A remote unauthenticated attacker can chain a directory traversal (which helps to bypass authentication) with an insecure file upload to achieve Remote Code Execution as SYSTEM.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 12.8%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
