TITLE:
Huawei HG510 Security Bypass and Cross-Site Request Forgery
Vulnerabilities

SECUNIA ADVISORY ID:
SA38591

VERIFY ADVISORY:
http://secunia.com/advisories/38591/

DESCRIPTION:
Ivan Markovic has reported some vulnerabilities in Huawei HG510,
which can be exploited by malicious people to bypass certain security
restrictions and conduct cross-site request forgery attacks.

1) The device allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. reboot the device or change
certain settings (including passwords).

2) The device does not properly restrict access to the rebootinfo.cgi
script. This can be exploited to reboot the device by accessing the
script directly.

Note: This can also be exploited via cross-site request forgery
attacks (see vulnerability #1).

SOLUTION:
Restrict access to the device. Do not browse untrusted websites or
follow untrusted links while logged in to the device.

PROVIDED AND/OR DISCOVERED BY:
Ivan Markovic, Network Security Solutions
