Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Requires timely remediation of the prototype pollution flaw in php-parser v3.2.1 through patching or replacement to prevent DoS exploitation.

prevent

Validates crafted payloads supplied to the lib.combine function to block prototype pollution attacks.

preventdetect

Implements protections against resource exhaustion DoS resulting from prototype pollution in php-parser.

MITRE ATT&CK Enterprise TechniquesAI

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 enables direct application-layer DoS via crafted input over the network (resource exhaustion/crash).

Confidence: MEDIUM · MITRE ATT&CK Enterprise v18.1

NVD Description

A prototype pollution in the lib.combine function of php-parser v3.2.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

Deeper analysisAI

CVE-2024-57071 is a prototype pollution vulnerability in the lib.combine function of php-parser version 3.2.1. This flaw allows attackers to supply a crafted payload that pollutes the JavaScript prototype chain, leading to a Denial of Service (DoS) condition. The vulnerability is classified under CWE-1321 (Prototype Pollution) and 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.

The attack requires no authentication or user interaction, making it exploitable by unauthenticated attackers over the network with low complexity. By sending a specially crafted payload to an application using the vulnerable php-parser v3.2.1 library, attackers can trigger the prototype pollution in lib.combine, resulting in resource exhaustion or application crashes that disrupt service availability without affecting confidentiality or integrity.
