CVE-2022-37599 describes a Regular Expression Denial of Service (ReDoS) vulnerability found in the Function interpolateName within interpolateName.js in webpack loader-utils 2.0.0. This flaw can be triggered via the resourcePath variable, potentially leading to significant impact on application availability.
With a CVSS score of 7.5, this vulnerability is classified as high severity, indicating a serious risk. The exploitability is rated high, and the attack vector is network-based, making it easily accessible to remote adversaries. Organizations should implement immediate measures to address this vulnerability.
Risk to organizations includes potential service disruptions due to denial of service attacks. Attackers may leverage this vulnerability to exhaust resources, resulting in degraded performance or complete downtime.
Given the high severity and impact on availability, organizations should prioritize patching immediately. Upgrading to the latest version of webpack.js loader-utils is essential to mitigate this risk.
Vulnerability Details
A Regular expression denial of service (ReDoS) flaw was found in Function interpolateName in interpolateName.js in webpack loader-utils 2.0.0 via the resourcePath variable in interpolateName.js.
The CVSS score for this vulnerability is 7.5, which is classified as high severity. This indicates a significant risk to applications using affected versions. The vulnerability affects webpack.js loader-utils versions from 1.0.0 up to, but not including, 1.4.2; and from 2.0.0 up to, but not including, 2.0.4; as well as from 3.0.0 up to, but not including, 3.2.1.
The CWE classification for this vulnerability is CWE-1333.
Technical Analysis
The root cause of CVE-2022-37599 lies in the improper handling of regular expressions within the interpolateName function. This flaw allows attackers to craft specific input that can cause the regular expression engine to enter catastrophic backtracking, leading to denial of service.
The attack vector is network-based, meaning that an attacker can exploit the vulnerability remotely without needing physical access to the system. The attack complexity is low, requiring no special privileges or user interaction, making it an attractive target for attackers.
The availability impact is rated as high, indicating that successful exploitation could lead to significant downtime or unavailability of services. There is no confidentiality or integrity impact associated with this vulnerability.
Risk & Impact Analysis
The real-world risk of CVE-2022-37599 is significant, particularly for organizations that rely on webpack.js loader-utils for their applications. The potential for denial of service attacks poses a threat to application availability, which can impact customer satisfaction and business operations.
Organizations should assess their exposure to this vulnerability based on their deployment of affected versions. The blast radius could be extensive, as the vulnerability can be exploited remotely and may affect multiple services relying on the same component.
Given the CVSS score of 7.5, organizations should address this vulnerability in their priority patch cycle. Failure to do so may result in service disruptions that could lead to financial losses and reputational damage.
