Vulnerability from csaf_redhat - Published: 2019-10-10 09:54 - Updated: 2024-11-15 05:17Summary
Red Hat Security Advisory: Red Hat OpenShift Application Runtimes Thorntail 2.5.0 security & bug fix update
Severity
Important
Notes
Topic: An update is now available for Red Hat OpenShift Application Runtimes.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: Red Hat OpenShift Application Runtimes provides an application platform that reduces the complexity of developing and operating applications (monoliths and microservices) for OpenShift as a containerized platform.
This release of RHOAR Thorntail 2.5.0 serves as a replacement for RHOAR Thorntail 2.4.0, and includes security and bug fixes and enhancements. For further information, refer to the release notes linked to in the References section.
Security Fix(es):
* keycloak: session hijack using the user access token (CVE-2019-3868)
* undertow: leak credentials to log files UndertowLogger.REQUEST_LOGGER.undertowRequestFailed (CVE-2019-3888)
* undertow: Information leak in requests for directories without trailing slashes (CVE-2019-10184)
* jackson-databind: polymorphic typing issue allows attacker to read arbitrary local files on the server (CVE-2019-12086)
* jackson-databind: failure to block the logback-core class from polymorphic deserialization leading to remote code execution (CVE-2019-12384)
* undertow: DEBUG log for io.undertow.request.security if enabled leaks credentials to log files (CVE-2019-10212)
* jackson-databind: default typing mishandling leading to remote code execution (CVE-2019-14379)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Keycloak up to version 6.0.0 allows the end user token (access or id token JWT) to be used as the session cookie for browser sessions for OIDC. As a result an attacker with access to service provider backend could hijack user’s browser session.
CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor
Vendor Fix
Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on.
The References section of this erratum contains a download link (you must log in to download the update).
https://access.redhat.com/errata/RHSA-2019:2998
A vulnerability was found in Undertow web server before 2.0.21. An information exposure of plain text credentials through log files because Connectors.executeRootHandler:402 logs the HttpServerExchange object at ERROR level using UndertowLogger.REQUEST_LOGGER.undertowRequestFailed(t, exchange)
5.3 (Medium)
Vendor Fix
Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on.
The References section of this erratum contains a download link (you must log in to download the update).
https://access.redhat.com/errata/RHSA-2019:2998
undertow before version 2.0.23.Final is vulnerable to an information leak issue. Web apps may have their directory structures predicted through requests without trailing slashes via the api.
5.3 (Medium)
Vendor Fix
Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on.
The References section of this erratum contains a download link (you must log in to download the update).
https://access.redhat.com/errata/RHSA-2019:2998
A flaw was found in the Undertow DEBUG log for io.undertow.request.security. If enabled, an attacker could abuse this flaw to obtain the user’s credentials from the log files.
4.8 (Medium)
Vendor Fix
Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on.
The References section of this erratum contains a download link (you must log in to download the update).
https://access.redhat.com/errata/RHSA-2019:2998
Workaround
Use Elytron instead of legacy Security subsystem.
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has the mysql-connector-java jar (8.0.14 or earlier) in the classpath, and an attacker can host a crafted MySQL server reachable by the victim, an attacker can send a crafted JSON message that allows them to read arbitrary local files on the server. This occurs because of missing com.mysql.cj.jdbc.admin.MiniAdmin validation.
7.5 (High)
Vendor Fix
Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on.
The References section of this erratum contains a download link (you must log in to download the update).
https://access.redhat.com/errata/RHSA-2019:2998
Workaround
The following conditions are needed for an exploit, we recommend avoiding all if possible
* Deserialization from sources you do not control
* `enableDefaultTyping()`
* `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS`
A flaw was discovered in FasterXML jackson-databind in versions prior to 2.9.9. The vulnerability would permit polymorphic deserialization of malicious objects using the logback-core gadget when used in conjunction with polymorphic type handling methods such as `enableDefaultTyping()` or when @JsonTypeInfo is using `Id.CLASS` or `Id.MINIMAL_CLASS` or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. Depending on the classpath content, remote code execution may be possible.
8.1 (High)
Vendor Fix
Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on.

Workaround
The following conditions are needed for an exploit, we recommend avoiding all if possible:
* Deserialization from sources you do not control
* `enableDefaultTyping()`
* `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS`
A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the ehcache and logback JNDI gadgets when used in conjunction with polymorphic type handling methods such as `enableDefaultTyping()` or when @JsonTypeInfo is using `Id.CLASS` or `Id.MINIMAL_CLASS` or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.
