Loading vulnerability…
CVE-2023-24489 is a critical unauthenticated arbitrary-file-upload vulnerability in customer-managed Citrix ShareFile StorageZones Controller versions earlier than 5.11.24. The Documentum Connector upload implementation continues processing without an authenticated session and uses AES-CBC with PKCS#7 padding to validate an encrypted folder identifier. Because decryption errors are suppressed and a ciphertext with valid padding yields a non-empty result, an attacker can bypass this validation without possessing the encryption key. The upload handler sanitizes the supplied filename but fails to sanitize the upload identifier used when constructing the temporary write path, enabling directory traversal. Combining the padding-validation bypass with traversal permits an unauthenticated remote attacker to write attacker-controlled ASPX content into a writable IIS webroot location and execute it.

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.

An unauthenticated remote-code-execution vulnerability in Citrix ShareFile Storage Zones Controller. A cryptographic weakness combined with path traversal allows arbitrary file upload to the webroot, enabling an attacker to deploy a web shell and execute commands.
An unauthenticated remote code execution vulnerability in Citrix ShareFile Storage Zones Controller (Storage Center). An attacker can bypass validation of the encrypted parentid parameter using a CBC/PKCS#7 padding-valid ciphertext, then exploit an unsanitized uploadid path traversal to write an ASPX webshell into a web-accessible directory.
