Apache Log4j <=2.14.1 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled (CVE-2021-44228).

Remedy

As per upstream: - In prior releases confirm that if the JDBC Appender is being used it is not configured to use any protocol other than Java. - Note that only the log4j-core JAR file is impacted by this vulnerability. Applications using only the log4j-api JAR file without the log4j-core JAR file are not impacted by this vulnerability.

A flaw was found in xstream. An unsafe deserialization of user-supplied XML, in conjunction with relying on the default deny list, allows a remote attacker to perform a variety of attacks including a remote code execution of arbitrary code in the context of the JVM running the XStream application. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

1 / 5

Remedy

Depending on the version of XStream used there are various usage patterns that mitigate this flaw, though we would strongly recommend using the allow list approach if at all possible as there are likely more class combinations the deny list approach may not address. Allow list approach ```java XStream xstream = new XStream(); XStream.setupDefaultSecurity(xstream); xstream.allowTypesByWildcard(new String[] {"com.misc.classname"}) ``` Deny list for XStream 1.4.13 ```java xstream.denyTypes(new String[]{ "javax.imageio.ImageIO$ContainsFilter" }); xstream.denyTypes(new Class[]{ java.lang.ProcessBuilder.class }); ``` Deny list for XStream 1.4.7 -> 1.4.12 ```java xstream.denyTypes(new String[]{ "javax.imageio.ImageIO$ContainsFilter" }); xstream.denyTypes(new Class[]{ java.lang.ProcessBuilder.class, java.beans.EventHandler.class, java.lang.ProcessBuilder.class, java.lang.Void.class, void.class }); ``` Deny list for versions prior to XStream 1.4.7 ```java xstream.registerConverter(new Converter() { public boolean canConvert(Class type) { return type != null && (type == java.beans.EventHandler.class || type == java.lang.ProcessBuilder.class || type == java.lang.Void.class || void.class || type.getName().equals("javax.imageio.ImageIO$ContainsFilter") || Proxy.isProxy(type)); } public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) { throw new ConversionException("Unsupported type due to security reasons."); } public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) { throw new ConversionException("Unsupported type due to security reasons."); } }, XStream.PRIORITY_LOW); ```

Impact The vulnerability may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.

Patches If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.17.

Workarounds See workarounds for the different versions covering all CVEs.

References See full information about the nature of the vulnerability and the steps to reproduce it in XStream's documentation for CVE-2021-29505.

Vulnerability in the Advanced Networking Option component of Oracle Database Server. Supported versions that are affected are 12.1.0.2, 12.2.0.1 and 19c. Difficult to exploit vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise Advanced Networking Option. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Advanced Networking Option, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Advanced Networking Option. Note: The July 2021 Critical Patch Update introduces a number of Native Network Encryption changes to deal with vulnerability CVE-2021-2351 and prevent the use of weaker ciphers. Customers should review: "Changes in Native Network Encryption with the July 2021 Critical Patch Update" (Doc ID 2791571.1).
