CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2023-5676
DESCRIPTION: Eclipse OpenJ9 is vulnerable to a denial of service, caused by a flaw when a shutdown signal (SIGTERM, SIGINT or SIGHUP) is received before the JVM has finished initializing. By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause an infinite busy hang on a spinlock or a segmentation fault.
CVSS Base score: 4.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/271615 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2023-45857
DESCRIPTION: Axios is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input. By inserting the X-XSRF-TOKEN header using the secret XSRF-TOKEN cookie value in all requests to any server when the XSRF-TOKEN0 cookie is available, and the withCredentials setting is turned on, an attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.
CVSS Base score: 7.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/270574 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N)
CVEID: CVE-2023-41900
DESCRIPTION: Eclipse Jetty could allow a remote authenticated attacker to bypass security restrictions, caused by improper authentication validation when using the optional nested LoginService. By sending a specially crafted request, an attacker could exploit this vulnerability to bypass access restrictions.
CVSS Base score: 3.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/266185 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N)
CVEID: CVE-2023-40167
DESCRIPTION: Jetty is vulnerable to HTTP request smuggling, caused by improper parsing of the HTTP/1 request header. By sending a specially crafted request, a remote 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/266353 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-2023-36479
DESCRIPTION: Eclipse Jetty could provide weaker than expected security, caused by an errant command quoting flaw in the org.eclipse.jetty.servlets.CGI Servlet. A remote authenticated attacker could exploit this vulnerability to launch further attacks on the system.

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.
