Description

SAP Approuter does not consistently enforce integrity verification on certain session-related request headers under specific conditions. An attacker with low privileges could send a specially crafted request that bypasses the integrity check and loads another user's session context. Successful exploitation requires the attacker to have previously observed matching session values out-of-band, which makes the attack complex to execute. This could result in a high impact on confidentiality and a low impact on integrity. There is no impact on availability.
