Details
A vulnerability was found in Sub-IoT Stack up to 0.4.x. It has been declared as critical. Affected by this vulnerability is an unknown function of the component DASH 7 Alliance Protocol Handler. The manipulation with an unknown input leads to a out-of-bounds write vulnerability. The CWE definition for the vulnerability is CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:
The Sub-IoT implementation of the DASH 7 Alliance protocol has a vulnerability that can lead to an out-of-bounds write prior to implementation version 0.5.0. If the protocol has been compiled using default settings, this will only grant the attacker access to allocated but unused memory. However, if it was configured using non-default settings, there is the possibility that exploiting this vulnerability could lead to system crashes and remote code execution.
