| N/A | CVE-2023-25194 A possible security vulnerability has been identified in Apache Kafka Connect. This requires access to a Kafka Connect worker, and the ability to create/modify connectors on it with an arbitrary Kafka client SASL JAAS config and a SASL-based security protocol, which has been possible on Kafka Connect clusters since Apache Kafka 2.3.0. When configuring the connector via the Kafka Connect REST API, an authenticated operator can set the `sasl.jaas.config` property for any of the connector's Kafka clients to "com.sun.security.auth.module.JndiLoginModule", which can be done via the `producer.override.sasl.jaas.config`, `consumer.override.sasl.jaas.config`, or `admin.override.sasl.jaas.config` properties. This will allow the server to connect to the attacker's LDAP server and deserialize the LDAP response, which the attacker can use to execute java deserialization gadget chains on the Kafka connect server. Attacker can cause unrestricted deserialization of untrusted data (or) RCE vulnerability when there are gadgets in the classpath. Since Apache Kafka 3.0.0, users are allowed to specify these properties in connector configurations for Kafka Connect clusters running with out-of-the-box configurations. Before Apache Kafka 3.0.0, users may not specify these properties unless the Kafka Connect cluster has been reconfigured with a connector client override policy that permits them. Since Apache Kafka 3.4.0, we have added a system property ("-Dorg.apache.kafka.disallowed.login.modules") to disable the problematic login modules usage in SASL JAAS configuration. Also by default "com.sun.security.auth.module.JndiLoginModule" is disabled in Apache Kafka 3.4.0. We advise the Kafka Connect users to validate connector configurations and only allow trusted JNDI configurations. Also examine connector dependencies for vulnerable versions and either upgrade their connectors, upgrading that specific dependency, or removing the connectors as options for remediation. Finally, in addition to leveraging the "org.apache.kafka.disallowed.login.modules" system property, Kafka Connect users can also implement their own connector client config override policy, which can be used to control which Kafka client properties can be overridden directly in a connector config and which cannot.

| N/A | CVE-2023-0758 A vulnerability was found in glorylion JFinalOA 1.0.2 and classified as critical. This issue affects some unknown processing of the file src/main/java/com/pointlion/mvc/common/model/SysOrg.java. The manipulation of the argument id leads to sql injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-220469 was assigned to this vulnerability.

| N/A | CVE-2023-0575 External Control of Critical State Data, Improper Control of Generation of Code ('Code Injection') vulnerability in YugaByte, Inc. Yugabyte DB on Windows, Linux, MacOS, iOS (DevopsBase.Java:execCommand, TableManager.Java:runCommand modules) allows API Manipulation, Privilege Abuse. This vulnerability is associated with program files backup.Py. This issue affects Yugabyte DB: Lesser then 2.2. Published Thursday, February 9, 2023 |
| N/A | CVE-2023-0745 Relative Path Traversal vulnerability in YugaByte, Inc. Yugabyte Managed (PlatformReplicationManager.Java modules) allows Path Traversal. This vulnerability is associated with program files PlatformReplicationManager.Java. This issue affects Yugabyte Managed: from 2.0 through 2.13. Published Thursday, February 9, 2023 |
| N/A | CVE-2023-24815 Vert.x-Web is a set of building blocks for building web applications in the java programming language. When running vertx web applications that serve files using `StaticHandler` on Windows Operating Systems and Windows File Systems, if the mount point is a wildcard (`*`) then an attacker can exfiltrate any class path resource. When computing the relative path to locate the resource, in case of wildcards, the code: `return "/" + rest;` from `Utils.java` returns the user input (without validation) as the segment to lookup. Even though checks are performed to avoid escaping the sandbox, given that the input was not sanitized `\` are not properly handled and an attacker can build a path that is valid within the classpath. This issue only affects users deploying in windows environments and upgrading is the advised remediation path. There are no known workarounds for this vulnerability.
