Description:
farhad koosha has reported a vulnerability in ACS Blog, which can be exploited by malicious people to bypass certain security restrictions.
The problem is that the "inc_login_check.asp" script insecurely determines if an administrator has been authenticated based on a certain cookie value. This can be exploited to bypass the authentication process by sending a specially crafted cookie.
The vulnerability has been reported in version 0.8, 1.0, 1.0.1, 1.0.2, 1.0.3, 1.1, 1.1.2 and 1.1.3. Other versions may also be affected.
Solution:
Edit the source code to ensure that users are properly authenticated.
