http://secunia.com/advisories/31843/

CRITICAL:
Less critical

IMPACT:
Manipulation of data, DoS

WHERE:
>From remote

SOFTWARE:
LedgerSMB 1.x
http://secunia.com/advisories/product/11926/

DESCRIPTION:
Some vulnerabilities have been reported in LedgerSMB, which can be
exploited by malicious users to conduct SQL injection attacks and
malicious people to cause a DoS (Denial of Service).

1) Certain CGI scripts accept POST requests up to the length
specified in the "Content-Length" header. This can be exploited to
e.g. cause a DoS by exhausting the system resources via large POST
request.

2) Input passed to an unspecified parameter in the AR/AP Transactions
Report is not properly sanitised before being used in SQL queries.
This can be exploited by malicious users to manipulate SQL queries by
injecting arbitrary SQL code.

Successful exploitation of this vulnerability requires valid user
credentials.

SOLUTION:
Update to version 1.2.16.
