A flaw exists in the Windows login flow where an AuthContext token can be exploited for replay attacks and authentication bypass.

A token is created using the username, current date/time, and a fixed AES-128 encryption key, which is the same across all installations.

Philips ISCV application prior to version 2.3.0 has an insufficient session expiration vulnerability where an attacker could reuse the session of a previously logged in user. This vulnerability exists when using ISCV together with an Electronic Medical Record (EMR) system, where ISCV is in KIOSK mode for multiple users and using Windows authentication. This may allow an attacker to gain unauthorized access to patient health information and potentially modify this information.

In Philips' IntelliSpace Cardiovascular (ISCV) products (ISCV Version 2.x or prior and Xcelera Version 4.1 or prior), an attacker with escalated privileges could access folders which contain executables where authenticated users have write permissions, and could then execute arbitrary code with local administrative permissions.

In Philips' IntelliSpace Cardiovascular (ISCV) products (ISCV Version 3.1 or prior and Xcelera Version 4.1 or prior), an unquoted search path or element vulnerability has been identified, which may allow an attacker to execute arbitrary code and escalate their level of privileges.

The workstation logging function in Philips IntelliSpace Cardiovascular (ISCV) 2.3.0 and earlier and Xcelera R4.1L1 and earlier records domain authentication credentials, which if accessed allows an attacker to use credentials to access the application, or other user entitlements.
