Summary

The Horde_Vfs_Smb driver in Horde Virtual File System (VFS) API before version 3.0.1 contains an OS command injection vulnerability. The _escapeShellCommand() method fails to sanitize command substitution sequences, allowing authenticated attackers to inject arbitrary shell commands through user-controlled filenames.

Risk Assessment

Attackers can supply malicious filenames containing unescaped command substitution payloads through operations such as file upload, folder creation, rename, or deletion. These payloads are interpolated into a double-quoted shell context and executed via proc_open() through /bin/sh -c before smbclient runs, resulting in arbitrary command execution on the underlying system.

Recommendation

Immediately upgrade the Horde VFS library to version 3.0.1 or later, which includes a fix for this vulnerability. Additionally, consider restricting authenticated user permissions to the minimum necessary for their tasks.
