High
Published: Translated: NVD NIST

Summary

A vulnerability in the Cisco application-hosting framework (CAF) component of the Cisco IOx application environment allows an authenticated, remote attacker to write or modify arbitrary files in the virtual instance running on the affected device. The vulnerability is due to insufficient input validation of user-supplied application packages.

Risk Assessment

An attacker who can upload a malicious package within Cisco IOx could exploit the vulnerability to modify arbitrary files, potentially leading to unauthorized changes in the virtual instance. The impacts of a successful exploit are limited to the scope of the virtual instance and do not affect the router hosting Cisco IOx.

Recommendation

It is recommended to update to non-vulnerable versions of Cisco IOx and implement appropriate input validation mechanisms for uploaded application packages.
