Improper Authorization check in SAP Cloud Connector

SAP Cloud Connector contains an improper authorization check, which could be exploited by a low-privileged attacker through specially crafted requests. Exploitation requires the attacker to be on an adjacent network. Successful exploitation could allow the attacker to obtain limited information about internal systems, resulting in low impact on confidentiality. There is no impact on integrity and availability.

Missing authorization check in SAP Cloud Connector

Due to a missing authorization check in SAP Cloud Connector, an attacker on an adjacent network with low privileges could send a crafted request to the endpoint responsible for testing LDAP connections. A successful exploit could lead to reduced performance, hence a low-impact on availability of the service. Confidentiality and integrity of the data are not affected.

Improper Certificate Validation in SAP Cloud Connector

Due to improper validation of certificate in SAP Cloud Connector - version 2.0, attacker can impersonate the genuine servers to interact with SCC breaking the mutual authentication. Hence, the attacker can intercept the request to view/modify sensitive information. There is no impact on the availability of the system.

Denial of service (DOS) in SAP Cloud Connector

SAP Cloud Connector - version 2.0, allows an authenticated user with low privilege to perform Denial of service attack from adjacent UI by sending a malicious request which leads to low impact on the availability and no impact on confidentiality or Integrity  of the application.

Potentially, SAP Cloud Connector, version - 2.0 communication with the backend is accepted without sufficient validation of the certificate.

SAP Cloud Connector, version - 2.0, does not sufficiently encode user-controlled inputs, allowing an attacker with Administrator rights, to include malicious codes that get stored in the database, and when accessed, could be executed in the application, resulting in Stored Cross-Site Scripting.

SAP Cloud Connector, version - 2.0, allows an authenticated administrator to modify a configuration file to inject malicious codes that could potentially lead to OS command execution.

SAP Cloud Connector, version - 2.0, allows the upload of zip files as backup. This backup file can be tricked to inject special elements such as '..' and '/' separators, for attackers to escape outside of the restricted location to access files or directories.

SAP Cloud Connector, before version 2.11.3, allows an attacker to inject code that can be executed by the application. An attacker could thereby control the behavior of the application.

SAP Cloud Connector, before version 2.11.3, does not perform any authentication checks for functionalities that require user identity.
