Sewio’s Real-Time Location System (RTLS) Studio version 2.0.0 up to and including version 2.6.2 does not validate the length of RTLS report payloads during communication. This allows an attacker to send an exceedingly long payload, resulting in an out-of-bounds write to cause a denial-of-service condition or code execution.
