Cisco ISR800/CGR1000/IC3000/IE4000/IOS XE/IR510 IOx Application path traversal

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as critical has been found in Cisco ISR800, CGR1000, IC3000, IE4000, IOS XE and IR510 (Router Operating System). This affects some unknown processing of the component IOx Application Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability.

The weakness was shared 04/15/2022 as cisco-sa-iox-yuXQ6hFj. The advisory is shared at tools.cisco.com. This vulnerability is uniquely identified as CVE-2022-20725 since 11/02/2021. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available.
