Vulnerability Details

CVEID:CVE-2019-13990
**DESCRIPTION:**Terracotta could allow a remote attacker to obtain sensitive information, caused by improper handling of XML external entity (XXE) declarations by the initDocumentParser function in xml/XMLSchedulingDataProcessor.java. By persuading a victim to open specially-crafted XML content, a remote attacker could exploit this vulnerability to read arbitrary files.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/165431 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N)

CVEID:CVE-2020-8908
**DESCRIPTION:**Guava could allow a remote authenticated attacker to bypass security restrictions, caused by a temp directory creation vulnerability in com.google.common.io.Files.createTempDir(). By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass access restrictions.
CVSS Base score: 5.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/192996 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N)

CVEID:CVE-2020-9488
**DESCRIPTION:**Apache Log4j is vulnerable to a man-in-the-middle attack, caused by improper certificate validation with host mismatch in the SMTP appender. An attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to obtain sensitive information or further compromise the system.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/180824 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2020-13956
**DESCRIPTION:**Apache HttpClient could allow a remote attacker to bypass security restrictions, caused by the improper handling of malformed authority component in request URIs. By passing request URIs to the library as java.net.URI object, an attacker could exploit this vulnerability to pick the wrong target host for request execution.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/189572 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-2020-25649
**DESCRIPTION:**FasterXML Jackson Databind could provide weaker than expected security, caused by not having entity expansion secured properly. A remote attacker could exploit this vulnerability to launch XML external entity (XXE) attacks to have impact over data integrity.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/192648 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)
