**Name of the Vulnerable Software and Affected Versions** Primavera P6 Enterprise Project Portfolio Management versions 20.12.1.0 through 20.12.21.5 Primavera P6 Enterprise Project Portfolio Management versions 21.12.1.0 through 21.12.20.0 Primavera P6 Enterprise Project Portfolio Management version 22.12.1.0 **Description** The issue is related to improper authorization in the Web Access component of Primavera P6 Enterprise Project Portfolio Management. It allows a low-privileged attacker with network access via HTTP to compromise the system. Successful attacks require human interaction from a person other than the attacker and may significantly impact additional products. This can result in unauthorized update, insert, or delete access to some accessible data, as well as unauthorized read access to a subset of accessible data. **Recommendations** For versions 20.12.1.0 through 20.12.21.5, update to a version that includes the fix for this issue. For versions 21.12.1.0 through 21.12.20.0, update to a version that includes the fix for this issue. For version 22.12.1.0, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the Web Access component until a patch is available.
