VEDA MultiPurpose WordPress Theme PHP Object Injection Vulnerability

A PHP Object Injection vulnerability has been identified in the VEDA - MultiPurpose WordPress Theme, affecting all versions through 4.2. This vulnerability arises from the deserialization of untrusted input in the 'veda_backup_and_restore_action' function, allowing authenticated attackers with Subscriber-level access and above to inject a PHP object. While the vulnerable theme itself does not have a known PHP Object Injection chain, the impact could be significant if another plugin or theme with such a chain is installed, potentially enabling the attacker to delete files, access sensitive information, or execute code, depending on the nature of the injected object.

Impact

Exploitation of this vulnerability could lead to PHP Object Injection, allowing for the injection of a PHP object by an authenticated attacker. If a PHP Object Injection chain is present through an additional plugin or theme, it could enable actions such as file deletion, retrieval of sensitive data, or code execution, based on the specifics of the PHP Object Injection chain.

Remediation

No known patch is available. It is recommended to review the vulnerability details and consider uninstalling the affected theme, replacing it with a different one.
