SoftGuard SNMP Network Management Extension File Download (CVE-2022-31202)

Application Details

SoftGuard is a network management extension which collects inventory, analysis, and debugging data of devices and networks.


SoftGuard Web could allow a remote authenticated attacker to obtain sensitive information, caused by insufficient validation of user-supplied input by the export function and built-in man functionality in the SNMP Network Management Extension component.


By sending a specially crafted request the attacker is able to define the complete path and the filename allowing them to read any arbitrary local file.

POST /cgi-bin/man.tcl
PAYLOAD - act=1&x=/etc/passwd&submit=Execute


By turning this into a traffic file and matching rule, we are able to detect attempts to download arbitrary files onto the system, to launch attacks.


Idappcom has created signature 8022802 along with a traffic file.
