CVE-2020-8193 is an improper access control vulnerability in Citrix ADC and Citrix Gateway versions before 13.0-58.30, 12.1-57.18, 12.0-63.21, 11.1-64.14, and 10.5-70.18, and in Citrix SD-WAN WAN-OP versions before 11.1.1a, 11.0.3d, and 10.2.7. The flaw allows unauthenticated access to certain URL endpoints that should not be reachable without proper authorization. Based on the provided content, the issue is an access-control failure affecting exposed web-accessible functionality on these appliances. The supporting material also notes observed attacker interest in Citrix appliances and password spraying against the Citrix Nitro API, indicating these systems were actively targeted in the wild during the same period.

This repository contains a Python exploit script (Citrix.py) targeting Citrix ADC (NetScaler) appliances vulnerable to CVE-2019-19781, as referenced in Citrix advisory CTX276688. The exploit leverages a Local File Inclusion (LFI) vulnerability to read arbitrary files from the target system. The script establishes a session with the device, manipulates session state, retrieves a required random value, and then issues a crafted POST request to the /rapi/filedownload endpoint to retrieve files specified by the attacker. The exploit is interactive, allowing the user to specify which files to read. The README.md provides detailed usage instructions, HTTP request/response examples, and references to external advisories and writeups. The main attack vector is network-based, requiring access to the Citrix ADC's web interface. No detection or fake code is present; the script is a functional exploit.
