OS Command Injection in Restricted Command

The affected product permits OS command injection through improperly restricted commands, potentially allowing attackers to execute arbitrary code.

An issue was discovered in Moxa EDR-810 Industrial Secure Router. By accessing a specific uniform resource locator (URL) on the web server, a malicious user is able to access configuration and log files (PRIVILEGE ESCALATION).

Web Server Buffer Overflow Vulnerability

A vulnerability has been identified in the EDR-810, EDR-G902, and EDR-G903 Series, making them vulnerable to the denial-of-service vulnerability. This vulnerability stems from insufficient input validation in the URI, potentially enabling malicious users to trigger the device reboot.

Second Order Command-injection Vulnerability in the Certificate-generation Function

TN-4900 Series firmware versions v1.2.4 and prior and TN-5900 Series firmware versions v3.3 and prior are vulnerable to the command-injection vulnerability. This vulnerability stems from insufficient input validation in the certificate-generation function, which could potentially allow malicious users to execute remote code on affected devices.

Second Order Command-injection Vulnerability in the Key-generation Function

TN-4900 Series firmware versions v1.2.4 and prior and TN-5900 Series firmware versions v3.3 and prior are vulnerable to the command injection vulnerability. This vulnerability stems from insufficient input validation in the key-generation function, which could potentially allow malicious users to execute remote code on affected devices.

Command-injection Vulnerability in Certificate Management

TN-4900 Series firmware versions v1.2.4 and prior and TN-5900 Series firmware versions v3.3 and prior are vulnerable to the command injection vulnerability. This vulnerability stems from inadequate input validation in the certificate management function, which could potentially allow malicious users to execute remote code on affected devices.

Certain Moxa Inc products are affected by an improper restriction of operations in EDR-G903 Series Firmware Version 5.5 or lower, EDR-G902 Series Firmware Version 5.5 or lower, and EDR-810 Series Firmware Version 5.6 or lower. Crafted requests sent to the device may allow remote arbitrary code execution.

Moxa EDR 810, all versions 5.1 and prior, allows an authenticated attacker to abuse the ping feature to execute unauthorized commands on the router, which may allow an attacker to perform remote code execution.

Moxa EDR 810, all versions 5.1 and prior, allows an unauthenticated attacker to be able to retrieve some log files from the device, which may allow sensitive information disclosure. Log files must have previously been exported by a legitimate user.

A command injection vulnerability in the web server functionality of Moxa EDR-810 V4.2 build 18041013 allows remote attackers to execute arbitrary OS commands with root privilege via the caname parameter to the /xml/net_WebCADELETEGetValue URI.

Exploitable denial of service vulnerabilities exists in the Service Agent functionality of Moxa EDR-810 V4.1 build 17030317. A specially crafted packet can cause a denial of service. An attacker can send a large packet to 4001/tcp to trigger this vulnerability.
