CVE-2026-116235

Summary

A CRLF injection vulnerability exists in the L2TP authentication component of Oray Pugongying X5 Pro v7.6.1, where unsanitized user input in the Username field allows an attacker to inject carriage return and line feed characters, potentially enabling authentication bypass or log manipulation.

Exploitability

Exploitation requires high-privilege access (PR:H) and remote network access; no public exploit is confirmed, but the vulnerability has been published.

Blast radius

Successful exploitation could lead to unauthorized access, data exfiltration, or system compromise due to the high confidentiality, integrity, and availability impact (C:H/I:H/A:H).

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to a patched version of Oray Pugongying X5 Pro if one is available; otherwise, disable the L2TP authentication feature or restrict access to the endpoint until a fix is deployed.
