Vulnerabilidades

Cross Site Scripting (XSS) vulnerability in CrushFTP 11.3.6_48. The Web-Based Server has a feature where users can share files, the feature reflects the filename to an emailbody field with no sanitations leading to HTML Injection.

CrushFTP11 before 11.3.7_57 is vulnerable to stored HTML injection in the CrushFTP Admin Panel (Reports / "Who Created Folder"), enabling persistent HTML execution in admin sessions.

CrushFTP 10 before 10.8.5 and 11 before 11.3.4_23, when the DMZ proxy feature is not used, mishandles AS2 validation and consequently allows remote attackers to obtain admin access via HTTPS, as exploited in the wild in July 2025.

CrushFTP 9.x and 10.x through 10.8.4 and 11.x through 11.3.1 allows directory traversal via the /WebInterface/function/ URI to read files accessible by SMB at UNC share pathnames, bypassing SecurityManager restrictions.

CrushFTP 9.x and 10.x through 10.8.4 and 11.x through 11.3.1 allows SSRF via the host and port parameters in a command=telnetSocket request to the /WebInterface/function/ URI.

CrushFTP 10 before 10.8.4 and 11 before 11.3.1 allows authentication bypass and takeover of the crushadmin account (unless a DMZ proxy instance is used), as exploited in the wild in March and April 2025, aka "Unauthenticated HTTP(S) port access." A race condition exists in the AWS4-HMAC (compatible with S3)…

CrushFTP 10 before 10.8.3 and 11 before 11.2.3 mishandles password reset, leading to account takeover.

Cross Site Scripting (XSS) vulnerability in CrushFTP v.10.6.0 and v.10.5.5 allows an attacker to execute arbitrary code via a crafted payload.

A server side template injection vulnerability in CrushFTP in all versions before 10.7.1 and 11.1.0 on all platforms allows unauthenticated remote attackers to read files from the filesystem outside of the VFS Sandbox, bypass authentication to gain administrative access, and perform remote code execution on the server.

The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some…

CrushFTP prior to 10.5.1 is vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes.

An issue was discovered in CrushFTP 9. The creation of a new user through the /WebInterface/UserManager/ interface allows an attacker, with access to the administration panel, to perform Stored Cross-Site Scripting (XSS). The payload can be executed in multiple scenarios, for example when the user's page appears in…

CrushFTP through 8.3.0 is vulnerable to credentials theft via URL redirection.

CrushFTP before 7.8.0 and 8.x before 8.2.0 has a redirect vulnerability.

CrushFTP before 7.8.0 and 8.x before 8.2.0 has an HTTP header vulnerability.

CrushFTP before 7.8.0 and 8.x before 8.2.0 has XSS.

CrushFTP 8.x before 8.2.0 has a serialization vulnerability.

Ben Spink CrushFTP FTP Server 2.1.6 and earlier allows a local attacker to access arbitrary files via a '..' (dot dot) attack, or variations, in (1) GET, (2) CD, (3) NLST, (4) SIZE, (5) RETR.
