PingID integration for Windows login prior to 2.9 does not handle duplicate usernames, which can lead to a username collision when two people with the same username are provisioned onto the same machine at different times.

PingID Windows Login prior to 2.8 does not properly set permissions on the Windows Registry entries used to store sensitive API keys under some circumstances.

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.

PingID Windows Login prior to 2.8 does not authenticate communication with a local Java service used to capture security key requests. An attacker with the ability to execute code on the target machine maybe able to exploit and spoof the local Java service using multiple attack vectors. A successful attack can lead to code executed as SYSTEM by the PingID Windows Login application, or even a denial of service for offline security key authentication.

PingID Windows Login prior to 2.8 uses known vulnerable components that can lead to remote code execution. An attacker capable of achieving a sophisticated man-in-the-middle position, or to compromise Ping Identity web servers, could deliver malicious code that would be executed as SYSTEM by the PingID Windows Login application.

PingID Windows Login prior to 2.8 is vulnerable to a denial of service condition on local machines when combined with using offline security keys as part of authentication.

Use of static encryption key material allows forging an authentication token to other users within a tenant organization. MFA may be bypassed by redirecting an authentication flow to a target user. To exploit the vulnerability, must have compromised user credentials.

A misconfiguration of RSA in PingID Windows Login prior to 2.7 is vulnerable to pre-computed dictionary attacks, leading to an offline MFA bypass.

PingID Integration for Windows Login before 2.4.2 allows local users to gain privileges by modifying CefSharp.BrowserSubprocess.exe.
