SAP NetWeaver Application Server ABAP Access Control

Session hijacking in SAP NetWeaver Application Server for ABAP and ABAP Platform allows an unauthenticated remote attacker to assume another authenticated user's session by exploiting an integer underflow that causes a previously buffered request to be reprocessed in the wrong connection context. The attack is constrained by a narrow race-condition timing window requiring a victim session to be in a buffered state simultaneously, limiting mass exploitation but not targeted attacks against high-value SAP landscapes. Successful exploitation yields high confidentiality and integrity impact consistent with full session takeover; no public exploit code or active exploitation has been identified at time of analysis.

Unauthorized configuration data disclosure in SAP NetWeaver and ABAP Platform allows authenticated network attackers to read sensitive system configuration and security-relevant settings without holding the required authorization. The flaw stems from a missing authorization check (CWE-862) in the Application Server ABAP component, meaning any low-privileged authenticated user can query configuration details that should be restricted to privileged roles. Impact is confined to confidentiality at a low level; no public exploit or CISA KEV listing has been identified at time of analysis.
