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-2018-7539 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-7539/ (Markdown: https://insights.sbomify.com/CVE-2018-7539/index.md)","id":"CVE-2018-7539","markdown":"https://insights.sbomify.com/CVE-2018-7539/index.md","name":"CVE-2018-7539","record":{"aliases":["GHSA-5x2r-g3pj-8qhq"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Appear TV set-top box","requires_auth":"none","summary":"Attackers can read arbitrary OS files via path traversal in the Maintenance Center web server, potentially leading to full device compromise.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"xc5000_firmware","vendor":"appeartv"},{"product":"xc5100_firmware","vendor":"appeartv"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"On Appear TV XC5000 and XC5100 devices with firmware 3.26.217, it is possible to read OS files with a specially crafted HTTP request (such as GET /../../../../../../../../../../../../etc/passwd) to the web server (fuzzd/0.1.1) running the Maintenance Center on port TCP/8088.
