Security Bulletin


Summary

IBM Resilient SOAR is Using Components with Known Vulnerabilities - Eclipse Jetty.

Vulnerability Details

CVEID:   CVE-2021-28163
DESCRIPTION:   Eclipse Jetty could allow a remote authenticated attacker to obtain sensitive information, caused by a flaw when the ${jetty.base} directory or the ${jetty.base}/webapps directory is a symlink. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain webapp directory contents information, and use this information to launch further attacks against the affected system.
CVSS Base score: 2.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/199303 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N)

CVEID:   CVE-2021-28164
DESCRIPTION:   Eclipse Jetty could allow a remote attacker to obtain sensitive information, caused by improper input validation by the default compliance mode. By sending specially-crafted requests with URIs contain %2e or %2e%2e segments, an attacker could exploit this vulnerability to access protected resources within the WEB-INF directory, 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/199304 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-2021-28165
DESCRIPTION:   Eclipse Jetty is vulnerable to a denial of service, caused by improper input valistion. By sending a specially-crafted TLS frame, a remote attacker could exploit this vulnerability to cause CPU resources to reach to 100% usage.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/199305 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)
