PHP uses longjmp() for out-of-memory (OOM) errors to exit the current context and abort handling of the request. Some contexts may not properly account for this scenario and leave request memory in an uninitialized state before performing an allocation. The subsequent request cleanup procedure may read or branch on this memory. Multiple OOM strategies can consistently trigger this condition and lead to remote code execution (RCE).
PHP has various global state that temporarily points into request memory. In some scenarios, global state may not be correctly reset, or may be repopulated after being reset. The global state may then refer to request memory even after it has been freed. Subsequent requests may read or branch on this stale state before it is fully initialized. Multiple strategies can trigger this condition and produce remote code execution (RCE).
A remote code execution (RCE) vulnerability in the management interface of Palo Alto Networks PAN-OS® software enables an authenticated attacker with network access to execute arbitrary code with root privileges on the firewall.
The security risk posed by this issue is minimized by restricting access to the management interface to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 .
This issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series).
Cloud NGFW and Prisma® Access are not impacted by this vulnerability.
A command injection vulnerability in the management plane of Palo Alto Networks PAN-OS® software enables an authenticated administrator to execute arbitrary OS commands as root.
The security risk posed by this issue is significantly minimized when CLI access is restricted to a limited group of administrators.
This issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series).
Cloud NGFW and Prisma Access® are not impacted by this vulnerability.
Multiple denial of service vulnerabilities in Palo Alto Networks PAN-OS® software allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition by sending specially crafted network traffic to or through a dataplane interface. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.
Panorama is not impacted by these vulnerabilities.
An XML injection vulnerability in the Large Scale VPN (LSVPN) functionality of Palo Alto Networks PAN-OS® software enables an unauthenticated attacker with network access to inject malicious XML content, potentially leading to information disclosure or corruption of internal LSVPN satellite data.
Panorama, Cloud NGFW, and Prisma® Access are not impacted by this vulnerability.
A server-side request forgery (SSRF) vulnerability in Palo Alto Networks PAN-OS software enables an authenticated administrator with network access to the management web interface to make unauthorized requests from the firewall to internal services.
The security risk posed by this issue is minimized when the management interface is restricted to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 .
Panorama, Cloud NGFW, and Prisma® Access are not impacted by this vulnerability.
A file deletion vulnerability in Palo Alto Networks PAN-OS® software enables an unauthenticated attacker with network access to the management web interface to delete files from a temporary directory.
The security risk posed by this issue is minimized by restricting access to the management web interface to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 .
This issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series).
Cloud NGFW and Prisma® Access are not impacted by this vulnerability.
An authentication bypass vulnerability in Large Scale VPN ( LSVPN) functionality of Palo Alto Networks PAN-OS software allows an attacker with network access to bypass security restrictions and establish an unauthorized site-to-site VPN connection.
Panorama, Cloud NGFW, and Prisma® Access are not impacted by this vulnerability.
An IPv6 packet processing vulnerability in the dataplane of Palo Alto Networks PAN-OS® software enables an unauthenticated attacker to bypass firewall security policy enforcement, allowing network traffic that should be blocked to reach protected services.
Cloud NGFW and Panorama are not impacted by this vulnerability.
