Exploiting this flaw could enable remote code execution on the affected server, potentially leading to full site compromise and further malicious activity.

According to CrowdSec data, while opportunistic exploitation dominates, a portion of threat actors trying to exploit CVE-2024-8425 apply basic targeting methods such as port or service detection. This indicates emerging patterns of selective targeting. In addition, according to the CrowdSec network, attack volume against CVE-2024-8425 has dipped slightly compared to the previous week. Although still commonly targeted, the decline suggests a cooling-off period. Long-term relevance remains, but attention is waning.

Attackers exploit the WooCommerce Ultimate Gift Card plugin by sending POST requests to /wp-admin/admin-ajax.php with the action=mwb_wgm_preview_mail parameter, uploading arbitrary files that are then accessible under /wp-content/uploads/mwb_browse/.
