CVE-2016-5696 Kernel Vulnerability
A vulnerability exists in the kernel of PAN-OS that may result in Information Disclosure. The challenge ACK rate limiting in the kernel's networking subsystem may allow an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the changes by probing packets. (ref # PAN-62500 / CVE-2016-5696).
Successful exploitation of this issue may allow an attacker to terminate a TCP connection or inject a payload into non-secured TCP connection between two endpoints on the network.
This issue affects PAN-OS 6.1, PAN-OS 7.0.15 and earlier, PAN-OS 7.1.9 and earlier
|PAN-OS 7.1||<= 7.1.9||>= 7.1.10|
|PAN-OS 7.0||<= 7.0.15||>= 7.0.16|
CVSSv3.1 Base Score: 4.8 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L)
PAN-OS 7.0.16 and later, PAN-OS 7.1.10 and later
