Title
GiveWP – Donation Plugin and Fundraising Platform <= 3.14.1 - Unauthenticated PHP Object Injection to Remote Code Execution
Summary
The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.14.1 via deserialization of untrusted input from the 'give_title' parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code remotely, and to delete arbitrary files.

CVE-2024-5871 (GCVE-0-2024-5871)

Vulnerability from cvelistv5 – Published: 2024-06-15 03:35 – Updated: 2026-04-08 17:35

Title
WooCommerce - Social Login <= 2.6.2 - Unauthenticated PHP Object Injection
Summary
The WooCommerce - Social Login plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.6.2 via deserialization of untrusted input from the 'woo_slg_verify' vulnerable parameter. 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.

Title
Timeline Event History <= 3.1 - Authenticated (Contributor+) PHP Object Injection
Summary
The Timeline Event History plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1 via deserialization of untrusted input 'timelines-data' parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, 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.

CVE-2024-5649 (GCVE-0-2024-5649)

Vulnerability from cvelistv5 – Published: 2024-06-19 03:12 – Updated: 2026-04-08 17:06

Title
Universal Slider <= 1.6.5 - Authenticated (Contributor+) PHP Object Injection
Summary
The Universal Slider plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.6.5 via deserialization of untrusted input 'fsl_get_gallery_value' function. This makes it possible for authenticated attackers, with Contributor-level access and above, 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.

Title
Allegra loadFieldMatch Deserialization of Untrusted Data Remote Code Execution Vulnerability
Summary
Allegra loadFieldMatch Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Allegra. Authentication is required to exploit this vulnerability. The specific flaw exists within the loadFieldMatch method. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of LOCAL SERVICE. Was ZDI-CAN-23452.

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.
