Operationally, ranked in the top 9.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Microsoft Message Queuing (MSMQ) contains a denial-of-service vulnerability identified as CVE-2024-49096. The flaw is characterized by CWE-400 and carries a CVSS 3.1 base score of 7.5, reflecting a network-vector attack that requires low complexity, no privileges, and no user interaction to produce a high impact on availability while leaving confidentiality and integrity unaffected.
An unauthenticated remote attacker can send specially crafted network traffic to an MSMQ instance and trigger the denial-of-service condition, rendering the queuing service unavailable. The attack requires no authentication or local access, making any exposed MSMQ endpoint reachable over the network a potential target.
EPSS probability for the CVE rose from a low baseline to a peak of 0.1673 on 2025-12-18 before receding to the current value of 0.0583, indicating that exploitation interest increased after public 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.
