Node.js is used by the Cordova tools in IBM Rational Application Developer for WebSphere Software. IBM Rational Application Developer for WebSphere Software has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2018-0734 Description: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a timing side channel attack in the DSA signature algorithm. An attacker could exploit this vulnerability using variations in the signing algorithm to recover the private key. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152085 for more information. CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2018-0735 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a timing side channel attack in the ECDSA signature algorithm. An attacker could exploit this vulnerability using variations in the signing algorithm to recover the private key. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 133784 for more information. CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N) CVE-ID: CVE-2018-5407 Description: Multiple SMT/Hyper-Threading architectures and processors could allow a local attacker to obtain sensitive information, caused by execution engine sharing on Simultaneous Multithreading (SMT) architecture. By using the PortSmash new side-channel attack, an attacker could run a malicious process next to legitimate processes using the architectur's parallel thread running capabilities to leak encrypted data from the CPU's internal processes. Note: This vulnerability is known as PortSmash. CVSS Base Score: 5.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152484 for more information. CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N) CVE-ID: CVE-2018-12116 Description: Node.js is vulnerable to HTTP request splitting attacks, caused by improper input validation by the path option of an HTTP request. A remote attacker could exploit this vulnerability to inject arbitrary HTTP request and cause the browser to send 2 HTTP requests, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting. CVSS Base Score: 6.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 153452 for more information. CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) CVE-ID: CVE-2018-12123 Description: Node.js is vulnerable to HTTP request splitting attacks, caused by improper input validation by the path option of an HTTP request. A remote attacker could exploit this vulnerability to inject arbitrary HTTP request and cause the browser to send 2 HTTP requests, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting. CVSS Base Score: 6.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 153457 for more information. CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) CVE-ID: CVE-2018-12120 Description: Node.js could allow a remote attacker to execute arbitrary JavaScript on the system, caused by a flaw when debugger mode is enabled with `node --debug` or `node debug`. By sending specially-crafted request to port 5858, an attacker could exploit this vulnerability to execute arbitrary JavaScript on the system. CVSS Base Score: 9.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 153454 for more information. CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) CVE-ID: CVE-2018-12121 Description: Node.js is vulnerable to a denial of service, caused by improper validation of HTTP headers. By sending specially-crafted HTTP requests with maximum sized headers, a remote attacker could exploit this vulnerability to cause a denial of service condition. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 153455 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:H) CVE-ID: CVE-2018-12122 Description: Node.js is vulnerable to a denial of service, caused by improper validation of HTTP headers. By sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time, 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/ 153456 for more information.
