CVE-2024-0801 Scanner

Arcserve Unified Data Protection (UDP) is a comprehensive data protection solution used by enterprises to secure their critical data across diverse IT environments. Many organizations rely on it for its robust backup and recovery capabilities, high availability, and ease of data management. The software is typically deployed in medium to large enterprises with complex data infrastructures. It facilitates data protection for physical, virtual, and cloud systems from a single management interface. Arcserve UDP is particularly renowned for its capability to deliver fast, efficient recovery in disaster scenarios. Its extensive support for various platforms and scalable architecture makes it a trusted choice for data protection.

The vulnerability identified in Arcserve UDP involves a Denial of Service (DoS) flaw in the ASNative.dll component. DoS vulnerabilities can lead to the shutdown or extreme slow down of service operations, rendering systems unreachable. This particular vulnerability can be exploited by remote attackers to trigger a service interruption, potentially crashing systems or making them extremely sluggish. The concern with Denial of Service vulnerabilities is that they can dramatically affect business operations by making critical services unavailable. Such disruptions, especially in data protection services, can lead to data recovery failures during crucial times. The impact is heightened in environments where service continuity is paramount.

Technically, this Denial of Service vulnerability within Arcserve UDP is exploited through HTTP POST requests sent to the EdgeServiceConsoleImpl service. It involves sending carefully crafted requests that result in an error or abnormal system behavior. Attackers can specifically exploit XML SOAP requests, targeting specific endpoints and parameters to provoke the DoS condition. The template observes HTTP responses with error status codes, like 500, 502, and 503, which indicate service disruptions or unavailability. These requests can lead to critical service unavailability symptoms such as proxy errors or service headers returning with server crash indications.

Exploiting this vulnerability can have serious repercussions, including halting business-critical operations due to data inaccessibility. It can lead to loss of productivity and affect overall business performance, especially for enterprises relying heavily on the IT infrastructure Arcserve UDP protects. Moreover, prolonged downtime might lead to cascading effects, such as increased operational costs and negative impact on customer relations. Unaddressed, attackers might continue to exploit this doorway, posing continuous threats and pressures on resources needed to resolve system downtimes.
