| Title | Oray Pgyer X5 Pro Router 7.6.1 Improper Neutralization of CRLF Sequences ('CRLF Injection') |
|---|
| Description | Oray Pgyer X5 Pro Router firmware 7.6.1 accepts quotes and line breaks in an L2TP username supplied by a caller with the management system password. The router writes that username into a pppd options file, where it can add a plugin directive naming a shared library uploaded through the same authenticated interface. When a reachable L2TP server answers the router's call, pppd loads the library and runs plugin_init as root before PPP account authentication. |
