CVE-2022-44784 Information

Description

An issue was discovered in Appalti & Contratti 9.12.2. The target web applications LFS and DL229 expose a set of services provided by the Axis 1.4 instance embedded directly into the applications as hinted by the WEB-INF/web.xml file leaked through Local File Inclusion. Among the exposed services there is the Axis AdminService which through the default configuration should normally be accessible only by the localhost. Nevertheless by trying to access the mentioned service both in LFS and DL229 the service can actually be reached even by remote users allowing creation of arbitrary services on the server side. When an attacker can reach the AdminService they can use it to instantiate arbitrary services on the server. The exploit procedure is well known and described in Generic AXIS-SSRF exploitation. Basically the attack consists of writing a JSP page inside the root directory of the web application through the org.apache.axis.handlers.LogHandler class.
