Lifecycle Timeline
4DescriptionCVE.org
The Webinfos WordPress plugin through 1.2 does not validate the type or name of uploaded files, nor restrict the upload action with any authentication, capability, or nonce check, allowing unauthenticated attackers to upload arbitrary files (including PHP) to a web-accessible directory, leading to remote code execution on servers that execute PHP from the uploads path.
AnalysisAI
Unauthenticated remote code execution in the Webinfos WordPress plugin (versions through 1.2) lets any anonymous attacker upload arbitrary files - including PHP webshells - because the plugin's upload handler enforces no file-type validation, authentication, capability, or nonce checks. On servers that execute PHP from the uploads directory, this yields full server compromise. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target WordPress site has the Webinfos plugin (≤1.2) installed and active, and - critically - that the server executes PHP from the wp-content/uploads directory (the CVE explicitly scopes RCE to 'servers that execute PHP from the uploads path'). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals mostly align toward high real-world risk with one notable divergence. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker discovers a WordPress site running Webinfos, then sends a single crafted HTTP POST to the plugin's unauthenticated upload action carrying a PHP webshell. Because no authentication, nonce, or file-type check applies and the file lands in a web-accessible uploads path that executes PHP, the attacker browses to the uploaded shell and runs arbitrary commands as the web-server user. … |
| Remediation | No fixed version is identified in the available data - the description states the flaw persists 'through 1.2' with no patched release confirmed, so treat this as No vendor-released patch identified at time of analysis and monitor the WPScan advisory (https://wpscan.com/vulnerability/40e78256-6a84-44fc-b35b-26c21317691e/) and the WordPress plugin page for an update. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: immediately deactivate and remove all versions of the Webinfos plugin from affected WordPress installations, then scan wp-content/uploads and review server logs for suspicious PHP files or unauthorized access attempts. …
