Denial of service in Calix GigaSpire 26.1.0 is reachable remotely through manipulation of the traceroute.cmd diagnostic endpoint, causing availability disruption to the affected device. The root cause is improper resource handling (CWE-404) within the traceroute function, which fails to properly release resources under adversarial input. A proof-of-concept exploit has been publicly disclosed; no vendor patch or advisory is available as the vendor did not respond to coordinated disclosure.
Denial of service in Calix GigaSpire 26.1.0 is achievable remotely by low-privileged attackers who manipulate the sessionKey argument within the utilities_configurationsave.cgi endpoint of the Web Management Interface, causing improper resource release (CWE-404) and disrupting device availability.
