An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-36892 and fix it if it is affected.\n\nWhat it is: CVE-2020-36892 is a critical vulnerability in EIBIZ Co.,Ltd. i-Media Server Digital Signage, published on 10 Dec 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-36892 exists.\n\nAffected product: EIBIZ Co.,Ltd. i-Media Server Digital Signage. 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-2020-36892/ (Markdown: https://insights.sbomify.com/CVE-2020-36892/index.md)","id":"CVE-2020-36892","markdown":"https://insights.sbomify.com/CVE-2020-36892/index.md","name":"CVE-2020-36892","record":{"aliases":["GHSA-gm58-7w8m-7hg4"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Digital Signage Server","requires_auth":"none","summary":"Unauthenticated attackers can escalate privileges and take over accounts by manipulating user roles via the AMF endpoint in Eibiz i-Media Server.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"i-media_server_digital_signage","vendor":"eibiz"}],"cvss":{"score":9.3,"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:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Eibiz i-Media Server Digital Signage 3.8.0 contains an unauthenticated privilege escalation vulnerability in the updateUser object that allows attackers to modify user roles.
