## What is CVE-2022-3342?

CVE-2022-3342 is a high-severity unsafe deserialization vulnerability in automattic Jetpack CRM – Clients, Leads, Invoices, Billing, Email Marketing, & Automation, published on 20 Oct 2023. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

The Jetpack CRM plugin for WordPress is vulnerable to PHAR deserialization via the ‘zbscrmcsvimpf’ parameter in the 'zeroBSCRM_CSVImporterLitehtml_app' function in versions up to, and including, 5.3.1. While the function performs a nonce check, steps 2 and 3 of the check do not take any action upon a failed check. These steps then perform a 'file_exists' check on the value of 'zbscrmcsvimpf'. If a phar:// archive is supplied, its contents will be deserialized and an object injected in the execution stream. This allows an unauthenticated attacker to obtain object injection if they are able to upload a phar archive (for instance if the site supports image uploads) and then trick an administrator into performing an action, such as clicking a link.

Weakness: CWE-502 (Deserialization of Untrusted Data)
