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

========================================================================== Ubuntu Security Notice USN-5090-3 September 28, 2021
apache2 regression
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.04
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
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 21.04: apache2 2.4.46-4ubuntu1.3 apache2-bin 2.4.46-4ubuntu1.3
Ubuntu 20.04 LTS: apache2 2.4.41-4ubuntu3.6 apache2-bin 2.4.41-4ubuntu3.6
Ubuntu 18.04 LTS: apache2 2.4.29-1ubuntu4.18 apache2-bin 2.4.29-1ubuntu4.18
In general, a standard system update will make all the necessary changes. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202208-20

"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.

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 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 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 21.04:\n apache2 2.4.46-4ubuntu1.3\n apache2-bin 2.4.46-4ubuntu1.3\n\nUbuntu 20.04 LTS:\n apache2 2.4.41-4ubuntu3.6\n apache2-bin 2.4.41-4ubuntu3.6\n\nUbuntu 18.04 LTS:\n apache2 2.4.29-1ubuntu4.18\n apache2-bin 2.4.29-1ubuntu4.18\n\nIn general, a standard system update will make all the necessary changes. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nGentoo Linux Security Advisory GLSA 202208-20\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n https://security.gentoo.org/\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\n Severity: High\n Title: Apache HTTPD: Multiple Vulnerabilities\n Date: August 14, 2022\n Bugs: #813429, #816399, #816864, #829722, #835131, #850622\n ID: 202208-20\n\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\nSynopsis\n=======\nMultiple vulnerabilities have been discovered in Apache Webserver, the\nworst of which could result in remote code execution.
