CVE-2023-37567 describes a command injection vulnerability affecting several models of ELECOM and LOGITEC wireless LAN routers. This vulnerability allows a remote unauthenticated attacker to execute arbitrary commands by crafting a specific request to the web management interface on a certain port.
With a CVSS score of 9.8, this vulnerability is classified as critical. The potential impact is severe, as it could lead to unauthorized access and manipulation of the affected devices. Given the nature of the flaw, attackers can exploit it without requiring any privileges or user interaction.
The affected router models include WRC-1167GHBK3-A v1.24 and earlier, WRC-F1167ACF2 (all versions), WRC-600GHBK-A (all versions), WRC-733FEBK2-A (all versions), WRC-1467GHBK-A (all versions), WRC-1900GHBK-A (all versions), and LAN-W301NR (all versions).
Organizations should prioritize patching immediately to mitigate potential exploitation risks. The urgency is underscored by the vulnerability's high severity and the ease of exploitation.
Vulnerability Details
The command injection vulnerability in ELECOM and LOGITEC wireless LAN routers permits a remote unauthenticated attacker to send specially crafted requests to the web management page, leading to arbitrary command execution.
The CVSS score of 9.8 indicates critical severity, meaning that the vulnerability poses a significant risk to the confidentiality, integrity, and availability of the affected systems. The vulnerability is classified under CWE-77, which relates to command injection.
The vulnerability was published on July 13, 2023, and has since been modified in its status. Organizations using the affected router models should verify their firmware versions and apply necessary patches.
Technical Analysis
The root cause of this vulnerability lies in improper validation of inputs on the web management interface of the routers, allowing attackers to inject commands that the system may execute. The attack vector is network-based, requiring no physical access to the device.
The attack complexity is low, as it does not require any special conditions or privileges. This makes it particularly dangerous, as a wide range of potential attackers can exploit this flaw without needing to bypass authentication or obtain user consent.
Once exploited, the attacker could potentially access sensitive information, modify configurations, and disrupt the availability of the service, leading to broad impacts on the network.
Risk & Impact Analysis
The real-world risk associated with CVE-2023-37567 is substantial. Given the widespread use of affected ELECOM and LOGITEC routers, the potential attack surface is extensive. Attackers leveraging this vulnerability could gain complete control over the device, leading to unauthorized access to the network it protects.
The blast radius of this vulnerability is significant, as it affects multiple models and versions of routers. Organizations must assess their exposure and take immediate action to protect their environments.
Considering its CVSS score and the implications of exploitation, organizations should prioritize remediation efforts in their patch management cycles.
