Title: Urgent Security Alert: Active Exploitation of CrushFTP Vulnerability (CVE-2025-31161)
In a concerning development for users of CrushFTP, an authentication bypass vulnerability, identified as CVE-2025-31161, is being actively exploited by malicious actors. This vulnerability affects several versions of the software, specifically those ranging from 10.0.0 to 10.8.3, as well as 11.0.0 to 11.3.0. If successfully exploited, attackers can gain access to sensitive data and, depending on the system’s configuration, potentially achieve full control over the affected systems.
Despite the severity of this issue, it seems to be flying under the radar, garnering far less attention than warranted. Security experts have confirmed instances of active exploitation already underway, raising the urgency for users to take immediate action.
To mitigate this risk, it is strongly recommended that users upgrade their CrushFTP installations to the latest versions: 10.8.4 or 11.3.1. If an immediate update is not feasible, utilizing CrushFTP’s DMZ proxy could serve as a temporary safeguard against potential attacks.
If you or someone you know is using CrushFTP, now is the crucial time to verify the version in use and promptly implement the necessary patches. Given the current landscape of cybersecurity threats, including the rise of ransomware, it would not be surprising to see this vulnerability exploited in future attacks. Stay vigilant and prioritize your security measures to protect your systems and data.
