A set of recently patched SAP vulnerabilities has been surfaced by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), with their recommendation to patch as soon as possible. Discovered and disclosed by security researchers at Onapsis, these three vulnerabilities are referred to as ICMAD and affect SAP applications which utilize the SAP Internet Communication Manager (ICM).

Which SAP NetWeaver versions are affected?

Some versions of SAP NetWeaver contain all three of these ICMAD vulnerabilities:

  • CVE-2022-22536 (CVSS “critical” score of 10.0) - vulnerable to request smuggling and request concatenation, successful exploitation by an unauthenticated attacker resulting in code execution, victim impersonation, data exfiltration, denial of service, and more. In addition to NetWeaver, some versions of SAP Web Dispatcher and SAP Content Server also contain this vulnerability.
  • CVE-2022-22532 (CVSS “high” score of 8.1) - vulnerability in shared memory handling, successful exploitation by an unauthenticated attacker resulting in code execution, victim impersonation, or taking over the victim’s logon session.
  • CVE-2022-22533 (CVSS “low” score of 3.7) - vulnerability in error handling which could result in a denial of service attack by exhausting available memory, leading to system shutdown.

Is a security patch available?

Yes. SAP made patched software available earlier this week. While there currently are no known customer breaches related to exploitation of the ICMAD vulnerabilities, SAP does strongly recommend that admins update to the latest available versions as soon as possible.
