An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-14500 and fix it if it is affected.\n\nWhat it is: CVE-2020-14500 is a critical vulnerability in Secomea GateManager all versions prior to 9.2c, published on 25 Aug 2020. 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-2020-14500 in the wild and no public exploit code.\n\nAffected product: Secomea GateManager all versions prior to 9.2c. 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-2020-14500/ (Markdown: https://insights.sbomify.com/CVE-2020-14500/index.md)","id":"CVE-2020-14500","markdown":"https://insights.sbomify.com/CVE-2020-14500/index.md","name":"CVE-2020-14500","record":{"aliases":["GHSA-q46g-g86v-m5qx"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ICS remote access","requires_auth":"none","summary":"An attacker can exploit improper null byte handling to overwrite arbitrary data or cause denial of service in Secomea GateManager.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"gatemanager_8250_firmware","vendor":"secomea"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-158","name":"Improper Neutralization of Null Byte or NUL Character"}],"description":"Secomea GateManager all versions prior to 9.2c, An attacker can send a negative value and overwrite arbitrary data.","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":"IMPROPER NEUTRALIZATION OF NULL BYTE OR NUL CHARACTER CWE-158","id":"CVE-2020-14500","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in Advantech iView","id":"CVE-2020-14501"},"packages":[],"prev":{"headline":"Missing authorization in Advantech iView","id":"CVE-2020-14499"},"products":["Secomea GateManager all versions prior to 9.2c"],"published":"2020-08-25","related":[{"cvss_score":9.8,"headline":"OFF-BY-ONE ERROR CWE-193","id":"CVE-2020-14510","kev_date_added":null,"published":"2020-08-25"},{"cvss_score":8.4,"headline":"Add integrity check of GateManager firmware","id":"CVE-2020-29032","kev_date_added":null,"published":"2021-03-05"},{"cvss_score":8.1,"headline":"OFF-BY-ONE ERROR CWE-193","id":"CVE-2020-14508","kev_date_added":null,"published":"2020-08-25"},{"cvss_score":8.1,"headline":"USE OF PASSWORD HASH WITH INSUFFICIENT COMPUTATIONAL EFFORT CWE-916","id":"CVE-2020-14512","kev_date_added":null,"published":"2020-08-25"},{"cvss_score":3.7,"headline":"GateManager does not enforce strict hostname matching for WEB server","id":"CVE-2021-32004","kev_date_added":null,"published":"2021-11-22"}],"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":"2024-09-17","vendors":["Secomea GateManager all versions prior to 9.2c"]},"summary":"An attacker can exploit improper null byte handling to overwrite arbitrary data or cause denial of service in Secomea GateManager.","url":"https://insights.sbomify.com/CVE-2020-14500/"}
