A denial-of-service vulnerability exists in CyberPower PowerPanel Business (PPB) 4.11.0. An unauthenticated remote attacker can restart the ppbd.exe process via the PowerPanel Business Service Watchdog service listening on TCP port 2003. The attacker can repeatedly restart ppbd.exe to render it unavailable.

CyberPower PowerPanel business application code contains a hard-coded set of authentication credentials. This could result in an attacker bypassing authentication and gaining administrator privileges.

CyberPower PowerPanel business application code contains a hard-coded JWT signing key. This could result in an attacker forging JWT tokens to bypass authentication.

A specially crafted Zip file containing path traversal characters can be imported to the CyberPower PowerPanel server, which allows file writing to the server outside the intended scope, and could allow an attacker to achieve remote code execution.

Hard-coded credentials are used by the  CyberPower PowerPanel platform to authenticate to the database, other services, and the cloud. This could result in an attacker gaining access to services with the privileges of a Powerpanel business application.

Hard-coded credentials for the CyberPower PowerPanel test server can be found in the production code. This might result in an attacker gaining access to the testing or production server.

The key used to encrypt passwords stored in the database can be found in the CyberPower PowerPanel application code, allowing the passwords to be recovered.

An attacker with certain MQTT permissions can create malicious messages to all CyberPower PowerPanel devices. This could result in an attacker injecting SQL syntax, writing arbitrary files to the system, and executing remote code.

The devices which CyberPower PowerPanel manages use identical certificates based on a hard-coded cryptographic key. This can allow an attacker to impersonate any client in the system and send malicious data.

Certain MQTT wildcards are not blocked on the CyberPower PowerPanel system, which might result in an attacker obtaining data from throughout the system after gaining access to any device.
