Security Bulletin: IBM Integration Bus is vulnerable to multiple CVEs due to Apache Tomcat.

Summary

Due to Apache Tomcat, IBM Integration Bus is vulnerable to multiple CVEs. (CVE-2023-45648, CVE-2023-42794, CVE-2023-44487, CVE-2023-42795).

Vulnerability Details

CVEID:CVE-2023-45648
**DESCRIPTION:**Apache Tomcat is vulnerable to HTTP request smuggling, caused by improper parsing of HTTP trailer headers. By sending a specially crafted invalid trailer header, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268200 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-2023-42794
**DESCRIPTION:**Apache Tomcat is vulnerable to a denial of service, caused by accumulation of temporary files on Windows when a web application opened a stream for an uploaded file but failed to close the stream. A remote attacker could exploit this vulnerability to cause a denial of service due to the disk being full.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268202 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-44487
**DESCRIPTION:**Multiple vendors are vulnerable to a denial of service, caused by a flaw in handling multiplexed streams in the HTTP/2 protocol. By sending numerous HTTP/2 requests and RST_STREAM frames over multiple streams, a remote attacker could exploit this vulnerability to cause a denial of service due to server resource consumption.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268044 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-42795
**DESCRIPTION:**Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by an incomplete Cleanup vulnerability when recycling various internal objects. By skipping some parts of the recycling process, an attacker could exploit this vulnerability to obtain sensitive information leaking from the current request/response to the next.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268201 for the current score.
