CVE-2026-60105 Details
Description
Monsta FTP before 2.14.5 contains a server-side request forgery vulnerability in the fetchRemoteFile action caused by an incomplete IP blocklist check in the isBlockedIP() function, which fails to detect embedded IPv4 addresses within IPv4-mapped IPv6 addresses. An unauthenticated attacker can obtain a CSRF token from the public getSystemVars endpoint and submit a fetchRemoteFile request with a source URL resolving to an IPv4-mapped address, causing the server to issue HTTP requests to internal services and write responses to an attacker-controlled FTP destination, enabling retrieval of cloud instance metadata credentials.
A server-side request forgery (SSRF) vulnerability has been identified in Monsta FTP versions prior to 2.14.5. The issue arises in the fetchRemoteFile action, where an incomplete IP blocklist check in the isBlockedIP() function fails to recognize embedded IPv4 addresses within IPv4-mapped IPv6 addresses. This allows an unauthenticated attacker to obtain a CSRF token from the public getSystemVars endpoint and send a fetchRemoteFile request with a source URL that resolves to an IPv4-mapped address. Consequently, the server makes HTTP requests to internal services and directs the responses to an attacker-controlled FTP destination, facilitating the retrieval of cloud instance metadata credentials.
