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.

Mitigating Controls

Likely Mitigating Controls AI

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.

addresses: CWE-400

Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.

addresses: CWE-400

Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.

addresses: CWE-400

Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.

addresses: CWE-400

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.

addresses: CWE-400

Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.

addresses: CWE-400

Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.

addresses: CWE-400

The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.

addresses: CWE-400

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.
