Calix GigaSpire Web Management utilities_configurationsave.cgi denial of service

Description

A flaw has been found in Calix GigaSpire 26.1.0. Impacted is an unknown function of the file utilities_configurationsave.cgi of the component Web Management Interface. Executing a manipulation of the argument sessionKey can lead to denial of service. The attack can be launched remotely. The exploit has been published and may be used. The existence of this vulnerability is still disputed at present. The vendor explains: "We reproduced the reported request pattern. The observed delay results from expected input-timeout handling while the handler waits for input data. We did not observe a backend crash, resource exhaustion, service instability, or loss of EWI availability, and the interface remained accessible during and after testing."
