Compass Security AG has reported two security issues in OKI C5510MFP, which can be exploited by malicious people to disclose sensitive information and to bypass certain security restrictions.

1) A security issue is caused due to the configuration of the printer being sent in clear text when connecting to TCP ports 5548 or 7777. This can be exploited to obtain the administration password by connecting to the affected ports.

2) The problem is that the password can be reset without authentication. This can be exploited to gain access to the configuration interface.

The security issues are reported in OKI C5510MFP (Printer CU Version: H2.15 / Printer PU Version: 01.03.01 / System F/W Version: 1.01 / Web Page Version: 1.00). Other versions may also be affected.
