Elber Communications Equipment
Act Now9.8ICS-CERT ICSA-25-035-03Feb 4, 2025
Attack VectorNetwork
Auth RequiredNone
ComplexityLow
User InteractionNone needed
Summary
Elber Communications equipment contains authentication bypass vulnerabilities (CWE-288, CWE-912) affecting multiple legacy broadcast and satellite receiver products. Successful exploitation allows an attacker to gain unauthorized administrative access to affected devices. The vendor has classified all affected products as end-of-life or near end-of-life and does not plan to release security patches.
What this means
What could happen
An attacker with network access could gain administrative control of affected broadcast and satellite receiver equipment, potentially disrupting signal distribution and content delivery systems at broadcast stations and distribution facilities.
Who's at risk
Broadcast and telecommunications equipment operators who use Elber's legacy satellite receivers, broadcast platforms, and audio transport systems. This includes broadcast stations, satellite distribution networks, and cable/fiber headend facilities that rely on Signum DVB receivers, Cleber platform systems, Reble IP-ASI converters, ESE receivers, or Wayber audio STL equipment.
How it could be exploited
An attacker on the network sends a request to the device that exploits improper authentication (CWE-288) or missing security checks (CWE-912) to bypass login protections. Once authenticated, the attacker can access administrative functions to modify device configuration or behavior.
Prerequisites
- Network access to the affected device
- No valid credentials required
- Device must be reachable from attacker's network position

Remediation & Mitigation
0/4
Do now
0/2HARDENINGImplement network segmentation to isolate affected broadcast equipment from general IT networks and the internet
WORKAROUNDDeploy firewall rules to restrict network access to affected devices, allowing only trusted management sources
Schedule — requires maintenance window
0/1Patching may require device reboot — plan for process interruption
HARDENINGIf remote access to equipment is required, use a VPN connection and ensure VPN is updated to the latest version
Long-term hardening
0/1HOTFIXPlan replacement or upgrade of affected Elber equipment to supported products, as vendor will not patch these end-of-life devices
