Technical details
This is an authorization bypass vulnerability in the Shopping Cart component of Oracle iStore that allows low-privileged attackers to access restricted data. The vulnerability is exploitable over HTTP with network access and does not require user interaction. An attacker with low privileges can escalate access to view critical data or complete datasets accessible by iStore, and the scope of impact extends beyond iStore to other connected E-Business Suite components. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N) indicates the vulnerability is easily exploitable with low attack complexity and has high confidentiality impact.
