Summary

CVE-2024-4068 is a high-severity Excessive Platform Resource Consumption within a Loop (CWE-1050) vulnerability in Jonschlinkert Braces. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Exhaustion Flood (T1499.001); ranked in the top 29% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SC-5 (Denial-of-service Protection) — see the control section below for these in your framework.

Vulnerability Data

The NPM package `braces`, versions prior to 3.0.3, fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. In `lib/parse.js,` if a malicious user sends "imbalanced braces" as input, the parsing will enter a…

loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 developer testing can discover loops that consume platform resources before deployment.

SC-5 directly limits the effects of resource-exhaustion events that constitute uncontrolled consumption.

SC-6 directly protects resource availability by enforcing allocation limits that bound consumption from faulty loops.

AC-10 caps concurrent sessions, reducing blast radius when a loop consumes session or connection resources.

Process isolation confines resource consumption to separate domains, reducing blast radius without stopping the root flaw.

finds

Monitoring can alert on resource abuse but does not eliminate the coding flaw.

finds

Security testing can discover the defect but does not remove it from production code.

prevents

By continuously monitoring utilization, stress-testing peak loads, and maintaining documented plans to scale or throttle resources, the control directly limits an attacker’s ability to drive a system into uncontrolled resource exhaustion.

finds

Pre-agreed severity-based prioritization and resource allocation during incident triage reduce the likelihood that an attacker-induced resource exhaustion will overwhelm the organization before corrective action is taken.

mitigates

Business-continuity plans that include resource-management controls reduce the likelihood that an attacker can trigger uncontrolled resource consumption by forcing the system into a degraded or fallback state.

mitigates

Defining RTOs and capacity requirements for ICT services during business-impact analysis forces organizations to provision sufficient resources and throttling mechanisms, reducing the likelihood that an attacker can induce denial-of-service through uncontrolled resource consumption.
