Vulnerability Details

CVEID:CVE-2022-1434
**DESCRIPTION:**OpenSSL is vulnerable to a man-in-the-middle attack, caused by the use of the AAD data as the MAC key in the RC4-MD5 ciphersuite. A remote attacker could exploit this vulnerability to predict the MAC key and launch a man-in-the-middle attack and gain access to the communication channel between endpoints to modify data in transit in such a way that it will pass a MAC integrity check.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/225617 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

CVEID:CVE-2022-1343
**DESCRIPTION:**OpenSSL could allow a remote attacker to bypass security restrictions, caused by a incorrect verification of response signing certificates by the OCSP_basic_verify function. By sending a specially-crafted request using the OCSP_NOCHECKS flag, an attacker could exploit this vulnerability to forge positive verification results.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/225618 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

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
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/225619 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2022-1473
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a resource leakage when decoding certificates and keys by the OPENSSL_LH_flush() function. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/225616 for the current score.
