A critical vulnerability has been found in oil tank monitoring devices from Tecson/GOK, but the vendor has released a patch and points out that there are less than 1,000 devices that could be affected.
Tecson is a Germany-based manufacturer of tank measurement systems, including oil tank displays, level probes, and remote monitoring products.
Security researcher Maxim Rupp discovered that some Tecson devices are affected by a vulnerability that allows an attacker to access a web-based configuration interface without needing appropriate credentials.
