SOL GPON/EPON OLT Platform, published on 24 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-25237 exists.\n\nAffected product: Guangzhou V-SOLUTION Electronic Technology Co., Ltd. SOL 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-2019-25237/ (Markdown: https://insights.sbomify.com/CVE-2019-25237/index.md)","id":"CVE-2019-25237","markdown":"https://insights.sbomify.com/CVE-2019-25237/index.md","name":"CVE-2019-25237","record":{"aliases":["GHSA-46cm-29f3-f9rv"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"GPON/EPON OLT Platform","requires_auth":"low_privilege","summary":"Normal users can gain administrative access by manipulating the user role parameter in HTTP requests, requiring immediate patching by network administrators.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"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:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"V-SOL GPON/EPON OLT Platform v2.03 contains a privilege escalation vulnerability that allows normal users to gain administrative access by manipulating the user role parameter.
