The Onapsis Research Labs and SAP Product Security Response Team (PSRT) collaborated to discover and patch three critical vulnerabilities that affected Internet Communication Manager (ICM), a core component of SAP business applications. This discovery will require immediate attention by most SAP customers given the widespread usage of the vulnerable technology component in SAP landscapes around the world.
The individual ICMAD vulnerabilities are identified as CVE-2022-22536, CVE-2022-22532, and CVE-2022-22533 — the first of which received the highest possible risk score, a 10 out of 10, while the other two received scores of 8.1 and 7.5, respectively. As a result, the U.S. Department of Homeland Security’s CISA has issued a Current Activity Alert.
Both SAP and Onapsis advise impacted organizations to prioritize applying the Security Notes 3123396 and 3123427 to their affected SAP applications immediately. If exploited, these vulnerabilities, dubbed ICMAD (Internet Communication Manager Advanced Desync), enable attackers to execute serious malicious activities on SAP users, business information, and processes — and ultimately compromise unpatched SAP applications.
What Are the ICMAD SAP Vulnerabilities?
The ICMAD vulnerabilities are particularly critical because the issues exist by default in the SAP Internet Communication Manager (ICM). The ICM is one of the most important components of an SAP NetWeaver application server: It is present in most SAP products and is a critical part of the overall SAP technology stack, connecting SAP applications with the Internet.
Malicious actors can easily leverage the most critical vulnerability (CVSSv3 10.0) in unprotected systems; the exploit is simple, requires no previous authentication, no preconditions are necessary, and the payload can be sent through HTTP(S), the most widely used network service to access SAP applications.
