SAP Approuter is vulnerable due to inconsistent enforcement of integrity verification on certain session-related request headers, allowing an attacker with low privileges to potentially access another user's session context. Although successful exploitation is complex and requires prior observation of session values, it poses a risk to confidentiality. Organizations using SAP Approuter should prioritize addressing this vulnerability to protect user session data.

Original NVD 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.
