CVE-2025-34029: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Edimax Edimax EW-7438RPn Mini
An OS command injection vulnerability exists in the Edimax EW-7438RPn Mini firmware version 1.13 and prior via the syscmd.asp form handler. The /goform/formSysCmd endpoint exposes a system command interface through the sysCmd parameter. A remote authenticated attacker can submit arbitrary shell commands directly, resulting in command execution as the root user.
AI Analysis
Technical Summary
CVE-2025-34029 is a critical OS command injection vulnerability affecting the Edimax EW-7438RPn Mini wireless access point firmware version 1.13 and earlier. The vulnerability resides in the /goform/formSysCmd endpoint, specifically in the syscmd.asp form handler. This endpoint accepts a sysCmd parameter that is intended to execute system commands. However, due to improper neutralization of special elements (CWE-78), the input is not properly sanitized, allowing a remote authenticated attacker to inject arbitrary shell commands. These commands are executed with root privileges, granting full control over the device. The vulnerability requires authentication but no user interaction beyond that. The CVSS 4.0 base score is 9.4, reflecting the high impact on confidentiality, integrity, and availability, combined with low attack complexity and no user interaction. Exploitation could lead to complete device compromise, enabling attackers to manipulate network traffic, pivot into internal networks, or disrupt network services. No public exploits have been reported yet, but the severity and ease of exploitation make it a significant risk for affected environments.
Potential Impact
For European organizations, this vulnerability poses a substantial threat, especially for those using Edimax EW-7438RPn Mini devices in their network infrastructure. Compromise of these devices can lead to unauthorized access to internal networks, interception or manipulation of sensitive data, and disruption of network availability. Given the root-level command execution, attackers could deploy persistent malware, create backdoors, or launch further attacks against connected systems. This is particularly critical for sectors with stringent data protection requirements such as finance, healthcare, and critical infrastructure. Additionally, the vulnerability could be exploited to undermine network segmentation, facilitating lateral movement within corporate networks. The lack of public exploits currently offers a small window for mitigation before widespread exploitation might occur.
Mitigation Recommendations
1. Immediate firmware upgrade: Organizations should verify if Edimax has released a patched firmware version beyond 1.13 and apply it promptly. If no patch is available, consider disabling or isolating affected devices from critical network segments. 2. Access control tightening: Restrict administrative access to the device management interface to trusted IP addresses and enforce strong authentication mechanisms. 3. Network segmentation: Place vulnerable devices behind firewalls or VLANs to limit exposure and reduce the attack surface. 4. Monitor logs and network traffic for unusual command execution patterns or unexpected outbound connections originating from these devices. 5. If possible, replace affected devices with models not impacted by this vulnerability, especially in high-risk environments. 6. Implement multi-factor authentication for device management interfaces to reduce risk from compromised credentials. 7. Conduct regular vulnerability scans and penetration tests focusing on network devices to detect exploitation attempts early.
