An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-25239 and fix it if it is affected.\n\nWhat it is: CVE-2019-25239 is a high-severity vulnerability in Guangzhou V-SOLUTION Electronic Technology GPON/EPON OLT Platform, published on 24 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-2019-25239 exists.\n\nAffected product: Guangzhou V-SOLUTION Electronic Technology GPON/EPON OLT Platform. 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-2019-25239/ (Markdown: https://insights.sbomify.com/CVE-2019-25239/index.md)","id":"CVE-2019-25239","markdown":"https://insights.sbomify.com/CVE-2019-25239/index.md","name":"CVE-2019-25239","record":{"aliases":["GHSA-43qf-qj5j-5r47"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"GPON/EPON OLT Platform","requires_auth":"none","summary":"Attackers can download sensitive configuration files from V-SOL OLT devices without authentication, potentially leading to system access.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"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-552","name":"Files or Directories Accessible to External Parties"}],"description":"V-SOL GPON/EPON OLT Platform 2.03 contains an unauthenticated information disclosure vulnerability that allows attackers to download configuration files via direct object reference.
