High

Base vector

AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L

Name of the Vulnerable Software and Affected Versions: Wcms version 0.3.2

Description: The issue allows an attacker to send crafted requests from the back-end server of a vulnerable web application via the pagename parameter to "wex/html.php". This can be used to identify open ports, local network hosts, and execute commands on local services.

Recommendations: For Wcms version 0.3.2, consider restricting access to the "wex/html.php" endpoint and limiting the use of the pagename parameter until a fix is available. As a temporary workaround, restrict the functionality that allows sending crafted requests from the back-end server to minimize the risk of exploitation.
