FasterXML jackson-databind 2.x before 2.9.10.8 mishandles the interaction between serialization gadgets and typing, related to com.oracle.wls.shaded.org.apache.xalan.lib.sql.JNDIConnectionPool (aka embedded Xalan in org.glassfish.web/javax.servlet.jsp.jstl).

MyBatis before 3.5.6 mishandles deserialization of object streams.

Multiple vulnerabilities in the Java deserialization function that is used by Cisco Security Manager could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected device. These vulnerabilities are due to insecure deserialization of user-supplied content by the affected software. An attacker could exploit these vulnerabilities by sending a malicious serialized Java object to a specific listener on an affected system. A successful exploit could allow the attacker to execute arbitrary commands on the device with the privileges of NT AUTHORITY\SYSTEM on the Windows target host. Cisco has not released software updates that address these vulnerabilities.

An Improper Input Validation vulnerability in the J-Web component of Juniper Networks Junos OS may allow an unauthenticated attacker to access data without proper authorization. Utilizing a crafted POST request, deserialization may occur which could lead to unauthorized local file access or the ability to execute arbitrary commands. This issue affects Juniper Networks Junos OS: all versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R3-S6; 19.3 versions prior to 19.3R3-S7; 19.4 versions prior to 19.4R2-S7, 19.4R3-S9; 20.1 versions prior to 20.1R3-S5; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R2-S2, 21.3R3; 21.4 versions prior to 21.4R1-S2, 21.4R2-S1, 21.4R3; 22.1 versions prior to 22.1R1-S1, 22.1R2.

A serialization vulnerability in Zoho ManageEngine Applications Manager before build 13740 allows for remote code execution on Windows via a payload on an SMB share.

In Laravel Framework through 5.5.40 and 5.6.x through 5.6.29, remote code execution might occur as a result of an unserialize call on a potentially untrusted X-XSRF-TOKEN value. This involves the decrypt method in Illuminate/Encryption/Encrypter.php and PendingBroadcast in gadgetchains/Laravel/RCE/3/chain.php in phpggc. The attacker must know the application key, which normally would never occur, but could happen if the attacker previously had privileged access or successfully accomplished a previous attack.

The REST Plugin in Apache Struts 2.1.1 through 2.3.x before 2.3.34 and 2.5.x before 2.5.13 uses an XStreamHandler with an instance of XStream for deserialization without any type filtering, which can lead to Remote Code Execution when deserializing XML payloads.

In Gradle Enterprise before 2021.1.3, a crafted request can trigger deserialization of arbitrary unsafe Java objects. The attacker must have the encryption and signing keys.

Pterodactyl is an open-source game server management panel built with PHP 7, React, and Go. A malicious user can modify the contents of a `confirmation_token` input during the two-factor authentication process to reference a cache value not associated with the login attempt. In rare cases this can allow a malicious actor to authenticate as a random user in the Panel. The malicious user must target an account with two-factor authentication enabled, and then must provide a correct two-factor authentication token before being authenticated as that user. Due to a validation flaw in the logic handling user authentication during the two-factor authentication process a malicious user can trick the system into loading credentials for an arbitrary user by modifying the token sent to the server. This authentication flaw is present in the `LoginCheckpointController@__invoke` method which handles two-factor authentication for a user. This controller looks for a request input parameter called `confirmation_token` which is expected to be a 64 character random alpha-numeric string that references a value within the Panel's cache containing a `user_id` value. This value is then used to fetch the user that attempted to login, and lookup their two-factor authentication token. Due to the design of this system, any element in the cache that contains only digits could be referenced by a malicious user, and whatever value is stored at that position would be used as the `user_id`. There are a few different areas of the Panel that store values into the cache that are integers, and a user who determines what those cache keys are could pass one of those keys which would cause this code pathway to reference an arbitrary user. At its heart this is a high-risk login bypass vulnerability. However, there are a few additional conditions that must be met in order for this to be successfully executed, notably: 1.) The account referenced by the malicious cache key must have two-factor authentication enabled. An account without two-factor authentication would cause an exception to be triggered by the authentication logic, thusly exiting this authentication flow. 2.) Even if the malicious user is able to reference a valid cache key that references a valid user account with two-factor authentication, they must provide a valid two-factor authentication token. However, due to the design of this endpoint once a valid user account is found with two-factor authentication enabled there is no rate-limiting present, thusly allowing an attacker to brute force combinations until successful. This leads to a third condition that must be met: 3.) For the duration of this attack sequence the cache key being referenced must continue to exist with a valid `user_id` value. Depending on the specific key being used for this attack, this value may disappear quickly, or be changed by other random user interactions on the Panel, outside the control of the attacker. In order to mitigate this vulnerability the underlying authentication logic was changed to use an encrypted session store that the user is therefore unable to control the value of. This completely removed the use of a user-controlled value being used. In addition, the code was audited to ensure this type of vulnerability is not present elsewhere.

SuperMartijn642's Config Lib is a library used by a number of mods for the game Minecraft. The versions of SuperMartijn642's Config Lib between 1.0.4 and 1.0.8 are affected by a vulnerability and can be exploited on both servers and clients. Using SuperMartijn642's Config Lib, servers will send a packet to clients with the server's config values. In order to read `enum` values from the packet data, `ObjectInputStream#readObject` is used. `ObjectInputStream#readObject` will instantiate a class based on the input data. Since, the packet data is not validated before `ObjectInputStream#readObject` is called, an attacker can instantiate any class by sending a malicious packet. If a suitable class is found, the vulnerability can lead to a number of exploits, including remote code execution. Although the vulnerable packet is typically only send from server to client, it can theoretically also be send from client to server. This means both clients and servers running SuperMartijn642's Config Lib between 1.0.4 and 1.0.8 are vulnerable. The vulnerability has been patched in SuperMartijn642's Config lib 1.0.9. Both, players and server owners, should update to 1.0.9 or higher.

