gSOAP Local File Inclusion Scanner

gSOAP is a software development toolkit that provides tools for developing XML web services and SOAP protocols. It is widely used by developers for its efficiency in processing SOAP messages and ease of integration into C/C++ applications. Often used in embedded devices and systems, gSOAP allows developers to create secure and interoperable web services. The software is employed by businesses that require efficient communication protocols for their applications in sectors such as telecommunications, industrial automation, and consumer electronics.

The Local File Inclusion (LFI) vulnerability allows an attacker to trick a system into executing files from a local system path. This particular vulnerability occurs when user input is improperly sanitized, enabling the inclusion of local files within an application. Attackers exploit this by manipulating paths, often utilizing directory traversal techniques to access sensitive files outside the intended directory.

In gSOAP, the vulnerability typically manifests in SOAP endpoints that accept file paths as parameters, such as in file upload or configuration retrieval functions. The vulnerable parameter might be a file name or path passed within the SOAP envelope, which is then used without proper validation to read or include files from the server's filesystem.

If exploited, an attacker can read arbitrary files on the server, including configuration files, source code, or sensitive data like passwords and database credentials. This can lead to further compromise of the system, such as privilege escalation or data exfiltration, potentially impacting the entire infrastructure relying on gSOAP services.
