Vulnerability Details

CVEID:CVE-2022-3676
**DESCRIPTION:**Eclipse Openj9 could allow a remote attacker to bypass security restrictions, caused by improper runtime type check by the interface calls. By sending a specially-crafted request using bytecode, an attacker could exploit this vulnerability to access or modify memory.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/239608 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-2021-28167
**DESCRIPTION:**Eclipse Openj9 could allow a remote attacker to bypass security restrictions, caused by a flaw in the jdk.internal.reflect.ConstantPool API. By sending a specially-crafted request, an attacker could exploit this vulnerability to call static methods or access static members without running the class initialization method.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/200533 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-2022-21628
**DESCRIPTION:**Java SE is vulnerable to a denial of service, caused by a flaw in the Lightweight HTTP Server. By sending a specially-crafted request, 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/238623 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2022-21626
**DESCRIPTION:**An unspecified vulnerability in Java SE related to the Security component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/238689 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2022-21624
**DESCRIPTION:**An unspecified vulnerability in Java SE related to the Security component could allow an unauthenticated attacker to update, insert or delete data resulting in a low integrity impact using unknown attack vectors.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/238699 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2022-21619
**DESCRIPTION:**An unspecified vulnerability in Java SE related to the Security component could allow an unauthenticated attacker to update, insert or delete data resulting in a low integrity impact using unknown attack vectors.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/238698 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2021-41041
**DESCRIPTION:**Eclipse Openj9 could allow a remote attacker to bypass security restrictions, caused by failing to throw the exception captured during bytecode verification when verification. By sending a specially-crafted request, an attacker could exploit this vulnerability to make unverified methods to be invoked using MethodHandles.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/225398 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)
