Analysis

AI-generated

Technical impact

Based on the description, it is inferred that the vulnerability resides in the PPPoE WAN Setting Handler on Oray Pugongying X5 Pro 7.6.1. During plugin initialization, a user‑controlled argument named pppd_options is accepted and used to write files to the /tmp/upload_files directory without proper validation. This unrestricted upload allows an attacker to place arbitrary files on the router, potentially leading to remote code execution if the uploaded content is executed. The weakness corresponds to CWE‑284 (Improper Access Control) and CWE‑434 (Unrestricted Upload of File with Dangerous Type).

Affected Systems

Oray Pugongying X5 Pro, firmware version 7.6.1. No other product or version information is available.

Risk and Exploitability

Based on the description, it is inferred that the CVSS score of 8.6 indicates medium‑to‑high severity. EPSS data is not available, but the vulnerability has been publicly disclosed and can be exploited remotely via the PPPoE WAN Setting interface. Because the exploit can be launched from any network connected to the router and does not require local privilege escalation, the probability of exploitation is significant. The vendor has not yet released a patch, and the vulnerability is not listed in CISA’s KEV catalog.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the vendor’s official firmware update once it is available.
  • Disable or remove the PPPoE WAN Setting Handler to eliminate the upload pathway.
  • Restrict access to the router’s administrative interface to trusted networks only by configuring firewall rules or the router’s ACL settings.
