{"id":"CVE-2026-116236","kind":"vulnerability","aliases":["CVE-2026-116236"],"related":[],"title":"Oray Pugongying X5 Pro: PPPoE setup flaw allows remote unrestricted file upload","description":"A vulnerability has been found in Oray Pugongying X5 Pro 7.6.1. Affected by this issue is the function plugin_init of the file /tmp/upload_files of the component PPPoE WAN Setting Handler. Such manipulation of the argument pppd_options leads to unrestricted upload. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.","summary":"The PPPoE WAN setting handler in the Oray Pugongying X5 Pro 7.6.1 fails to restrict the pppd_options argument in plugin_init, allowing unrestricted file upload. A remote attacker can likely place files on the device, and a public exploit exists.","severity":"high","cvss":8.3,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["infrastructure","network-appliance","oray","pppoe","pugongying-x5-pro"],"not_affected_if":["other-firmware-versions"],"how_to_check":"- unknown","fix":"- unknown","status":"open","published_at":"2026-10-26T09:16:35+00:00","first_seen_at":"2026-10-26T09:29:15+00:00","triaged_at":"2026-10-26T09:30:48+00:00","updated_at":"2026-10-26T09:30:48+00:00","category":"infrastructure","confidence":0.6,"triage":{"at":"2026-10-26T09:30:48Z","model":"claude-haiku-5-5","output":{"fix":"- unknown","reach":"internet","title":"Oray Pugongying X5 Pro: PPPoE setup flaw allows remote unrestricted file upload","impact":"high","summary":"The PPPoE WAN setting handler in the Oray Pugongying X5 Pro 7.6.1 fails to restrict the pppd_options argument in plugin_init, allowing unrestricted file upload.
