Security Bulletin
Summary
Apache HTTP Server is used by IBM App Connect Enterprise Certified Container for Mapping Assistance. IBM App Connect Enterprise Certified Container DesignerAuthoring operands that use Mapping Assistance may be vulnerable to denial of service due to CVE-2022-29404 and CVE-2022-30522, loss of confidentiality due to CVE-2022-30556 and security restrictions bypassing due to CVE-2022-31813. This bulletin provides patch information to address the reported vulnerabilities CVE-2022-29404, CVE-2022-30522, CVE-2022-30556 and CVE-2022-31813 in Apache HTTP Server.
Vulnerability Details
CVEID: CVE-2022-29404
DESCRIPTION: Apache HTTP Server is vulnerable to a denial of service, caused by no default limit on possible input size. By sending a specially crafted request to a lua script that calls r:parsebody(0), an attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228339 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2022-30522
DESCRIPTION: Apache HTTP Server is vulnerable to a denial of service when configured to do transformations with mod_sed in contexts where the input to mod_sed may be very large. By making excessively large memory allocations, a remote attacker could exploit this vulnerability to trigger an abort.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228338 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2022-30556
DESCRIPTION: Apache HTTP Server could allow a remote attacker to obtain sensitive information, caused by an error in mod_lua with websockets. An attacker could exploit this vulnerability to return lengths to applications calling r:wsread() that point past the end of the storage allocated for the buffer.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228336 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2022-31813
DESCRIPTION: Apache HTTP Server could allow a remote attacker to bypass security restrictions, caused by the failure to send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. An attacker could exploit this vulnerability to bypass IP based authentication on the origin server/application.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228337 for the current score.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
