Summary
A vulnerability exists in the RTU500 web server component that can cause a denial of service to the RTU500 CMU application if a specially crafted message sequence is executed on a WebSocket connection.
An attacker must be properly authenticated and the test mode function of RTU500 must be enabled to exploit this vulnerability.
The affected CMU will automatically recover itself if an attacker successfully exploits this vulnerability.

Title
PAN-OS: Firewall Denial of Service (DoS) Using Specially Crafted Traffic
Summary
A null pointer dereference in Palo Alto Networks PAN-OS software on PA-800 Series, PA-3200 Series, PA-5200 Series, and PA-7000 Series hardware platforms when Decryption policy is enabled allows an unauthenticated attacker to crash PAN-OS by sending specific traffic through the data plane, resulting in a denial of service (DoS) condition. Repeated attempts to trigger this condition will result in PAN-OS entering maintenance mode.
Palo Alto Networks VM-Series, Cloud NGFW, and Prisma Access are not affected.
This issue only affects PA-800 Series, PA-3200 Series, PA-5200 Series, and PA-7000 Series running these specific versions of PAN-OS:
* 10.2.7-h12
* 10.2.8-h10
* 10.2.9-h9
* 10.2.9-h11
* 10.2.10-h2
* 10.2.10-h3
* 10.2.11
* 10.2.11-h1
* 10.2.11-h2
* 10.2.11-h3
* 11.1.2-h9
* 11.1.2-h12
* 11.1.3-h2

Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Requirements
Select a programming language that is not susceptible to these issues.
Mitigation
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
