Technical Analysis
CVE-2024-20767 highlights a vulnerability in a ColdFusion application, specifically within a server management component (/CFIDE/adminapi/_servermanager/servermanager.cfc
). This component, intended for managing server operations, can be manipulated to execute unauthorized actions due to improper security checks on user access levels.
The vulnerability arises because the application fails to adequately verify the permissions of certain classes, allowing a class with a specific access level (identified as “3”) to bypass security measures. Attackers can exploit this oversight by dissecting the application’s files to target the getHeartBeat
class, which is not properly secured. Once access is gained, attackers can call internal methods that should be restricted, leading to unauthorized actions such as reading sensitive files or downloading data dumps from the server.
This issue is particularly concerning because it allows attackers to use a unique identifier (UUID) generated by the application to fake authorization, gaining access to a servlet (PMSGenericServlet
) meant for privileged operations. The exploitation of this servlet could lead to further unauthorized activities, such as reading or altering files on the server, by manipulating parameters like the username and filename in requests.
