The web management console in Trend Micro OfficeScan 7.0 through 8.0, Worry-Free Business Security 5.0, and Client/Server/Messaging Suite 3.5 and 3.6 creates a random session token based only on the login time, which makes it easier for remote attackers to hijack sessions via brute-force attacks. NOTE: this can be leveraged for code execution through an unspecified "manipulation of the configuration."

TP-Link TL-WA850RE Wi-Fi Range Extender before v6_200923 was discovered to use highly predictable and easily detectable session keys, allowing attackers to gain administrative privileges.

A flaw was found in all versions of the Keycloak operator, before version 8.0.2,(community only) where the operator generates a random admin password when installing Keycloak, however the password remains the same when deployed to the same OpenShift namespace.

A CWE-330 - Use of Insufficiently Random Values vulnerability exists in Smartlink, PowerTag, and Wiser Series Gateways (see security notification for version information) that could allow unauthorized users to login.

In Silicon Labs uC/TCP-IP 3.6.0, TCP ISNs are improperly random.

Prima Systems FlexAir, Versions 2.3.38 and prior. The application generates database backup files with a predictable name, and an attacker can use brute force to identify the database backup file name. A malicious actor can exploit this issue to download the database file and disclose login information, which can allow the attacker to bypass authentication and have full access to the system.

reNgine through 0.5 relies on a predictable directory name.

An issue was discovered in the nanorand crate before 0.5.1 for Rust. It caused any random number generator (even ChaCha) to return all zeroes because integer truncation was mishandled.
