WebCube: Origin Validation Error
CVE-2022-23764 is a critical-severity origin validation error vulnerability in WebCube from TERUTEN, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.2.0.0 as the first without the flaw, so updating WebCube to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.68% chance of exploitation within 30 days, higher than 53% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update WebCube to 1.2.0.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
