A vulnerability in the react-editable-json-tree library allows for arbitrary code execution due to improper parsing and evaluation of functions within the JSON data.

Understanding CVE-2022-36010

This CVE describes a critical security issue in the react-editable-json-tree library that could lead to arbitrary code execution.

What is CVE-2022-36010?

The CVE highlights a flaw in the library where strings are parsed as functions using the

eval

function, potentially allowing malicious code execution when displaying data from untrusted sources.

The Impact of CVE-2022-36010

The vulnerability poses a critical threat as it enables attackers to execute arbitrary code within the application, compromising data integrity and confidentiality.

Technical Details of CVE-2022-36010

The vulnerability description, affected systems and versions, and the exploitation mechanism are outlined below.

Vulnerability Description

The issue arises from the use of

eval

to execute strings as functions, enabling the execution of arbitrary code within the JSON structure being displayed.

Affected Systems and Versions

Versions prior to 2.2.2 of the react-editable-json-tree library are affected by this vulnerability.

Exploitation Mechanism

Attackers can exploit this vulnerability by injecting malicious code within the JSON data, leading to arbitrary code execution.

Mitigation and Prevention

To address CVE-2022-36010, immediate steps, long-term security practices, and patching recommendations are crucial.

Immediate Steps to Take

Users on version

<2.2.2

should upgrade to the latest version promptly.
Users on version

^2.2.2

must explicitly set

JsonTree

's

allowFunctionEvaluation

prop to

false

.

Long-Term Security Practices

Adopting secure coding practices and ensuring data sanitization when handling user-generated content are essential for long-term security.

Patching and Updates

For versions

>=3.0.0

,

allowFunctionEvaluation

is already set to

false

by default, eliminating the need for further action.
