Akamai Guardicore Platform Agent vulnerabilities

A use-after-free vulnerability in the Windows WFP callout driver of Akamai Guardicore Platform Agent (GPA) allows a local low-privileged user to cause a denial of service (system crash / BSOD) via an outbound ICMPv6 packet containing an IPv6 Hop-by-Hop extension header. When the IPv6 ICMP redirect policy is active, the packet is copied into a buffer that is freed but subsequently passed to a downstream filter. The size of the freed allocation is attacker-controlled, enabling kernel pool grooming.

An integer underflow exists in the DNS proxy component of the macOS NetworkExtension system extension shipped with Akamai Guardicore Platform Agent (GPA) for macOS, whereby if a UDP datagram shorter than 96 bytes that begins with a specific value is received, a subsequent size computation underflows to a near-SIZE_MAX value, causing an allocation failure and uncaught Objective-C exception that aborts the root system extension.

A use-after-free exists in the Windows WFP packet-capture driver shipped with Akamai Guardicore Platform Agent (GPA) before 7.4. When an IPv6 proxy/redirect rule is active, a local attacker with Administrator privileges can send a single crafted outbound IPv6 packet via a raw IPV6_HDRINCL socket to trigger this at DISPATCH_LEVEL.

Akamai Guardicore Platform Agent (GPA) before 7.4 for macOS is affected by a local privilege escalation vulnerability within the wapptunneld component. The vulnerability is caused by a lack of input validation when the service uses network interface names to execute system utilities, resulting in command injection. An unprivileged local user with permissions to modify network interface names can exploit this by renaming a network interface to include a malicious shell payload via System Settings. When the "Log out from your IdP" action is subsequently triggered, the wapptunneld service processes the poisoned interface name, leading to the execution of arbitrary commands with root privileges.
