Citrix ShareFile Storage Zones Controller unauthenticated file upload and RCE
CVE-2023-24489 is a critical vulnerability in customer-managed Citrix ShareFile Storage Zones Controller, affecting supported versions prior to 5.11.24. The flaw is in the Documentum Connector upload workflow, particularly upload.aspx and the underlying file handling path. According to the provided content, the application may continue processing requests without enforcing authentication when the expected session cookie is absent. In addition, an AES-CBC/PKCS#7-based encrypted parameter check can be bypassed by supplying ciphertext that decrypts to data with valid padding. The upload flow also fails to properly sanitize the uploadId parameter before using it in file path construction, enabling path traversal during file upload. Together, these issues allow an unauthenticated remote attacker to upload an arbitrary file, including a malicious ASPX web shell, to a server-controlled path and then execute it via HTTP, resulting in remote compromise of the ShareFile Storage Zones Controller.

Exploits
1 valid exploit after Mallory filtered fakes, detection scripts, and README-only repos.
This repository contains a Python exploit script (cve.py) targeting Citrix ShareFile's remote code execution vulnerability (CVE-2023-24489). The exploit works by abusing the /documentum/upload.aspx endpoint to upload a crafted ASPX webshell, which then allows arbitrary command execution on the target server. The script supports both Windows and Linux targets, generating the appropriate payload for each. It can be run in two modes: direct exploitation of a single target (--host) or mass checking a list of potential targets (--mass-check). The script is operational and provides command execution capabilities, returning the output to the attacker. The main fingerprintable endpoints are /documentum/upload.aspx (for exploitation) and /cifs/real.aspx (for retrieving command output). The repository is structured simply, with the main exploit logic in cve.py, and includes a README with usage instructions and references.
