Guangzhou Hefeng Automation Technology Co., Ltd. QiHang Media Web 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-2020-36899 exists.\n\nAffected product: Shenzhen Xingmeng Qihang Media Co., Ltd. Guangzhou Hefeng Automation Technology Co., Ltd. QiHang Media Web 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-2020-36899/ (Markdown: https://insights.sbomify.com/CVE-2020-36899/index.md)","id":"CVE-2020-36899","markdown":"https://insights.sbomify.com/CVE-2020-36899/index.md","name":"CVE-2020-36899","record":{"aliases":["GHSA-2fqg-hhc5-9x33"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Digital Signage Software","requires_auth":"none","summary":"Remote attackers can read arbitrary files and directory contents without authentication by manipulating parameters in the QH.aspx endpoint.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"qihang_media_web_digital_signage","vendor":"howfor"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-530","name":"Exposure of Backup File to an Unauthorized Control Sphere"}],"description":"QiHang Media Web Digital Signage 3.0.9 contains an unauthenticated file disclosure vulnerability that allows remote attackers to access sensitive files through unverified 'filename' and 'path' parameters.
