Technical Analysis

CVE-2022-37623 is a critical prototype pollution vulnerability identified in the function resolveShims within the resolve-shims.js file of the thlorenz browserify-shim package, version 3.8.15. Prototype pollution is a type of security flaw that allows an attacker to manipulate the prototype of a base object in JavaScript, potentially leading to arbitrary code execution, denial of service, or data corruption. In this case, the vulnerability arises through the shimPath variable in resolve-shims.js, which is improperly handled, allowing an attacker to inject or modify properties on the Object prototype. This can lead to widespread impact because many JavaScript applications rely on the integrity of object prototypes for their logic and security. The vulnerability has a CVSS v3.1 base score of 9.8, indicating it is critical, with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, meaning it is remotely exploitable over the network without any privileges or user interaction, and it affects confidentiality, integrity, and availability at a high level. No specific affected product or vendor beyond the package name is listed, but browserify-shim is a popular tool used in JavaScript development to shim or polyfill modules for browser compatibility. While no known exploits in the wild have been reported, the severity and ease of exploitation make it a significant threat. The CWE-1321 classification corresponds to prototype pollution, emphasizing the nature of the vulnerability. The lack of patch links suggests that remediation may require updating or replacing the vulnerable package or applying custom fixes. Organizations using browserify-shim 3.8.15 or dependent projects should consider this vulnerability critical and act accordingly.

Potential Impact

For European organizations, the impact of CVE-2022-37623 can be substantial, especially those involved in web development, software supply chain, or running JavaScript-based applications that incorporate the vulnerable browserify-shim package. Exploitation could lead to unauthorized data access, manipulation of application logic, or service disruption, affecting business continuity and data privacy compliance obligations such as GDPR. Since the vulnerability allows remote exploitation without authentication or user interaction, attackers could leverage it to compromise internal applications or public-facing services. This could result in data breaches, loss of customer trust, regulatory penalties, and operational downtime. The widespread use of JavaScript tooling in European tech ecosystems means that many organizations could be indirectly affected through dependencies. Additionally, sectors with high reliance on web applications, such as finance, healthcare, and e-commerce, face elevated risks. The vulnerability could also be exploited as a pivot point for further attacks within a network, increasing the overall threat landscape for European enterprises.

Mitigation Recommendations

To mitigate CVE-2022-37623 effectively, European organizations should: 1) Identify all instances of the browserify-shim package version 3.8.15 or earlier in their software supply chain, including transitive dependencies in JavaScript projects. 2) Update to a patched version of browserify-shim if available; if no official patch exists, consider replacing the package with a secure alternative or applying custom code fixes to sanitize the shimPath input and prevent prototype pollution. 3) Implement strict input validation and sanitization in applications consuming this package to reduce the risk of malicious input exploitation. 4) Employ runtime application self-protection (RASP) or Web Application Firewalls (WAF) with rules targeting prototype pollution attack patterns to detect and block exploitation attempts. 5) Conduct thorough code reviews and static analysis focusing on prototype pollution risks in JavaScript codebases. 6) Monitor security advisories and threat intelligence feeds for updates or emerging exploit techniques related to this vulnerability. 7) Educate development teams about the risks of prototype pollution and secure coding practices to prevent similar vulnerabilities in the future.
