CVE-2021-40350

Status: ModifiedCritical (9.8)—

webctrl.cgi.elf on Christie Digital DWU850-GS V06.46 devices allows attackers to perform any desired action via a crafted query containing an unspecified Cookie header. Authentication bypass can be achieved by including an administrative cookie that the device does not validate.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
