Security Bulletin: IBM DataPower Gateway potentially vulnerable to HTTP request smuggling

2 years ago

## Summary

These flaws have the potential to affect the API Gateway Sservice. IBM has addressed the CVEs

## Vulnerability Details

** CVEID: **[CVE-2022-32213]()
** DESCRIPTION: **Node.js is vulnerable to HTTP request smuggling, caused by the failure to correctly parse and validate Transfer-Encoding headers by the llhttp parser in the http module. A remote attacker could send a specially-crafted request to lead to HTTP Request Smuggling (HRS). An attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/230657]() for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

** CVEID: **[CVE-2022-32214]()
** DESCRIPTION: **Node.js is vulnerable to HTTP request smuggling, caused by the failure to strictly use the CRLF sequence to delimit HTTP requests by the llhttp parser in the http module. A remote attacker could send a specially-crafted request to lead to HTTP Request Smuggling (HRS). An attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/230658]() for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

** CVEID: **[CVE-2022-32215]()
** DESCRIPTION: **Node.js is vulnerable to HTTP request smuggling, caused by the failure to correctly handle multi-line Transfer-Encoding headers by the llhttp parser in the http module. A remote attacker could send a specially-crafted request to lead to HTTP Request Smuggling (HRS). An attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/230659]() 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.
