Published: 11 September 2023
Summary
CVE-2023-4314 is a high-severity an unspecified weakness vulnerability in Tms-Outsource Wpdatatables. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 8.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The wpDataTables WordPress plugin before version 2.1.66 contains an insecure deserialization flaw in its handling of "Serialized PHP array" input data. The component fails to validate or sanitize this input prior to deserialization, enabling an authenticated administrator to supply arbitrary serialized objects. The issue is rated 7.2 under CVSS 3.1 and is particularly relevant in multisite deployments where administrative accounts are not intended to obtain code execution.
An attacker with administrative privileges can exploit the vulnerability by submitting a crafted serialized payload through the affected plugin interface. If a usable gadget chain exists in the PHP environment, this leads to remote code execution on the server, allowing the attacker to run arbitrary commands with the privileges of the web server process.
The referenced WPScan advisory identifies the affected plugin versions and indicates that the issue is resolved by updating to wpDataTables 2.1.66 or later. The associated EPSS score has remained flat at 0.0671 with no material increase after disclosure.

on the server. This is impactful in environments where admin users should not be allowed to execute arbitrary code, such as multisite.
