Vulnerability Details

CVEID:CVE-2020-7020
**DESCRIPTION:**Elastic Enterprise Search could allow a remote authenticated attacker to obtain sensitive information, caused by not properly preserving security permissions in search queries. By sending a search request, a remote attacker could exploit this vulnerability to disclose the existence of documents.
CVSS Base score: 3.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/190409 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2019-7611
**DESCRIPTION:**Elastic Elasticsearch could allow a remote authenticated attacker to gain elevated privileges on the system, caused by an improper permission issue. By sending a specially-crafted request, an attacker could exploit this vulnerability to gain privileges.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/159335 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2018-3824
**DESCRIPTION:**Elastic X-Pack Machine Learning is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote authenticated attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim’s Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim’s cookie-based authentication credentials.
CVSS Base score: 5.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/150286 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N)

CVEID:CVE-2019-7614
**DESCRIPTION:**Elastic Elasticsearch could allow a remote authenticated attacker to obtain sensitive information, caused by a race condition in the response headers. By sending specially-crafted requests, an attacker could exploit this vulnerability to obtain sensitive information of another user from the response header.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/164510 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2020-7021
**DESCRIPTION:**Elasticsearch could allow a local authenticated attacker to obtain sensitive information, caused by an error when audit logging and the emit_request_body option is enabled. By opening the audit log, a local authenticated attacker could obtain password hashes or authentication tokens and use this information to launch further attacks against the affected system.
CVSS Base score: 1.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196943 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N)
