|

This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.0
|
||||
and 7.53. By sending a CGI request with a specially OvOSLocale cookie to Toolbar.exe, an
|
||||
attacker may be able to execute arbitrary code. Please note that this module only works
|
||||
against a specific build (ie. NNM 7.53_01195)
