Vulnerability Details
CVEID: CVE-2018-7160
DESCRIPTION: Node.js inspector module could allow a remote attacker to bypass
security restrictions, caused by the failure to properly validate the Host
header. An attacker could exploit this vulnerability to bypass same-origin
policy and conduct a DNS rebinding attack.
CVSS Base Score: 5.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
143447 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:L)
CVEID: CVE-2018-7159
DESCRIPTION: Node.js http module could allow a remote attacker to bypass
security restrictions, caused by the acceptance of incorrect Content-Length
values, containing spaces within the value, in HTTP headers. An attacker could
exploit this vulnerability to confuse the script and launch further attacks on
the system.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
143448 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-2018-7158
DESCRIPTION: Node.js path module is vulnerable to a denial of service. By
sending a specially crafted file path, an attacker could exploit this
vulnerability to cause a regular expression denial of service.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
143449 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2018-7167
DESCRIPTION: Node.js is vulnerable to a denial of service. By invoking
Buffer.fill() or Buffer.alloc() , a remote attacker could exploit this
vulnerability to cause the application to hang.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
144740 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:H)
CVEID: CVE-2018-7164
DESCRIPTION: Node.js is vulnerable to a denial of service, caused by an error
when reading from the network into JavaScript using the net.Socket object
directly as a stream. By sending tiny chunks of data in short succession, a
remote attacker could exploit this vulnerability to cause the application to
exhaust all memory resources.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
144739 for the current score

CVEID: CVE-2018-7162
DESCRIPTION: Node.js is vulnerable to a denial of service. By sending
duplicate/unexpected messages during the handshake, a remote attacker could
exploit this vulnerability to cause the node server providing an http server
supporting TLS server to crash.
CVSS Base Score: 7.5
