InduSoft NTWebServer web service stack-based buffer overflow

Original Release date: 12 Jan 2011 | Last revised: 12 Jan 2011


InduSoft NTWebServer web service contains a stack-based buffer overflow vulnerability.


According to InduSoft's website: "InduSoft Web Studio™ is a powerful collection of automation tools that provide all the automation building blocks to develop HMIs, SCADA systems and embedded instrumentation solutions. Utilize InduSoft integrated Web technologies to take advantage of Internet/intranet connectivity." InduSoft NTWebServer runs a test web service on port 80/tcp. InduSoft NTWebServer test web service is vulnerable to a stack-based buffer overflow when more than 2048 bytes are written to the fixed-size stack buffer causing the test web service to write past the bounds of the buffer and corrupt the memory.


An attacker can cause the service to crash and may be able to execute arbitrary code.



InduSoft recommends using NTWebServer test web service only for development purposes and Microsoft IIS for production.

Restrict Access

Enable firewall rules to restrict access for port 80/tcp to only trusted sources.
