Summary
Apache Tomcat, Open SSL, and Apache Tomcat have multiple security
vulnerabilities that could allow a remote attacker to exploit the Rational
Build Forge application. Respective security vulnerabilities are discussed in
detail in the subsequent sections.
Vulnerability Details
This section includes the vulnerability details that affects the Rational Build
Forge.
CVE-ID: CVE-2018-8014
DESCRIPTION: Apache Tomcat could provide weaker than expected security, caused
by insecure default settings for the CORS filter. A remote attacker could
exploit this vulnerability to launch further attacks on the system.
CVSS Base Score: 5.3
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
143411 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVE-ID: CVE-2018-8034
DESCRIPTION: Apache Tomcat could allow a remote attacker to bypass security
restrictions, caused by a missing host name verification when using TLS with
the WebSocket client. An attacker could exploit this vulnerability to bypass
security constraints to access restricted resources.
CVSS Base Score: 3.7
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
147211 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVE-ID: CVE-2018-0732
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
sending of a very large prime value to the client by a malicious server during
key agreement in a TLS handshake. By spending an unreasonably long period of
time generating a key for this prime, a remote attacker could exploit this
vulnerability to cause the client to hang.
CVSS Base Score: 3.7
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
144658 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVE-ID: CVE-2018-0737
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by a cache-timing side channel attack in the RSA Key
generation algorithm. An attacker with access to mount cache timing attacks
during the RSA key generation process could exploit this vulnerability to
recover the private key and obtain sensitive information.
CVSS Base Score: 3.3
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
141679 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)
CVE-ID: CVE-2018-1333
DESCRIPTION: Apache HTTP Server is vulnerable to a denial of service. By
sending specially crafted HTTP/2 requests, a remote attacker could exploit this
vulnerability to cause worker exhaustion.
CVSS Base Score: 5.3
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
146701 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVE-ID: CVE-2018-8011
DESCRIPTION: Apache HTTP Server is vulnerable to a denial of service, caused by
a NULL pointer dereference in the mod_md challenge handler. By sending a
specially crafted HTTP request, a remote attacker could exploit this
vulnerability to cause the child process to segfault.
CVSS Base Score: 5.3
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
146700 for more information.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
