GHSA-C747-J5GC-VWH7

Vulnerability from github – Published: 2025-03-14 09:34 – Updated: 2025-03-14 09:34
VLAI
Details

The CiyaShop - Multipurpose WooCommerce Theme theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.19.0 via deserialization of untrusted input in the 'add_ciyashop_wishlist' and 'ciyashop_get_compare' functions. 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.

Details

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 17.0.3.1; Oracle GraalVM Enterprise Edition: 21.3.2 and 22.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 5.3 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).

GHSA-C78M-C52X-JGWP

Vulnerability from github – Published: 2026-06-12 19:09 – Updated: 2026-06-12 19:09
VLAI
Summary
TYPO3 CMS has Insecure Deserialization via Core API
Details

Problem

TYPO3's cache frontend (VariableFrontend) and persistent key-value store (Registry) deserialized PHP payloads without integrity validation or class restrictions. An attacker with write access to the underlying storage backend (cache store or sys_registry database table) could inject a crafted serialized payload to trigger PHP Object Injection, potentially exploiting a gadget chain to achieve Remote Code Execution or other high-impact effects.

Exploiting this vulnerability requires direct local write access to the storage, such as the SQL database or file system.

Solution

Update to TYPO3 versions 10.4.57 ELTS, 11.5.51 ELTS, 12.4.46 ELTS, 13.4.31 LTS, 14.3.3 LTS that fix the problem described.

Credits

TYPO3 CMS thanks “z3rco”, Chowdhury Faizal Ahammed, Rick Larabee, Vitaly Simonovich, Nozomu Sasaki, Mert Akdag, “tikket”, Shafi Almutairi for reporting this issue, and to TYPO3 core & security team member Oliver Hader for fixing it.

GHSA-C7J6-8R6V-P532

Vulnerability from github – Published: 2021-12-23 00:01 – Updated: 2022-01-04 00:01
VLAI
Details

An issue was discovered in Quest KACE Desktop Authority before 11.2. This vulnerability allows attackers to execute remote code through a deserialization exploitation in the RadAsyncUpload function of ASP.NET AJAX. An attacker can leverage this vulnerability when the encryption keys are known (due to the presence of CVE-2017-11317, CVE-2017-11357, or other means). A default setting for the type whitelisting feature in more current versions of ASP.NET AJAX prevents exploitation.

Mitigation
Architecture and Design Implementation

If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.

Mitigation
Implementation

When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.

Mitigation
Implementation

Explicitly define a final object() to prevent deserialization.

Mitigation
Architecture and Design Implementation
  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
Mitigation
Implementation

Avoid having unnecessary types or gadgets (a sequence of instances and method invocations that can self-execute during the deserialization process, often found in libraries) available that can be leveraged for malicious ends. This limits the potential for unintended or unauthorized types and gadgets to be leveraged by the attacker. Add only acceptable classes to an allowlist. Note: new gadgets are constantly being discovered, so this alone is not a sufficient mitigation.

Mitigation
Architecture and Design Implementation

Employ cryptography of the data or code for protection. However, it's important to note that it would still be client-side security. This is risky because if the client is compromised then the security implemented on the client (the cryptography) can be bypassed.

Mitigation MIT-29
Operation

Strategy: Firewall

Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].

CAPEC-586: Object Injection

An adversary attempts to exploit an application by injecting additional, malicious content during its processing of serialized objects. Developers leverage serialization in order to convert data or state into a static, binary format for saving to disk or transferring over a network. These objects are then deserialized when needed to recover the data/state. By injecting a malformed object into a vulnerable application, an adversary can potentially compromise the application by manipulating the deserialization process. This can result in a number of unwanted outcomes, including remote code execution.
