Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-5738 and fix it if it is affected.\n\nWhat it is: CVE-2020-5738 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-2020-5738 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-2020-5738/ (Markdown: https://insights.sbomify.com/CVE-2020-5738/index.md)","id":"CVE-2020-5738","markdown":"https://insights.sbomify.com/CVE-2020-5738/index.md","name":"CVE-2020-5738","record":{"aliases":["GHSA-h368-4vc2-fv34"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"VoIP phone firmware","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary commands on Grandstream GXP1600 phones by uploading a malicious tar file via the VPN upload interface.","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-59","name":"Improper Link Resolution Before File Access"}],"description":"Grandstream GXP1600 series firmware 1.0.4.152 and below is vulnerable to authenticated remote command execution when an attacker uploads a specially crafted tar file to the HTTP /cgi-bin/upload_vpntar interface.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Command injection in Grandstream GXP1600 Series","id":"CVE-2020-5738","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in Grandstream GXP1600 Series","id":"CVE-2020-5739"},"packages":[],"prev":{"headline":"Cross-site scripting in Tenable.Sc","id":"CVE-2020-5737"},"products":["Grandstream GXP1600 Series"],"published":"2020-04-14","related":[{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2018-17564","kev_date_added":null,"published":"2019-04-01"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2018-17565","kev_date_added":null,"published":"2019-04-01"},{"cvss_score":9.3,"headline":"Grandstream GXP1600 VoIP Phones - Unauthenticated stack buffer overflow","id":"CVE-2026-2329","kev_date_added":null,"published":"2026-02-18"},{"cvss_score":8.8,"headline":"Command injection in Grandstream GXP1600 Series","id":"CVE-2020-5739","kev_date_added":null,"published":"2020-04-14"},{"cvss_score":5.3,"headline":"Information disclosure in n/a","id":"CVE-2018-17563","kev_date_added":null,"published":"2019-04-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Authenticated attackers can execute arbitrary commands on Grandstream GXP1600 phones by uploading a malicious tar file via the VPN upload interface.","url":"https://insights.sbomify.com/CVE-2020-5738/"}
