Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

SI-2 requires timely flaw remediation, directly addressing the prototype pollution vulnerability in expand-object v0.4.2 by patching or upgrading to a non-vulnerable version.

prevent

SC-5 implements denial-of-service protections such as resource limits and traffic filtering to block crafted payloads that trigger the DoS condition.

prevent

SI-10 enforces input validation to detect and reject specially crafted payloads targeting prototype pollution in the lib function.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Prototype pollution in public-facing JS package directly enables remote unauthenticated exploitation (T1190) leading to application-layer DoS via crafted input (T1499.004).

NVD Description

A prototype pollution in the lib function of expand-object v0.4.2 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

Deeper analysisAI

CVE-2024-57069 is a prototype pollution vulnerability in the lib function of the expand-object package version 0.4.2. This issue allows attackers to cause a Denial of Service (DoS) condition by supplying a crafted payload. The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity primarily due to its impact on availability, and is classified under CWE-1321.

The vulnerability can be exploited over the network by any unauthenticated attacker with low complexity and no need for user interaction. By providing a specially crafted payload to the affected lib function, the attacker can trigger a DoS, disrupting service availability without affecting confidentiality or integrity.
