Lifecycle Timeline
1DescriptionNVD
In Weidmueller Industrial WLAN devices in multiple versions an exploitable command injection vulnerability exists in the hostname functionality. A specially crafted entry to network configuration information can cause execution of arbitrary system commands, resulting in full control of the device. An attacker can send various requests while authenticated as a high privilege user to trigger this vulnerability.
AnalysisAI
In Weidmueller Industrial WLAN devices in multiple versions an exploitable command injection vulnerability exists in the hostname functionality. Rated high severity (CVSS 7.2), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. In Weidmueller Industrial WLAN devices in multiple versions an exploitable command injection vulnerability exists in the hostname functionality. A specially crafted entry to network configuration information can cause execution of arbitrary system commands, resulting in full control of the device. An attacker can send various requests while authenticated as a high privilege user to trigger this vulnerability. Affected products include: Weidmueller Ie-Wl-Bl-Ap-Cl-Eu Firmware, Weidmueller Ie-Wlt-Bl-Ap-Cl-Eu Firmware, Weidmueller Ie-Wl-Bl-Ap-Cl-Us Firmware, Weidmueller Ie-Wlt-Bl-Ap-Cl-Us Firmware, Weidmueller Ie-Wl-Vl-Ap-Br-Cl-Eu Firmware.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
