Security Bulletin
Summary
IBM Virtualization Engine TS7700 is vulnerable to denial of service (CVE-2022-0778) and privilege escalation (CVE-2022-1292) due to the use of OpenSSL. OpenSSL is used by IBM Virtualization Engine TS7700 for inbound and outbound TLS connections other than those provided by the Management Interface. IBM Virtualization Engine TS7700 has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2022-0778
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a flaw in the BN_mod_sqrt() function when parsing certificates. By using a specially-crafted certificate with invalid explicit curve parameters, a remote attacker could exploit this vulnerability to cause an infinite loop, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/221911 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-2022-1292
DESCRIPTION: OpenSSL could allow a remote authenticated attacker to execute arbitrary commands on the system, caused by improper validation of user-supplied input by the c_rehash script. By sending a specially-crafted request using shell metacharacters, an attacker could exploit this vulnerability to execute arbitrary commands with the privileges of the script on the system.
CVSS Base score: 6.3
