Rule Document 1:66504

Rule Category

SERVER-WEBAPP -- Snort has detected traffic exploiting vulnerabilities in web based applications on servers.

Alert Message

SERVER-WEBAPP OSGeo GeoServer XML external entity injection attempt

Rule Explanation

This rule looks for XML payloads containing external entity declarations in HTTP requests to the "/geoserver/wfs" endpoint with the "GetMap" operation. Successful exploitation could allow an attacker to read arbitrary files or cause denial of service on the server.

What To Look For

This rule fires on attempts to exploit an XML external entity injection (XXE) vulnerability in OSGeo GeoServer web applications.

Adversaries may attempt to take advantage of a weakness in an Internet-facing computer or program using software, data, or commands in order to cause unintended or unanticipated behavior. The weakness in the system can be a bug, a glitch, or a design vulnerability. These applications are often websites, but can include databases (like SQL), standard services (like SMB or SSH), network device administration and management protocols (like SNMP and Smart Install), and any other applications with Internet accessible open sockets, such as web servers and related services.

Rule Vulnerability

Insecure Deserialization

Insecure Deserialization relates to web application security. Applications turn an object into data through serialization; the reverse of that process, deserialization, can be vulnerable to attacks when the application trusts the data that is being deserialized. Serialized data is machine readable and not encrypted; serialized user-supplied data should not be trusted. Deserialization attacks can lead to remote code execution.
