SQL-Ledger and LedgerSMB am.pl directory traversal
| sqlledger-ledgersmb-am-directory-traversal (33306) |  Medium Risk |
Description:
SQL-Ledger and LedgerSMB could allow a remote attacker to traverse directories on the system. An attacker could send a specially-crafted URL request to the am.pl script containing "dot dot" sequences (/../) in the login parameter and appended with NULL (%00) characters to bypass authentication and run executables on the system.

(dot dot) sequence and trailing NULL (%00) in the login parameter. NOTE: this issue was reportedly addressed in SQL-Ledger 2.6.27, however third-party researchers claim that the file is still executed even though an error is generated.
