PingID Windows Login: Improper Privilege Management
CVE-2022-23720 is a high-severity improper privilege management vulnerability in PingID Windows Login from Ping Identity, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited with local access to the system by an attacker with administrator privileges, without any action from a user. The record lists version 2.8 as the first without the flaw, so updating PingID Windows Login to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update PingID Windows Login to 2.8 or a later version.
- Update Pingid Integration For Windows Login to 2.8 or a later version.

Official description
PingID Windows Login prior to 2.8 does not alert or halt operation if it has been provisioned with the full permissions PingID properties file. An IT administrator could mistakenly deploy administrator privileged PingID API credentials, such as those typically used by PingFederate, into PingID Windows Login user endpoints. Using sensitive full permissions properties file outside of a privileged trust boundary leads to an increased risk of exposure or discovery, and an attacker could leverage these credentials to perform administrative actions against PingID APIs or endpoints.

The underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
