What is CVE-2025-47812?
CVE-2025-47812 is a severe remote code execution vulnerability found in the Wing FTP Server, an application designed to facilitate file transfer over the Internet using FTP protocols. This vulnerability resides in the mishandling of the null byte ('\0') within both user and admin web interfaces of versions preceding 7.4.4. As a result, attackers can inject arbitrary Lua code into user session files. This situation places the integrity and confidentiality of the entire system in jeopardy, as it allows the execution of any command with the privileges tied to the FTP service, which typically operates at elevated system levels like root or SYSTEM. The potential for exploitation extends to accounts with anonymous access, further amplifying the risk of unauthorized access and control.
Potential impact of CVE-2025-47812
-
Complete Server Compromise: The ability to execute arbitrary commands means that an attacker can gain full control over the server, potentially leading to unauthorized data access, modification, or deletion. This total compromise can severely damage an organization's operational continuity and reputation.
-
Exploitation via Anonymous Accounts: The vulnerability can be exploited by users with anonymous FTP access, making it easier for threat actors to initiate attacks without needing valid credentials. This lowers the barrier of entry for exploitation and increases the vulnerability's potential impact.
-
Risk of Data Breaches: Successful exploitation of this vulnerability can lead to significant data breaches, exposing sensitive organizational data or personally identifiable information (PII) to malicious actors. The ramifications of such breaches could involve legal ramifications, loss of customer trust, and financial liabilities.
