["GHSA-6p3v-7x9x-66jr"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"VoIP phone firmware","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary commands with root privileges on Grandstream GXP1600 phones by injecting scripts into VPN settings.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"gxp1610_firmware","vendor":"grandstream"},{"product":"gxp1615_firmware","vendor":"grandstream"},{"product":"gxp1620_firmware","vendor":"grandstream"},{"product":"gxp1625_firmware","vendor":"grandstream"},{"product":"gxp1628_firmware","vendor":"grandstream"},{"product":"gxp1630_firmware","vendor":"grandstream"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Grandstream GXP1600 series firmware 1.0.4.152 and below is vulnerable to authenticated remote command execution when an attacker adds an OpenVPN up script to the phone's VPN settings via the \"Additional Settings\" field in the web interface.
