Summary
Apache HTTP Server has security vulnerabilities that allows a remote attacker to exploit the 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.
CVEID: CVE-2019-0220
DESCRIPTION: Apache HTTP Server could provide weaker than expected security, caused by URL normalization inconsistencies. A remote attacker could exploit this vulnerability to launch further attacks on the system.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/158948 for the current score
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)
CVEID: CVE-2019-0196
DESCRIPTION: Apache HTTP Server is vulnerable to a denial of service, caused by a use-after-free on a string compare in the mod_http2 module. By sending a specially-crafted request, 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/158963 for the current score
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)
CVEID: CVE-2019-0197
DESCRIPTION: Apache HTTP Server is vulnerable to a denial of service, caused by a flaw when HTTP/2 or H2Upgrade was enabled for http/https host in the mod_http2 module. By sending a specially-crafted request, 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/158964 for the current score
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)
CVEID: CVE-2019-0217
DESCRIPTION: Apache HTTP Server could allow a remote authenticated attacker to bypass security restrictions, caused by a race condition in mod_auth_digest when running in a threaded server. An attacker could exploit this vulnerability to bypass access restrictions.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/158950 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N)
CVEID: CVE-2019-0215
DESCRIPTION: Apache HTTP Server could allow a remote attacker to bypass security restrictions, caused by a bug in mod_ssl. An attacker could exploit this vulnerability to bypass configured access control restrictions.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/158951 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)
DESCRIPTION: Apache HTTP Server could allow a local authenticated attacker to gain elevated privileges on the system, caused by the execution of code in less-privileged child processes or threads from modules' scripts. By manipulating the scoreboard, an attacker could exploit this vulnerability to execute arbitrary code on the system with root privileges.
CVSS Base Score: 8.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/158929 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H)
