Summary

CVE-2024-51557 is a high-severity Improper Control of Interaction Frequency (CWE-799) vulnerability in 63Moons Aero. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 38th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-10 (Concurrent Session Control) and AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

Directly enforces a hard limit on concurrent sessions, structurally preventing unbounded resource allocation.

ac-7 directly enforces a limit on the frequency of invalid authentication attempts, structurally preventing the weakness for that interaction class.

Requires explicit allocation of resources by priority or quota, directly stopping unlimited allocation.

sc-5 reduces the impact of excessive request volume (DoS) but does not itself impose the frequency controls whose absence defines the weakness.

Monitoring capacity and taking action to maintain availability directly reduces unchecked resource allocation.

Protecting networks from unauthorized usage can incorporate rate limiting to bound interaction frequency.

finds

Baseline comparison of CPU, memory and bandwidth usage helps surface uncontrolled resource allocations before they cause service degradation.

prevents

Capacity projections and elasticity measures ensure that allocation requests are bounded and can be throttled, reducing the window in which an attacker can force unbounded resource reservations.

mitigates

Defining retention periods and deletion schedules for backup copies prevents indefinite accumulation of data on storage media without corresponding resource-management controls.

mitigates

Architectural redundancy and automatic failover limit the impact of an attacker who forces excessive allocations, because spare capacity can absorb the load until the primary instance recovers.

mitigates

Network security controls can enforce rate limiting and throttling at the perimeter.

prevents

Application security requirements explicitly include controls on interaction frequency and throttling.
