CVE-2022-22536
SAP Multiple Products HTTP Request Smuggling Vulnerability
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 8 September 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.
Description
SAP NetWeaver Application Server ABAP, SAP NetWeaver Application Server Java, ABAP Platform, SAP Content Server 7.53 and SAP Web Dispatcher are vulnerable for request smuggling and request concatenation. An unauthenticated attacker can prepend a victim's request with arbitrary data. This way, the attacker can execute functions impersonating the victim or poison intermediary Web caches. A successful attack could result in complete compromise of Confidentiality, Integrity and Availability of the system.
