At a glance

CVE-2022-2798 is a critical-severity Improper Neutralization of Formula Elements in a CSV File vulnerability in the Affiliates Manager WordPress plugin, affecting versions <= 2.9.13. It carries a CVSS score of 9.0 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact).

Vulnerability Overview

The Affiliates Manager plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 2.9.13. This allows [authentication level?] attackers to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-1236: Improper Neutralization of Formula Elements in a CSV File

The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.

Remediation

Update to version 2.9.14, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Affiliates Manager: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Affiliates Manager 2.9.14 closes this, and updating the plugin is the step that ends it.
