Rejetto HFS < 3.2.1 Limited File Disclosure via Path Traversal in lang Parameter

Rejetto HFS 3.0.0 through 3.2.0 allows path traversal through the lang query parameter, permitting a remote unauthenticated attacker to read certain JSON files outside the shared folders. Exploitation is constrained to files matching a narrow naming and format pattern, limiting practical impact.

Rejetto HFS < 3.2.1 Stored XSS via File Names in Basic Web Listing

Rejetto HFS 3.0.0 through 3.2.0 does not escape file names in its fallback "basic" web listing, and this listing can be forced by any browser via the ?get=basic parameter. A user with upload permission - or an anonymous user on servers with an open upload folder - can store a file whose name contains script that executes in the browser of anyone viewing the listing.

Rejetto HFS < 3.2.1 Username Enumeration via Login Response Differences

Rejetto HFS 3.0.0 through 3.2.0 returns observably different responses from its login endpoint depending on whether the submitted username exists. A remote unauthenticated attacker can use this to confirm valid account names, including the default admin account, facilitating password-guessing and session-forgery attacks.

Rejetto HFS < 3.2.1 Cross-Site Request Forgery via GET Requests

Rejetto HFS 3.0.0 through 3.2.0 accepts state-changing API requests via the GET method and exempts GET requests from its anti-CSRF header check. A remote attacker can perform administrative actions including account creation and configuration changes leading to code execution - by causing a logged-in administrator's browser to navigate to a crafted URL, or without any credentials against default installations when the attack originates from the server's own machine.

Rejetto HFS < 3.2.1 Stored XSS in Admin Log Viewer

Rejetto HFS 3.0.0 through 3.2.0 renders log entries in the administration panel as HTML without sanitization. A remote unauthenticated attacker can submit a failed login with a crafted username that is written to the error log and executes JavaScript in an administrator's browser when the logs are viewed, allowing the attacker to create accounts or execute code on the server with the administrator's privileges.

Rejetto HFS < 3.2.1 Session Forgery via Predictable Signing Key

Rejetto HFS 3.0.0 through 3.2.0 derives its session-cookie signing key from the non-cryptographic Math.random() generator and discloses outputs of the same generator to unauthenticated clients during login. A remote attacker can collect a small number of login responses, reconstruct the generator's state, recover the signing key, and forge a valid administrator session cookie, leading to full administrative access and remote code execution via the server_code configuration feature.

The findMacroMarker function in parserLib.pas in Rejetto HTTP File Server (aks HFS or HttpFileServer) 2.3x before 2.3c allows remote attackers to execute arbitrary programs via a %00 sequence in a search action.

Multiple vulnerabilities in Rejetto's Http File Server

An open redirect vulnerability, the exploitation of which could allow an attacker to create a custom URL and redirect a legitimate page to a malicious site.

Multiple vulnerabilities in Rejetto's Http File Server

The software does not neutralize or incorrectly neutralizes certain characters before the data is included in outgoing HTTP headers. The inclusion of invalidated data in an HTTP header allows an attacker to specify the full HTTP response represented by the browser. An attacker could control the response and craft attacks such as cross-site scripting and cache poisoning attacks.

Rejetto HTTP File Server 2.3m Unauthenticated RCE

Rejetto HTTP File Server, up to and including version 2.3m, is vulnerable to a template injection vulnerability. This vulnerability allows a remote, unauthenticated attacker to execute arbitrary commands on the affected system by sending a specially crafted HTTP request. As of the CVE assignment date, Rejetto HFS 2.3m is no longer supported.

The file comment feature in Rejetto HTTP File Server (hfs) 2.3c and earlier allows remote attackers to execute arbitrary code by uploading a file with certain invalid UTF-8 byte sequences that are interpreted as executable macro symbols.

rejetto HFS (aka HTTP File Server) 3 before 0.52.10 on Linux, UNIX, and macOS allows OS command execution by remote authenticated users (if they have Upload permissions). This occurs because a shell is used to execute df (i.e., with execSync instead of spawnSync in child_process in Node.js).

rejetto HFS (aka HTTP File Server) v2.3m Build #300, when virtual files or folders are used, allows remote attackers to trigger an invalid-pointer write access violation via concurrent HTTP requests with a long URI or long HTTP headers.
