Known exploited

CISA added this to the Known Exploited Vulnerabilities Catalog on 18 Aug 2022. US federal agencies had to remediate by 8 Sept 2022, a deadline that has passed.

Required action. Apply updates per vendor instructions.

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.
