Security Bulletin: Multiple vulnerabilities affect IBM Db2® REST

Summary

IBM has released the below fix for IBM Db2® REST in response to multiple vulnerabilities found in multiple components. The vulnerabilities have been addressed.

Vulnerability Details

CVEID:CVE-2023-45283
**DESCRIPTION:**Golang Go could allow a remote attacker to traverse directories on the system, caused by the failure to recognize paths with a ??\ prefix as a Root Local Device path prefix in the filepath and safefilepath package. An attacker could send a specially crafted URL request containing “dot dot” sequences (/…/) to view arbitrary files on the system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/270990 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-2023-45284
**DESCRIPTION:**Golang Go could provide weaker than expected security, caused by the failure to correctly detect reserved device names in some cases by the IsLocal function in the filepath package. An attacker could exploit this vulnerability to report “COM1”, and reserved names “COM” and “LPT” followed by superscript 1, 2, or 3 as local.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/270989 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-2023-45285
**DESCRIPTION:**Golang Go could allow a remote attacker to obtain sensitive information, caused by a flaw when using go get to fetch a module with the “.git” suffix. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information from the insecure “git://” protocol, and use this information to launch further attacks against the affected system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/273323 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2023-39326
**DESCRIPTION:**Golang Go could allow a remote attacker to obtain sensitive information, caused by a flaw in the net/http package. By sending a specially crafted HTTP request, an attacker could exploit this vulnerability to read many more bytes from the network than are in the body, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/273322 for the current score.
