Synopsis

The remote web server is affected by multiple vulnerabilities.

Description

The version of IBM HTTP Server running on the remote host is affected by multiple vulnerabilities related to Apache HTTP Server, as follows:

- 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. (CVE-2019-0220)

- In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected. (CVE-2019-0211)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to IBM HTTP Server version 8.5.5.16, 9.0.5.0, or later. Alternatively, upgrade to the minimal fix pack levels required by the interim fix and then apply Interim Fix PH09869.
