SAP Internet Communication Framework Detection Scanner

The SAP Internet Communication Framework is a component of SAP systems that facilitates communication and data exchange over the internet between SAP applications and external entities. It is widely used by organizations implementing SAP software to ensure seamless integration and connectivity of their business processes with external applications. The framework supports a variety of communication protocols and provides secure communication channels for data exchange. SAP applications utilizing this framework are prevalent in industries such as finance, manufacturing, and services where real-time data integration is essential for efficient business operations. The framework is predominantly utilized by IT professionals and SAP administrators to manage and maintain communication channels within and outside their enterprise environments.

The vulnerability detected pertains to an information disclosure scenario where specific error messages within the SAP Internet Communication Framework can be exposed to unauthorized users. This condition arises when erroneous logon attempts result in visible error messages, returning a 404 HTTP status code, which can inadvertently reveal technical details about the SAP environment. Such information disclosure can be considered low-impact but may aid attackers in further reconnaissance activities. It is classified as a detection vulnerability because it involves identifying the presence of specific conditions that expose the framework to potential information leaks. The detection provides valuable insights into the system's handling of error messages.

Technically, the vulnerability involves an endpoint within the SAP Internet Communication Framework that responds with explicit logon error messages. The vulnerable parameter is related to logon attempts, where incorrect credentials or unauthorized access attempts may trigger these error messages. The core issue lies in how the framework communicates error states, particularly through the HTTP 404 status response, which should generally indicate a non-existent resource. This behavior could be tested by crafting HTTP requests to SAP endpoints and checking if the expected error messages are returned. By matching specific strings associated with SAP error messages and the 404 status, the vulnerability scanner can confirm their presence.

If exploited, this vulnerability may lead to the inadvertent disclosure of specific details about the SAP system, potentially aiding attackers in conducting further targeted attacks. Although considered a low-severity issue, the information gleaned from such messages can assist in identifying the software version, configuration details, or underlying infrastructure, posing an indirect threat. In a broader attack scenario, it might contribute to crafting tailored exploits against the SAP environment. Therefore, mitigating such information leaks is crucial for maintaining the security and integrity of SAP systems against reconnaissance activities.
