Title: Entrust GetAccess File Disclosure Vulnerability
Severity: HIGH
Description:
Entrust GetAccess allows administration of individual user access rights and customer profiles on high-volume 'portal' websites.
Default shellscripts are bundled with Entrust GetAccess to provide localized help and interactivity for users. However, the sample scripts do not sufficiently validate user-supplied input.
A remote attacker can make a web request containing '../' sequences, null characters or shell metacharacters to access resources (such as arbitrary web-readable files) outside of the wwwroot directory on a vulnerable host.

The above web request must contain the following script parameters:
mode=
&draw=x
&file=x
&module=
&locale= [relative FILE/PATH] [Nullbyte/0x00] [Backslash/0x5c]
&chapter=
Sensitive information disclosed in arbitrary web-readable files may facilitate further "intelligent" attacks on the host.
