CVE-2022-37264

Vulnerability

Overview

CVE-2022-37264 is a prototype pollution vulnerability in the steal module loader version 2.2.4. The issue resides in the main.js file, specifically in the handling of the optionName variable [1][4]. Prototype pollution occurs when an attacker can inject properties into an object's prototype, potentially affecting all objects of that type in the application.

Exploitation

An attacker can exploit this vulnerability by crafting input that manipulates the optionName variable, leading to the pollution of the Object.prototype. This can be achieved without authentication if the application processes user-controlled data through the affected code path [3]. The attack surface includes any application using steal 2.2.4 that accepts external configuration or options.

Impact

Successful exploitation allows an attacker to modify the behavior of all objects in the application, potentially leading to arbitrary code execution, denial of service, or data manipulation. The severity is high because prototype pollution can bypass security controls and affect the entire application runtime [1].

Mitigation

As of the publication date, no patch has been released for this vulnerability. Users are advised to upgrade to a newer version of steal if available, or to implement input validation and sanitization to prevent untrusted data from reaching the vulnerable code path [2]. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog.
