    Title
    Calix GigaSpire Web Management utilities_configurationsave.cgi denial of service
    Summary
    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."

    Title
    Calix GigaSpire traceroute.cmd denial of service
    Summary
    A vulnerability has been found in Calix GigaSpire 26.1.0. The affected element is an unknown function of the file traceroute.cmd. The manipulation leads to denial of service. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The presence of this vulnerability remains uncertain at this time. The vendor explains: "After reviewing the researcher's videos, we repeated the test using his described setup: the traceroute cancel request was sent while a second client was connected to the EWI. The second client remained connected and was not interrupted, and we did not observe a forced logout, session invalidation, or loss of EWI availability."

    Title
    Calix GigaSpire Web Management utilities_configurationsave.cgi denial of service
    Summary
    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."

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.\""
