Security Bulletin
Summary
IBM has addressed several CVEs which may affect the APIC Gateway Service
Vulnerability Details
CVEID: CVE-2021-44532
DESCRIPTION: Node.js could allow a remote attacker to bypass security restrictions, caused by a string injection vulnerability when name constraints were used within a certificate chain. An attacker could exploit this vulnerability to bypass the name constraints.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216931 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2021-22960
DESCRIPTION: Node.js is vulnerable to HTTP request smuggling, caused by an error when parsing the body of chunked requests. 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/211171 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-2021-44533
DESCRIPTION: Node.js could allow a remote attacker to bypass security restrictions, caused by the incorrect handling of multi-value Relative Distinguished Names. By crafting certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name, an attacker could exploit this vulnerability to bypass the certificate subject verification.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216932 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2021-22959
DESCRIPTION: Node.js is vulnerable to HTTP request smuggling, caused by an error related to a space in headers. A remote attacker could send a specially-crafted request with a space (SP) right after the header name before the colon 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/211168 for the current score.
