ONEKEY Analysis Lab has uncovered a extreme command injection vulnerability within the MeteoBridge firmware, a compact system designed to attach private climate stations to public climate networks like Climate Underground.
This flaw, recognized by means of ONEKEY’s not too long ago launched bash static code evaluation on their platform, impacts variations 6.1 and under of the MeteoBridge firmware, enabling distant, unauthenticated attackers to execute arbitrary instructions with root privileges.
The vulnerability, now assigned CVE-2025-4008, has been patched in model 6.2 following a coordinated disclosure course of. With a CVSS rating of 8.7 (Excessive), the influence of this problem underscores the crucial want for sturdy firmware safety in Web-connected gadgets.
Essential Flaw Exposes Climate Station Gadgets
The vulnerability resides within the MeteoBridge net interface, particularly inside the CGI shell script accessible at /cgi-bin/template.cgi.
This endpoint processes consumer enter from the $QUERY_STRING variable with out correct sanitization, feeding it straight into an eval name a infamous vector for command injection assaults.
Consequently, malicious actors can craft HTTP requests to execute arbitrary system instructions on the system.
Making issues worse, an authentication bypass exists on account of a misconfiguration within the uhttpd server settings.
Unauthenticated Exploitation by way of Public Endpoint
Whereas sure directories like /cgi-bin are protected by primary authentication, the affected script can also be uncovered in an unprotected /public listing, permitting attackers to bypass login necessities fully.
This twin flaw implies that anybody with community entry probably even over the Web can exploit the system with out credentials.
Shodan information signifies that between 70 and 130 MeteoBridge gadgets are seen on-line at any given time, amplifying the chance of real-world exploitation regardless of the seller’s advisory cautioning in opposition to Web publicity.
Additional compounding the menace, the assault could be executed by way of a easy GET request, making it attainable to craft malicious net hyperlinks or embed exploit code in seemingly innocuous parts like
A sufferer merely must click on a hyperlink pointing to http://[target]/public/template.cgi?templatefile=$(command) to set off the exploit, enabling eventualities like distant code execution by means of social engineering.
ONEKEY demonstrated this with a proof-of-concept utilizing curl instructions, confirming that attackers can’t solely inject instructions but additionally retrieve their output within the HTTP response, offering speedy suggestions on the success of their malicious actions.
This discovery highlights the ability of ONEKEY’s automated bash static evaluation, which flagged the problem throughout a routine scan of their firmware corpus.
In line with the Report, The proactive identification of this flaw, adopted by a structured disclosure timeline involving a number of notifications to Smartbedded (the seller) and coordination with the German BSI, showcases the significance of accountable vulnerability dealing with.
Regardless of preliminary challenges, together with the deletion of a discussion board submit and account by MeteoBridge directors, persistence paid off with the discharge of a patch on Could 14, 2025, as detailed within the vendor’s advisory.
For customers, upgrading to model 6.2 is crucial, whereas organizations managing firmware should leverage automated instruments like ONEKEY’s platform to detect and mitigate such shell script vulnerabilities earlier than they change into exploitable threats within the wild.
This incident serves as a stark reminder of the hidden risks in IoT gadgets and the necessity for steady safety vigilance.
