An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-34049 exists.\n\nAffected product: OptiLink ONT1GEW GPON. 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-2025-34049/ (Markdown: https://insights.sbomify.com/CVE-2025-34049/index.md)","id":"CVE-2025-34049","markdown":"https://insights.sbomify.com/CVE-2025-34049/index.md","name":"CVE-2025-34049","record":{"aliases":["GHSA-53rj-48p2-7m5j"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"GPON router","requires_auth":"high_privilege","summary":"An authenticated attacker can inject OS commands via the web interface to execute arbitrary code with root privileges on OptiLink GPON routers.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An OS command injection vulnerability exists in the OptiLink ONT1GEW GPON router firmware version V2.1.11_X101 Build 1127.190306 and earlier.
