Red Hat Security Advisory 2023-1513-01

Red Hat Security Advisory 2024-1353-03 - An update is now available for Red Hat Process Automation Manager. Issues addressed include code execution, denial of service, and deserialization vulnerabilities.

Atlassian has released software fixes to address four critical flaws in its software that, if successfully exploited, could result in remote code execution. The list of vulnerabilities is below - CVE-2022-1471 (CVSS score: 9.8) - Deserialization vulnerability in SnakeYAML library that can lead to remote code execution in multiple products CVE-2023-22522 (CVSS score

The PyTorch model server contains multiple vulnerabilities that can be chained together to permit an unauthenticated remote attacker arbitrary Java code execution. The first vulnerability is that the management interface is bound to all IP addresses and not just the loop back interface as the documentation suggests. The second vulnerability (CVE-2023-43654) allows attackers with access to the management interface to register MAR model files from arbitrary servers. The third vulnerability is that when an MAR file is loaded, it can contain a YAML configuration file that when deserialized by snakeyaml, can lead to loading an arbitrary Java class.

A flaw was found in Red Hat Single Sign-On for OpenShift container images, which are configured with an unsecured management interface enabled. This flaw allows an attacker to use this interface to deploy malicious code and access and modify potentially sensitive information in the app server configuration.

The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.

### Impact A StackOverflowError can be raised when parsing a malformed crafted message due to an infinite recursion. ### Patches Users should upgrade to 4.1.86.Final ### Workarounds There is no workaround, except using a custom HaProxyMessageDecoder. ### References When parsing a TLV with type = PP2_TYPE_SSL, the value can be again a TLV with type = PP2_TYPE_SSL and so on. The only limitation of the recursion is that the TLV length cannot be bigger than 0xffff because it is encoded in an unsigned short type. Providing a TLV with a nesting level that is large enough will lead to raising of a StackOverflowError. The StackOverflowError will be caught if HAProxyMessageDecoder is used as part of Netty’s ChannelPipeline, but using it directly without the ChannelPipeline will lead to a thrown exception / crash. ### For more information If you have any questions or comments about this advisory: * Open an issue in [netty](https://github.com/netty/netty)

### Summary SnakeYaml's `Constructor` class, which inherits from `SafeConstructor`, allows any type be deserialized given the following line: new Yaml(new Constructor(TestDataClass.class)).load(yamlContent); Types do not have to match the types of properties in the target class. A `ConstructorException` is thrown, but only after a malicious payload is deserialized. ### Severity High, lack of type checks during deserialization allows remote code execution. ### Proof of Concept Execute `bash run.sh`. The PoC uses Constructor to deserialize a payload for RCE. RCE is demonstrated by using a payload which performs a http request to http://127.0.0.1:8000. Example output of successful run of proof of concept: ``` $ bash run.sh [+] Downloading snakeyaml if needed [+] Starting mock HTTP server on 127.0.0.1:8000 to demonstrate RCE nc: no process found [+] Compiling and running Proof of Concept, which a payload that sends a HTTP request to mock web server. [+] An exception is expected. Exc...

Netty project is an event-driven asynchronous network application framework. In versions prior to 4.1.86.Final, a StackOverflowError can be raised when parsing a malformed crafted message due to an infinite recursion. This issue is patched in version 4.1.86.Final. There is no workaround, except using a custom HaProxyMessageDecoder.

IBM Cloud Transformation Advisor 2.0.1 through 3.3.1 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 237214.

SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization. Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using SnakeYaml's SafeConsturctor when parsing untrusted content to restrict deserialization.

Those using java.sql.Statement or java.sql.PreparedStatement in hsqldb (HyperSQL DataBase) to process untrusted input may be vulnerable to a remote code execution attack. By default it is allowed to call any static method of any Java class in the classpath resulting in code execution. The issue can be prevented by updating to 2.7.1 or by setting the system property "hsqldb.method_class_names" to classes which are allowed to be called. For example, System.setProperty("hsqldb.method_class_names", "abc") or Java argument -Dhsqldb.method_class_names="abc" can be used. From version 2.7.1 all classes by default are not accessible except those in java.lang.Math and need to be manually enabled.
