A critical vulnerability affecting wireless communication base stations from Baicells Technologies can be exploited to cause disruption in telecom networks or take complete control of data and voice traffic, according to a researcher.
Baicells Technologies is a US-based telecommunications equipment provider for 4G and 5G networks. The company says more than 100,000 of its base stations are deployed across 64 countries around the world.
Cyber offensive researcher Rustam Amin discovered that at least some of Baicells’ Nova base station products are affected by a critical command injection vulnerability that can be exploited remotely without authentication by sending specially crafted HTTP requests to the targeted device.
Exploitation of the vulnerability, tracked as CVE-2023-24508, can allow an attacker to run shell commands with root privileges and take complete control of a device, Amin told SecurityWeek.
The researcher explained that an attacker could, for instance, easily shut down a device to cause disruption. In addition, they could take full control over the traffic and phone calls going over a targeted network. A hacker could obtain information such as phone numbers, IMEI, and location data.
