At a glance
CVE-2023-29102 is a high-severity Unrestricted Upload of File with Dangerous Type vulnerability in the Olive One Click Demo Import WordPress plugin, affecting versions <= 1.1.2. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed August 2023, reported by deokhunKim.
Vulnerability Overview
The Olive One Click Demo Import plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the olive_one_click_demo_import_save_file function in versions up to, and including, 1.1.2. This makes it possible for authenticated attackers, with administrator-level privileges and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
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-434: Unrestricted Upload of File with Dangerous Type
Reaching this weakness in Olive One Click Demo Import <= 1.1.2 takes an account at Administrator level or above. An unrestricted file upload lets a caller store a file whose type or destination the application does not properly constrain.
If an uploaded file lands anywhere the server will execute, the flaw becomes remote code execution and the site should be treated as fully compromised. No fixed build of this plugin is recorded for Olive One Click Demo Import yet, so installs running <= 1.1.2 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
An attacker needs Administrator access first, so the firewall sees the attempt as traffic from a logged-in account: 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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
