Memory safety vulnerability in NetScaler ADC and Gateway
CVE-2024-8534
What is CVE-2024-8534?
CVE-2024-8534 is a memory safety vulnerability identified in the NetScaler ADC and Gateway solutions, which are used to optimize application delivery and enhance secure remote access. This vulnerability could potentially allow for memory corruption, resulting in a Denial of Service (DoS) condition if specific configurations are not properly managed. Organizations utilizing these products, particularly in scenarios where the appliance is configured as a Gateway with the RDP feature enabled or set up as an Auth Server, may face significant operational disruptions and security risks resulting from this flaw.
Technical Details
The vulnerability arises from improper handling of memory within the NetScaler ADC and Gateway products when configured in specific ways. For instance, it can be triggered if the appliance is set as a Gateway (VPN Vserver) with the RDP feature enabled, or if an RDP Proxy Server Profile is created in conjunction with the Gateway configuration. Memory corruption stemming from this vulnerability can lead to unpredictable behavior of the affected systems, potentially exposing them to further security threats or failures.
Impact of the Vulnerability
-
Service Disruption: The primary impact of CVE-2024-8534 is the potential for Denial of Service, where affected systems become unresponsive, thereby hindering access to critical applications and services for end-users.
-
Memory Corruption: This vulnerability allows for memory corruption, which can lead to erratic behavior in applications running on the affected system, increasing the risk of system crashes or data losses.
-
Security Posture Risk: Organizations leveraging NetScaler for enhancing security and application delivery may inadvertently compromise their security posture, as the vulnerability could be exploited to manipulate traffic or access sensitive information if combined with other attack vectors.
