This security bulletin contains information about 7 vulnerabilities.
EUVDB-ID: #VU19018
Risk: High
CVSSv3.1:
CVE-ID: CVE-2019-12384
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to software allows the logback-core class to process polymorphic deserialization. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Risk: High
CVSSv3.1:
CVE-ID: CVE-2019-14379
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on a targeted system.
The vulnerability exists due to the "SubTypeValidator.java" file mishandles default typing when Ehcache is used. A remote attacker can send a request that submits malicious input to the targeted system and execute arbitrary code.

Risk: Medium
CVSSv3.1:
CVE-ID: CVE-2019-12086
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a polymorphic typing issue when Default Typing is enabled for an externally exposed JSON endpoint and the service has the mysql-connector-java jar in the classpath. A remote attacker can send a specially crafted JSON message and read arbitrary local files on the server due to the missing "com.mysql.cj.jdbc.admin.MiniAdmin" validation.

Risk: Low
CVSSv3.1:
CVE-ID: CVE-2019-10212
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists in Undertow DEBUG log implementation for io.undertow.request.security that stored user's credentials in plain text in a world-readable file. A local user can view contents of the debug file and gain access to login and passwords of Undertow users.

EUVDB-ID: #VU20066
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2019-3888
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to the Connectors.executeRootHandler:402 logs the HttpServerExchange object at ERROR level using UndertowLogger.REQUEST_LOGGER.undertowRequestFailed(t, exchange), which includes logging of user credentials. A local user can view contents of log files and gain access to credentials in plain text that are stored in them.

Risk: Medium
CVSSv3.1:
CVE-ID: CVE-2019-3868
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a remote attacker to hijack user's session.
The vulnerability exists due to software may use the end user token (access or id token JWT) as a session cookie for browser sessions for OIDC. A remote attacker that has access to the service provider backend can hijack the user's browser session and gain unauthorized access to the application.
