Summary

Brocade Fabric OS versions before 10.0.1 are affected. Unauthenticated HTTP endpoints in the web management daemon process URL query parameters without checking array index boundaries or numeric ranges, which causes an out-of-bounds memory read (CWE-125). An unauthenticated remote attacker can send a single crafted HTTP request to crash the web management process, causing denial of service and temporary management-plane disruption.

Description from the CNA

An out-of-bounds memory read vulnerability exists in the web management daemon of Brocade Fabric OS versions before 10.0.1. Unauthenticated HTTP endpoints process specific URL query parameters without validating array index boundaries or performing numerical range checks. An unauthenticated remote attacker can exploit this issue by sending a single, crafted HTTP request containing extreme numerical values in the query string. This causes an invalid memory dereference, resulting in a crash of the web management process (Denial of Service) and potential temporary management-plane disruption.
