CVE-2019-0220: Medium severity Apache HTTP Server vulnerability

Published Apr 1, 2019
·
Updated

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.

  26. Compensating control

    Update Apache HTTP Server 2.4.0–2.4.38 mitigations by adjusting directives that match the request URL path (e.g., LocationMatch and RewriteRule) to use regular expressions that account for duplicate multiple consecutive slashes ('/'), since Apache processing will implicitly collapse consecutive slashes but regex matches must handle them explicitly.
