CVE-2014-0117
The mod_proxy module in the Apache HTTP Server 2.4.x before 2.4.10, when a reverse proxy is enabled, allows remote attackers to cause a denial of service (child-process crash) via a crafted HTTP Connection header.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 35.5%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.
