Published: 09 April 2024
Summary
CVE-2024-26215 is a high-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Microsoft Windows Server 2008. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 8.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2024-26215 is a denial of service vulnerability affecting the DHCP Server Service on Windows systems. It is tracked under CWE-400 for uncontrolled resource consumption and is rated 7.5 on CVSS 3.1, reflecting network attack vector, low complexity, and no requirements for privileges or user interaction to impact availability.
An unauthenticated remote attacker can send crafted network traffic to an exposed DHCP server, triggering the flaw to exhaust resources and render the service unavailable. This can disrupt IP address assignment and related network operations for clients relying on the affected server.
Microsoft security advisories at the referenced MSRC pages indicate that patches addressing the issue are available and should be applied according to standard update guidance for DHCP servers.
The associated EPSS score has remained flat at 0.0758 with no material rise after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.
Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.
Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.
Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.
Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.
Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.
The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.
Timely maintenance support and spare parts enable rapid recovery from failures induced by uncontrolled resource consumption, shortening the impact window of denial-of-service attacks.
