At a glance
CVE-2015-7806 is a high-severity Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in the Form Manager WordPress plugin, affecting versions < 1.7.3. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account. The issue is fixed in version 1.7.3; sites on affected versions should update now. Disclosed June 2021, reported by Nick Blundell.
Vulnerability Overview
Eval injection vulnerability in the fm_saveHelperGatherItems function in ajax.php in the Form Manager plugin before 1.7.3 for WordPress allows remote attackers to execute arbitrary code via unspecified vectors.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection')
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
Remediation
Update to version 1.7.3, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Form Manager: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Form Manager 1.7.3 closes this, and updating the plugin is the step that ends it.
