CVE-2019-0220: Apache HTTP Server

Medium severity, CVSS 5.3. EPSS: 18% chance of exploitation in the next 30 days.

A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them.
