Security Bulletin: IBM App Connect Enterprise Certified Container may be vulnerable to multiple denial of service and HTTP request smuggling vulnerabilities

Description

## Summary App Connect Enterprise flows may be susceptible to denial of service attacks due to CVE-2020-1971 and CVE-2020-8265 in the Node.js runtime, and all components may be vulnerable to HTTP request smuggling due to CVE-2020-8287. ## Vulnerability Details ** CVEID: **[CVE-2020-1971](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-1971>) ** DESCRIPTION: **OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference. If the GENERAL_NAME_cmp function contain an EDIPARTYNAME, an attacker could exploit this vulnerability to cause the application to crash. CVSS Base score: 7.5 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/192748](<https://exchange.xforce.ibmcloud.com/vulnerabilities/192748>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) ** CVEID: **[CVE-2020-8265](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-8265>) ** DESCRIPTION: **Node.js is vulnerable to a denial of service, caused by a use-after-free in TLSWrap within the TLS implementation. By writing to a TLS enabled socket, an attacker could exploit this vulnerability to corrupt memory and cause a denial of service. CVSS Base score: 7.5 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/194101](<https://exchange.xforce.ibmcloud.com/vulnerabilities/194101>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) ** CVEID: **[CVE-2020-8287](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-8287>) ** DESCRIPTION: **Node.js is vulnerable to HTTP request smuggling. By sending specially crafted HTTP request headers, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks. CVSS Base score: 7.4 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/194100](<https://exchange.xforce.ibmcloud.com/vulnerabilities/194100>) for the current score.
