AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A flaw was found in Undertow. Servlets using a method that calls HttpServletRequestImpl.getParameterNames() can cause an OutOfMemoryError when the client sends a request with large parameter names. This issue can be exploited by an unauthorized user to cause a remote denial-of-service (DoS) attack.

The vulnerability CVE-2024-4027 affects Undertow, a web server component used in Red Hat OpenShift Serverless. It arises from improper input validation when servlets invoke HttpServletRequestImpl.getParameterNames(). Specifically, if a client sends a request containing very large parameter names, the server may run out of memory, causing an OutOfMemoryError and resulting in a denial-of-service condition. The flaw can be exploited remotely without authentication. Red Hat has rated this issue as having an important impact due to the potential for remote DoS attacks. No mitigation is currently available, and users are advised to apply updates when they become available. The CVSS v3.1 base score is 7.5 (high severity) with network attack vector, low complexity, no privileges or user interaction required, and an impact limited to availability.
