Ratpack is a toolkit for creating web applications. In versions prior to 1.9.0, a malicious attacker can achieve Remote Code Execution (RCE) via a maliciously crafted Java deserialization gadget chain leveraged against the Ratpack session store. If one's application does not use Ratpack's session mechanism, it is not vulnerable. Ratpack 1.9.0 introduces a strict allow-list mechanism that mitigates this vulnerability when used. Two possible workarounds exist. The simplest mitigation for users of earlier versions is to reduce the likelihood of attackers being able to write to the session data store. Alternatively or additionally, the allow-list mechanism could be manually back ported by providing an alternative implementation of `SessionSerializer` that uses an allow-list.

A remote insecure deserialization vulnerability was discovered in Aruba ClearPass Policy Manager version(s): Prior to 6.10.0, 6.9.6 and 6.8.9. Aruba has released updates to ClearPass Policy Manager that address this security vulnerability.

The Album Gallery – WordPress Gallery plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.6.3 via deserialization of untrusted input from gallery meta. This makes it possible for authenticated attackers, with Editor-level access and above, 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 Ocean Extra WordPress plugin before 2.0.5 unserialises the content of an imported file, which could lead to PHP object injections issues when a high privilege user import (intentionally or not) a malicious Customizer Styling file and a suitable gadget chain is present on the blog.

The Customizer Export/Import WordPress plugin before 0.9.5 unserializes the content of an imported file, which could lead to PHP object injection issues when an admin imports (intentionally or not) a malicious file and a suitable gadget chain is present on the blog.

PHP Object Injection vulnerability in Easy Digital Downloads plugin <= 3.0.1 at WordPress.

USU Oracle Optimization before 5.17 allows authenticated quantum users to achieve remote code execution because of /v2/quantum/save-data-upload-big-file Java deserialization. NOTE: this is not an Oracle Corporation product.

In WhatsUp Gold versions released before 2023.1.3, Distributed Edition installations can be exploited by using a deserialization tool to achieve a Remote Code Execution as SYSTEM.  The vulnerability exists in the main message processing routines NmDistributed.DistributedServiceBehavior.OnMessage for server and NmDistributed.DistributedClient.OnMessage for clients.

A vulnerability has been identified in SINEC NMS (All versions < V1.0 SP2 Update 1). The affected system allows to upload JSON objects that are deserialized to JAVA objects. Due to insecure deserialization of user-supplied content by the affected software, a privileged attacker could exploit this vulnerability by sending a crafted serialized Java object. An exploit could allow the attacker to execute arbitrary code on the device with root privileges.

IBM ManageIQ could allow a remote authenticated attacker to execute arbitrary commands on the system by sending a specially crafted yaml file request.

Microsoft SharePoint Server Remote Code Execution Vulnerability

Tenable.sc and Tenable.sc Core versions 5.13.0 through 5.17.0 were found to contain a vulnerability that could allow an authenticated, unprivileged user to perform Remote Code Execution (RCE) on the Tenable.sc server via Hypertext Preprocessor unserialization.

Deserialization of Untrusted Data vulnerability in WP All Import Import Users from CSV.This issue affects Import Users from CSV: from n/a through 1.2.

Microsoft SharePoint Server Remote Code Execution Vulnerability

IBM QRadar 7.3.0 to 7.3.3 Patch 2 could allow an authenticated user to send a specially crafted command which would be executed as a lower privileged user. IBM X-ForceID: 175897.

IBM QRadar 7.3.0 to 7.3.3 Patch 2 could allow a remote attacker to include arbitrary files. A remote attacker could send a specially-crafted request specify a malicious file from a remote system, which could allow the attacker to execute arbitrary code on the vulnerable server. IBM X-ForceID: 175898.

The Easy WP SMTP WordPress plugin before 1.5.0 unserialises the content of an imported file, which could lead to PHP object injection issue when an admin import (intentionally or not) a malicious file and a suitable gadget chain is present on the blog.
