CVE-2022-3517 : Vulnerability Insights and Analysis

A vulnerability was found in the minimatch package that allows a Regular Expression Denial of Service (ReDoS) attack, resulting in Denial of Service.

Understanding CVE-2022-3517

This CVE involves a flaw in the minimatch package that can be exploited to cause a Denial of Service (DoS) through Regular Expression Denial of Service (ReDoS) attack vectors.

What is CVE-2022-3517?

CVE-2022-3517 is a vulnerability in minimatch versions prior to 3.0.5 that allows attackers to trigger a ReDoS attack by calling the braceExpand function with specific arguments. This can lead to service disruption and impact the availability of the system.

The Impact of CVE-2022-3517

The impact of this vulnerability is the potential for a successful DoS attack, causing service unavailability and disrupting regular operations. It could be exploited by threat actors to target systems using affected versions of the minimatch package.

Technical Details of CVE-2022-3517

This section covers the specifics of the vulnerability, including affected systems, exploitation mechanism, and more.

Vulnerability Description

The vulnerability in minimatch allows for a ReDoS attack via the braceExpand function, resulting in DoS conditions due to inefficient Regular Expression evaluation.

Affected Systems and Versions

The affected product is minimatch, specifically versions prior to 3.0.5. Systems that have not been updated to the patched version are at risk of exploitation.

Exploitation Mechanism

Attackers can exploit this vulnerability by providing specific inputs to the braceExpand function within affected versions of minimatch, triggering the ReDoS attack and causing service disruption.
