CVE-2024-1708 is a path traversal vulnerability in ConnectWise ScreenConnect affecting version 23.9.7 and earlier. The flaw allows file writes outside directories intended by the application due to improper limitation of a pathname to a restricted directory. Available reporting indicates the vulnerable condition can be abused through ScreenConnect's extension-related functionality, allowing a malicious extension or equivalent write operation to place files outside its expected subdirectory. This can be leveraged to achieve remote code execution on the ScreenConnect server or to alter or access sensitive application and system data. The vulnerability requires administrative privileges to exploit directly, but it has been widely discussed in conjunction with CVE-2024-1709, an authentication bypass flaw that can be chained to obtain the necessary administrative access first.

Repository contains a small, focused exploit PoC for chained ConnectWise ScreenConnect vulnerabilities CVE-2024-1708 and CVE-2024-1709. Structure is minimal: a README with technical background, affected versions, reproduction steps, and mitigation guidance, plus a single Python exploit script. The exploit is not part of a larger framework. The Python script automates a 3-step attack chain against a remote ScreenConnect server: (1) probe the path traversal/auth bypass by requesting /SetupWizard.aspx/../../ScreenConnect/Login.aspx, (2) upload a randomly named ASPX webshell to /SetupWizard.aspx/../../ScreenConnect/UploadFile.aspx, optionally reusing a session cookie from the probe response, and (3) execute an arbitrary command by requesting the uploaded shell with ?cmd=<command>. The script supports HTTP or HTTPS, configurable target/port, and defaults to command execution of 'whoami'. The embedded payload is a C#/ASPX webshell that invokes cmd.exe /c <command> and returns stdout/stderr to the HTTP response. This makes the exploit operational rather than a simple detector: it provides direct remote command execution and persistence via a leftover webshell file. The code appears primarily tailored to Windows targets because the payload explicitly launches cmd.exe, although the README notes Linux installations may also be vulnerable. No destructive fake behavior is present; the repository is a genuine exploit PoC.
This repository contains a single Metasploit module targeting ConnectWise ScreenConnect servers vulnerable to CVE-2024-1709 (authentication bypass) and CVE-2024-1708 (path traversal). The exploit allows an unauthenticated attacker to create a new administrator account and upload a malicious extension, resulting in remote code execution as SYSTEM/root. The module supports Windows, Linux, and Unix targets running ScreenConnect version 23.9.7 and below. The attack is performed over HTTP(S) (default port 8040) and does not require prior authentication. The module is weaponized, allowing the operator to select from a variety of Metasploit payloads (e.g., Meterpreter, reverse shell). Key endpoints used include '/Host.aspx' for fingerprinting, '/App_Extensions/<payload_ashx>' for payload delivery, and '/Services/ExtensionService.ashx/UninstallExtension' for cleanup. The code is well-structured, leverages Metasploit's HttpClient and FileDropper mixins, and provides options for custom usernames and passwords for the created admin account.
