Directory Traversal in Kyocera ECOSYS M2035dn Allows Sensitive File Access

Publication date: 2026-01-13

Last updated on: 2026-01-13

Assigner: VulnCheck

Description
Kyocera Command Center RX ECOSYS M2035dn contains a directory traversal vulnerability that allows unauthenticated attackers to read sensitive system files by manipulating file paths under the /js/ path. Attackers can exploit the issue by sending requests like /js/../../../../.../etc/passwd%00.jpg (null-byte appended traversal) to access critical files such as /etc/passwd and /etc/shadow.

Executive Summary

CVE-2022-50932 is a high-severity directory traversal vulnerability in the Kyocera Command Center RX ECOSYS M2035dn printer. It allows unauthenticated attackers to read sensitive system files by manipulating file paths within the /js/ directory. Attackers exploit this by sending specially crafted requests that include directory traversal sequences combined with a null byte (e.g., /js/../../../../.../etc/passwd%00.jpg), which tricks the system into disclosing critical files such as /etc/passwd and /etc/shadow without requiring any authentication. [1, 2]

Impact Analysis

This vulnerability can have a significant impact by allowing remote, unauthenticated attackers to access sensitive system files on the affected printer. Access to files like /etc/passwd and /etc/shadow can expose user account information and hashed passwords, potentially leading to further attacks such as privilege escalation or unauthorized access to the device or network. Since no authentication or user interaction is required, the risk of exploitation is high, compromising confidentiality of the system. [1, 2]

Detection Guidance

This vulnerability can be detected by sending crafted HTTP GET requests to the affected device's /js/ path, attempting directory traversal with null byte termination to access sensitive files. For example, using curl commands: 1. curl -i http://<device-ip>/js/../../../../../../../../etc/passwd%00.jpg 2. curl -i http://<device-ip>/js/../../../../../../../../etc/shadow%00.jpg If the server responds with HTTP 200 OK and returns file contents, the device is vulnerable.
