Security Bulletin
Summary
IBM Cloud Pak for Network Automation 2.6.3 fixes multiple security vulnerabilities, listed in the CVEs below.
Vulnerability Details
CVEID: CVE-2023-35887
DESCRIPTION: Apache MINA SSHD could allow a remote authenticated attacker to obtain sensitive information, caused by improper authorization validation by the RootedFilesystem. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain information about items outside the rooted tree, and use this information to launch further attacks against the affected system.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/259974 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2023-26115
DESCRIPTION: Node.js word-wrap module is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw in the result variable. By sending a specially crafted regex input, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/256901 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-2021-33621
DESCRIPTION: RubyGems cgi gem is vulnerable to HTTP response splitting attacks. A remote authenticated attacker could exploit this vulnerability to inject arbitrary HTTP/1.1 response header in some form and cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting, and possibly obtain sensitive information.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/240690 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2023-27522
DESCRIPTION: Apache HTTP Server is vulnerable to HTTP request smuggling, caused by improper parsing of the HTTP transfer-encoding request header by the mod_proxy_uwsgi module. By sending a specially-crafted HTTP(S) transfer-encoding request header, 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/249442 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-2023-26364
DESCRIPTION: Node.js @adobe/css-tools module is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw. By providing specially crafted regex input using a CSS file, a remote authenticated attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/265366 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L)
CVEID: CVE-2023-34462
DESCRIPTION: Netty is vulnerable to a denial of service, caused by a flaw with allocating up to 16MB of heap for each channel during the TLS handshake the SniHandler class. By sending a specially crafted client hello packet, a remote authenticated attacker could exploit this vulnerability to cause a OutOfMemoryError and so result in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258713 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2023-26136
DESCRIPTION: Salesforce tough-cookie could allow a remote attacker to execute arbitrary code on the system, caused by a prototype pollution flaw due to improper handling of Cookies when using CookieJar in rejectPublicSuffixes=false mode. By adding or modifying properties of Object.prototype using a __proto__ or constructor payload, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/259555 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-2023-38408
DESCRIPTION: OpenSSH could allow a remote attacker to execute arbitrary code on the system, caused by a flaw in the forwarded ssh-agent. By sending specially crafted requests, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/261022 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2023-3899
DESCRIPTION: Red Hat Enterprise Linux could allow a local authenticated attacker to gain elevated privileges on the system, caused by improper authorization by the subscription-manager. By sending a specially crafted request through D-Bus interface com.redhat.RHSM1, an authenticated attacker could exploit this vulnerability to gain elevated privileges to an unconfined root.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/264328 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.
