CVE-2018-12122, CVE-2018-12121, CVE-2018-12123 Vulnerability Details CVEID: 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 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-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 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-2018-12123 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 the current score 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) Affected Products and Versions IBM Cloud Transformation Advisor 1.8.0, 1.8.1, 1.9.0, 1.9.1 Remediation/Fixes Upgrade to 1.9.2 or later.
