What is CVE-2025-34098?

A path traversal vulnerability has been identified in Riverbed SteelHead VCX appliances, specifically in version 9.6.0a. This issue arises from insufficient input validation in the log filtering functionality accessible through the management web interface. An authenticated attacker can exploit this vulnerability by submitting specially crafted filter expressions to the log_filter endpoint using the filterStr parameter. The backend parser processes this input in a manner that allows execution of file expansion syntax, enabling the potential retrieval of arbitrary system files through the log viewing interface.
