Summary
Red Hat Security Advisory: Red Hat JBoss Core Services Apache HTTP Server 2.4.29 SP2 security update

Notes

Topic
Red Hat JBoss Core Services Pack Apache Server 2.4.29 Service Pack 2 zip release for RHEL 6 and RHEL 7 is available. Red Hat Product Security has rated this release as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat JBoss Core Services is a set of supplementary software for Red Hat JBoss middleware products. This software, such as Apache HTTP Server, is common to multiple JBoss middleware products, and is packaged under Red Hat JBoss Core Services to allow for faster distribution of updates, and for a more consistent update experience. This release adds the new Apache HTTP Server 2.4.29 Service Pack 2 packages that are part of the JBoss Core Services offering. It serves as a replacement for Red Hat JBoss Core Services Apache HTTP Server 2.4.29 SP1, and includes bug fixes and enhancements. Refer to the Release Notes for information on the most significant bug fixes, enhancements and component upgrades included in this release. Security Fix(es): * openssl: Malicious server can send large prime to client during DH(E) TLS handshake causing the client to hang (CVE-2018-0732) * openssl: ROHNP - Key Extraction Side Channel in Multiple Crypto Libraries (CVE-2018-0495) * httpd: privilege escalation from modules scripts (CVE-2019-0211) Details around this issue, including information about the CVE, severity of the issue, and CVSS scores can be found on the CVE pages listed in the References section below.

Due to the nature of the flaw, the uploaded script would not run as a restricted privileged user, but rather it runs as root allowing for privilege escalation from the restricted user to root on the web server.  \n\nDepending on the configuration of the server, you would need local (AV:L) privileges to place the script or network (AV:N) privileges if the server ran an application that permitted uploading scripts directly.  The latter scenario is not common for unauthenticated users.  Once the attacker can place the script somewhere in the web root where it can be easily exploited (AC:L).  This type of setup is more common in shared hosted environments (PR:L) and would allow an attacker with access to a site on the shared hosted to impact the confidentiality, integrity, and availability (CIA:H) with no interaction (UI:N).  Due to the elevated privileges obtained, there is an impact to the system beyond the web server itself (S:C).",
