KTransformers Unsafe Deserialization RCE via balance_serve

KTransformers through 0.5.3 contains an unsafe deserialization vulnerability in the balance_serve backend mode where the scheduler RPC server binds a ZMQ ROUTER socket to all interfaces with no authentication and deserializes incoming messages using pickle.loads() without validation. Attackers can send a crafted pickle payload to the exposed ZMQ socket to execute arbitrary code on the server with the privileges of the ktransformers process.

Laminas Project laminas-http before 2.14.2, and Zend Framework 3.0.0, has a deserialization vulnerability that can lead to remote code execution if the content is controllable, related to the __destruct method of the Zend\Http\Response\Stream class in Stream.php. NOTE: Zend Framework is no longer supported by the maintainer. NOTE: the laminas-http vendor considers this a "vulnerability in the PHP language itself" but has added certain type checking as a way to prevent exploitation in (unrecommended) use cases where attacker-supplied data can be deserialized

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an unauthenticated remote code execution. An unauthenticated remote code execution vulnerability allowed attackers to transfer a serialized Java `SignedObject` object to the Jenkins CLI, that would be deserialized using a new `ObjectInputStream`, bypassing the existing blacklist-based protection mechanism. We're fixing this issue by adding `SignedObject` to the blacklist. We're also backporting the new HTTP CLI protocol from Jenkins 2.54 to LTS 2.46.2, and deprecating the remoting-based (i.e. Java serialization) CLI protocol, disabling it by default.

Retrieval-based-Voice-Conversion-WebUI is a voice changing framework based on VITS. Versions 2.2.231006 and prior are vulnerable to unsafe deserialization. The ckpt_path2 variable takes user input (e.g. a path to a model) and passes it to the extract_small_model function in process_ckpt.py, which uses it to load the model on that path with torch.load, which can lead to unsafe deserialization and remote code execution. As of time of publication, no known patches exist.

Entrust Instant Financial Issuance (IFI) Legacy Remoting Service .NET Remoting RCE

Entrust Instant Financial Issuance (IFI) On Premise software (formerly referred to as CardWizard) versions 5.x, prior to 6.10.5, and prior to 6.11.1 contain an insecure .NET Remoting exposure in the Legacy Remoting Service that is enabled by default. The service registers a TCP remoting channel with SOAP and binary formatters configured at TypeFilterLevel=Full and exposes default ObjectURI endpoints such as logfile.rem, photo.rem, cwPhoto.rem, and reports.rem on a network-reachable remoting port. A remote, unauthenticated attacker who can reach the remoting port can invoke exposed remoting objects to read arbitrary files from the server and coerce outbound authentication, and may achieve arbitrary file write and remote code execution via known .NET Remoting exploitation techniques. This can lead to disclosure of sensitive installation and service-account data and compromise of the affected host.

Snappy vulnerable to PHAR deserialization, allowing remote code execution

Snappy is a PHP library allowing thumbnail, snapshot or PDF generation from a url or a html page. Prior to version 1.4.2, Snappy is vulnerable to PHAR deserialization due to a lack of checking on the protocol before passing it into the `file_exists()` function. If an attacker can upload files of any type to the server he can pass in the phar:// protocol to unserialize the uploaded file and instantiate arbitrary PHP objects. This can lead to remote code execution especially when snappy is used with frameworks with documented POP chains like Laravel/Symfony vulnerable developer code. If a user can control the output file from the `generateFromHtml()` function, it will invoke deserialization. This vulnerability is capable of remote code execution if Snappy is used with frameworks or developer code with vulnerable POP chains. It has been fixed in version 1.4.2.

Bypass of the fix for CVE-2019-0195

A critical unauthenticated remote code execution vulnerability was found all recent versions of Apache Tapestry. The affected versions include 5.4.5, 5.5.0, 5.6.2 and 5.7.0. The vulnerability I have found is a bypass of the fix for CVE-2019-0195. Recap: Before the fix of CVE-2019-0195 it was possible to download arbitrary class files from the classpath by providing a crafted asset file URL. An attacker was able to download the file `AppModule.class` by requesting the URL `http://localhost:8080/assets/something/services/AppModule.class` which contains a HMAC secret key. The fix for that bug was a blacklist filter that checks if the URL ends with `.class`, `.properties` or `.xml`. Bypass: Unfortunately, the blacklist solution can simply be bypassed by appending a `/` at the end of the URL: `http://localhost:8080/assets/something/services/AppModule.class/` The slash is stripped after the blacklist check and the file `AppModule.class` is loaded into the response. This class usually contains the HMAC secret key which is used to sign serialized Java objects. With the knowledge of that key an attacker can sign a Java gadget chain that leads to RCE (e.g. CommonsBeanUtils1 from ysoserial). Solution for this vulnerability: * For Apache Tapestry 5.4.0 to 5.6.1, upgrade to 5.6.2 or later. * For Apache Tapestry 5.7.0, upgrade to 5.7.1 or later.

Apache Seata (incubating): Deserialization of untrusted Data in Apache Seata Server

Deserialization of Untrusted Data vulnerability in Apache Seata (incubating). This security vulnerability is the same as CVE-2024-47552, but the version range described in the CVE-2024-47552 definition is too narrow. This issue affects Apache Seata (incubating): from 2.0.0 before 2.3.0. Severity Justification: The Apache Seata security team assesses the severity of this vulnerability as "Low" due to stringent real-world mitigating factors. First, the vulnerability is strictly isolated to the Raft cluster mode, an optional and non-default feature introduced in v2.0.0, while most users rely on the unaffected traditional architecture. Second, Seata is an internal middleware; communication between TC and RM/TM occurs entirely within trusted internal networks. An attacker would require prior, unauthorized access to the Intranet to exploit this, making external exploitation highly improbable. Users are recommended to upgrade to version 2.3.0, which fixes the issue.

Puzzles | WP Magazine / Review with Store WordPress Theme + RTL <= 4.2.4 - Unauthenticated PHP Object Injection

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.

vLLM Vulnerable to Remote Code Execution via Mooncake Integration

vLLM is a high-throughput and memory-efficient inference and serving engine for LLMs. Versions starting from 0.6.5 and prior to 0.8.5, having vLLM integration with mooncake, are vulnerable to remote code execution due to using pickle based serialization over unsecured ZeroMQ sockets. The vulnerable sockets were set to listen on all network interfaces, increasing the likelihood that an attacker is able to reach the vulnerable ZeroMQ sockets to carry out an attack. vLLM instances that do not make use of the mooncake integration are not vulnerable. This issue has been patched in version 0.8.5.

A Java insecure deserialization vulnerability in Adobe LiveCycle ES4 version 11.0 and earlier allows unauthenticated remote attackers to gain operating system code execution by submitting specially crafted Java serialized objects to a specific URL. Adobe LiveCycle ES4 version 11.0.1 and later may be vulnerable if the application is installed with Java environment 7u21 and earlier. Exploitation of the vulnerability depends on two factors: insecure deserialization methods used in the Adobe LiveCycle application, and the use of Java environments 7u21 and earlier. The code execution is performed in the context of the account that is running the Adobe LiveCycle application. If the account is privileged, exploitation provides privileged access to the operating system. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
