CVE-2024-21537: Arbitrary Code Execution in lilconfig
Versions of the package lilconfig from 3.1.0 and before 3.1.1 are vulnerable to Arbitrary Code Execution due to the insecure usage of eval in the dynamicImport function. An attacker can exploit this vulnerability by passing a malicious input through the defaultLoaders function.
AI Analysis
Technical Summary
CVE-2024-21537 affects the lilconfig package, specifically versions 3.1.0 and earlier up to but not including 3.1.1. The vulnerability is due to the unsafe use of eval in the dynamicImport function. An attacker can exploit this by providing crafted input to the defaultLoaders function, leading to arbitrary code execution. The CVSS 4.0 score is 9.3, indicating a critical severity with network attack vector, low complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code on affected systems without requiring privileges or user interaction. This can lead to full compromise of the system running the vulnerable lilconfig version.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid using vulnerable versions or restrict input to the defaultLoaders function to trusted sources only.
