Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated account at the low-privilege level within the Client Portal (Pro) plugin - consistent with CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 score is driven by AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, indicating a network-exploitable, low-complexity, low-privilege-authenticated path traversal with high confidentiality impact and no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or obtains a low-privilege account on a WordPress site running Client Portal (Pro) 5.6.2 or earlier, then issues an authenticated HTTP request to the plugin's file download endpoint, substituting a traversal payload such as '../../wp-config.php' for the intended document filename. The plugin returns the raw file contents, yielding database hostname, username, and password. … |
| Remediation | Update the Client Portal (Pro) plugin to a version beyond 5.6.2 per the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/leco-client-portal/vulnerability/wordpress-client-portal-pro-plugin-5-6-2-arbitrary-file-download-vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
