Arbitrary Code Execution in SQL-Ledger and LedgerSMB through redirects

Separate from CVE-2006-5872, there is a possibility of causing arbitrary
code execution during redirects. This requires a valid login to exploit
and was discovered and brought to the attention of both the SQL-Ledger
and LedgerSMB team in November. LedgerSMB 1.1.5 corred the problem, but
it is still not corrected in SQL-Ledger.

There is no workaround to prevent the problem except to hope that those
who are using vulnerable software can be trusted.

I will be sending a full disclosure of the problem, as well as an
unofficial patch to SQL-Ledger in a week.
