Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Path traversal (CVE-ID: CVE-2018-19748)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

app/plug/attachment/controller/admincontroller.php in SDCMS 1.6 allows reading arbitrary files via a /?m=plug&c=admin&a=index&p=attachment&root= directory traversal. The value of the root parameter must be base64 encoded (note that base64 encoding, instead of URL encoding, is very rare in a directory traversal attack vector).


2) Code Injection (CVE-ID: CVE-2018-19520)

The vulnerability allows a remote authenticated user to execute arbitrary code.

An issue was discovered in SDCMS 1.6 with PHP 5.x. app/admin/controller/themecontroller.php uses a check_bad function in an attempt to block certain PHP functions such as eval, but does not prevent use of preg_replace 'e' calls, allowing users to execute arbitrary code by leveraging access to admin template management.
