var-202109-1802
Vulnerability from variot
A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. This vulnerability allows remote attackers to initiate arbitrary server-side requests on affected installations of Hewlett Packard Enterprise OneView. Authentication is not required to exploit this vulnerability.The specific flaw exists within the REST service, which listens on TCP port 443 by default. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. The server is fast, reliable and extensible through a simple API. The vulnerability stems from the mod_proxy module failing to properly validate user input. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

- Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied. 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. Refer to the Release Notes for information on the security fix included in this release. Solution:
Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on.
The References section of this erratum contains a download link for the update. You must be logged in to download the update. ========================================================================== Ubuntu Security Notice USN-5090-4 September 28, 2021
apache2 regression
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 ESM
Summary:
USN-5090-1 introduced a regression in Apache HTTP Server. One of the upstream fixes introduced a regression in UDS URIs. This update fixes the problem.
Original advisory details:
James Kettle discovered that the Apache HTTP Server HTTP/2 module incorrectly handled certain crafted methods. A remote attacker could possibly use this issue to perform request splitting or cache poisoning attacks. (CVE-2021-34798)
Li Zhi Xin discovered that the Apache mod_proxy_uwsgi module incorrectly handled certain request uri-paths. This issue only affected Ubuntu 20.04 LTS and Ubuntu 21.04. If the server was configured with third-party modules, a remote attacker could use this issue to cause the server to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2021-39275)
It was discovered that the Apache mod_proxy module incorrectly handled certain request uri-paths. (CVE-2021-40438)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 ESM: apache2 2.4.18-2ubuntu3.17+esm3 apache2-bin 2.4.18-2ubuntu3.17+esm3
In general, a standard system update will make all the necessary changes

"data": "A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. This vulnerability allows remote attackers to initiate arbitrary server-side requests on affected installations of Hewlett Packard Enterprise OneView. Authentication is not required to exploit this vulnerability.The specific flaw exists within the REST service, which listens on TCP port 443 by default. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. The server is fast, reliable and extensible through a simple API. The vulnerability stems from the mod_proxy module failing to properly validate user input. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA256\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Important: httpd security update\nAdvisory ID: RHSA-2021:3856-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://access.redhat.com/errata/RHSA-2021:3856\nIssue date: 2021-10-14\nCVE Names: CVE-2021-40438 \n=====================================================================\n\n1.

Solution:\n\nBefore applying this update, make sure all previously released errata\nrelevant to your system have been applied. This software, such as Apache HTTP Server, is\ncommon to multiple JBoss middleware products, and is packaged under Red Hat\nJBoss Core Services to allow for faster distribution of updates, and for a\nmore consistent update experience. Refer to the Release Notes for information on the security fix\nincluded in this release. Solution:\n\nBefore applying the update, back up your existing installation, including\nall applications, configuration files, databases and database settings, and\nso on. \n\nThe References section of this erratum contains a download link for the\nupdate. You must be logged in to download the update. ==========================================================================\nUbuntu Security Notice USN-5090-4\nSeptember 28, 2021\n\napache2 regression\n==========================================================================\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 16.04 ESM\n\nSummary:\n\nUSN-5090-1 introduced a regression in Apache HTTP Server. One of the upstream\nfixes introduced a regression in UDS URIs. This update fixes the problem. \n\nOriginal advisory details:\n\n James Kettle discovered that the Apache HTTP Server HTTP/2 module\n incorrectly handled certain crafted methods. A remote attacker could\n possibly use this issue to perform request splitting or cache poisoning\n attacks. \n (CVE-2021-34798)\n \n Li Zhi Xin discovered that the Apache mod_proxy_uwsgi module incorrectly\n handled certain request uri-paths. \n This issue only affected Ubuntu 20.04 LTS and Ubuntu 21.04. If the server was configured with third-party modules, a remote\n attacker could use this issue to cause the server to crash, resulting in a\n denial of service, or possibly execute arbitrary code. (CVE-2021-39275)\n \n It was discovered that the Apache mod_proxy module incorrectly handled\n certain request uri-paths. \n (CVE-2021-40438)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 16.04 ESM:\n apache2 2.4.18-2ubuntu3.17+esm3\n apache2-bin 2.4.18-2ubuntu3.17+esm3\n\nIn general, a standard system update will make all the necessary changes",
