Full Disclosure: Arbitrary Code Execution in LedgerSMB CVE-2006-5872

CVE-2006-5872 (filed against SQL-Ledger) also affects LedgerSMB. This
was first fixed in LedgerSMB 1.1.5 but due to a number of unrelated
bugs, we recommend upgrading to 1.1.7. SQL-Ledger fixed the problem in
2.6.21.

This occurs due to the improper handling of input handling in the
redirect function which also allows the user to specify a file with
arguments to be run via Perl. However, since one can specify -e as the
script (making the command line perl -e …) one can specify whatever
code to execute one would like.

The following link demonstrates the vulnerability.