An issue was discovered in Pivotal Spring Security 4.2.0.RELEASE through 4.2.2.RELEASE, and Spring Security 5.0.0.M1. When configured to enable default typing, Jackson contained a deserialization vulnerability that could lead to arbitrary code execution. Jackson fixed this vulnerability by blacklisting known "deserialization gadgets." Spring Security configures Jackson with global default typing enabled, which means that (through the previous exploit) arbitrary code could be executed if all of the following is true: (1) Spring Security's Jackson support is being leveraged by invoking SecurityJackson2Modules.getModules(ClassLoader) or SecurityJackson2Modules.enableDefaultTyping(ObjectMapper); (2) Jackson is used to deserialize data that is not trusted (Spring Security does not perform deserialization using Jackson, so this is an explicit choice of the user); and (3) there is an unknown (Jackson is not blacklisting it already) "deserialization gadget" that allows code execution present on the classpath. Jackson provides a blacklisting approach to protecting against this type of attack, but Spring Security should be proactive against blocking unknown "deserialization gadgets" when Spring Security enables default typing.

The Java implementation of GraniteDS, version 3.1.1.GA, AMF3 deserializers derives class instances from java.io.Externalizable rather than the AMF3 specification's recommendation of flash.utils.IExternalizable. A remote attacker with the ability to spoof or control an RMI server connection may be able to send serialized Java objects that execute arbitrary code when deserialized.

The Java implementation of AMF3 deserializers used in GraniteDS, version 3.1.1.G, may allow instantiation of arbitrary classes via their public parameter-less constructor and subsequently call arbitrary Java Beans setter methods. The ability to exploit this vulnerability depends on the availability of classes in the class path that make use of deserialization. A remote attacker with the ability to spoof or control information may be able to send serialized Java objects with pre-set properties that result in arbitrary code execution when deserialized.

Deserialization of Untrusted Data vulnerability in plainware.com PlainInventory allows Object Injection.This issue affects PlainInventory: from n/a through 3.1.6.

All versions of package ajaxpro.2 are vulnerable to Deserialization of Untrusted Data due to the possibility of deserialization of arbitrary .NET classes, which can be abused to gain remote code execution.

The Puzzles | WP Magazine / Review with Store WordPress Theme + RTL theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.2.4 via deserialization of untrusted input 'view_more_posts' AJAX action. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. The developer opted to remove the software from the repository, so an update is not available and it is recommended to find a replacement software.

The Hash Form – Drag & Drop Form Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.1.0 via deserialization of untrusted input in the 'process_entry' function. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

The LearnPress WordPress plugin before 4.1.7.2 unserialises user input in a REST API endpoint available to unauthenticated users, which could lead to PHP Object Injection when a suitable gadget is present, leadint to remote code execution (RCE). To successfully exploit this vulnerability attackers must have knowledge of the site secrets, allowing them to generate a valid hash via the wp_hash() function.

NetMotion Mobility before 11.73 and 12.x before 12.02 allows unauthenticated remote attackers to execute arbitrary code as SYSTEM because of Java deserialization in RpcServlet.

Deserialization of Untrusted Data vulnerability in Apache Lucene.Net.Replicator. This issue affects Apache Lucene.NET's Replicator library: from 4.8.0-beta00005 through 4.8.0-beta00016. An attacker that can intercept traffic between a replication client and server, or control the target replication node URL, can provide a specially-crafted JSON response that is deserialized as an attacker-provided exception type. This can result in remote code execution or other potential unauthorized access. Users are recommended to upgrade to version 4.8.0-beta00017, which fixes the issue.

Kafka UI is an Open-Source Web UI for Apache Kafka Management. Kafka UI API allows users to connect to different Kafka brokers by specifying their network address and port. As a separate feature, it also provides the ability to monitor the performance of Kafka brokers by connecting to their JMX ports. JMX is based on the RMI protocol, so it is inherently susceptible to deserialization attacks. A potential attacker can exploit this feature by connecting Kafka UI backend to its own malicious broker. This vulnerability affects the deployments where one of the following occurs: 1. dynamic.config.enabled property is set in settings. It's not enabled by default, but it's suggested to be enabled in many tutorials for Kafka UI, including its own README.md. OR 2. an attacker has access to the Kafka cluster that is being connected to Kafka UI. In this scenario the attacker can exploit this vulnerability to expand their access and execute code on Kafka UI as well. Instead of setting up a legitimate JMX port, an attacker can create an RMI listener that returns a malicious serialized object for any RMI call. In the worst case it could lead to remote code execution as Kafka UI has the required gadget chains in its classpath. This issue may lead to post-auth remote code execution. This is particularly dangerous as Kafka-UI does not have authentication enabled by default. This issue has been addressed in version 0.7.2. All users are advised to upgrade. There are no known workarounds for this vulnerability. These issues were discovered and reported by the GitHub Security lab and is also tracked as GHSL-2023-230.

When configured to enable default typing, Jackson contained a deserialization vulnerability that could lead to arbitrary code execution. Jackson fixed this vulnerability by blacklisting known "deserialization gadgets". Spring Batch configures Jackson with global default typing enabled which means that through the previous exploit, arbitrary code could be executed if all of the following is true: * Spring Batch's Jackson support is being leveraged to serialize a job's ExecutionContext. * A malicious user gains write access to the data store used by the JobRepository (where the data to be deserialized is stored). In order to protect against this type of attack, Jackson prevents a set of untrusted gadget classes from being deserialized. Spring Batch should be proactive against blocking unknown "deserialization gadgets" when enabling default typing.
