LedgerSMB does not sufficiently guard against being wrapped by other sites, making it vulnerable to 'clickjacking'. This allows an attacker to trick a targetted user to execute unintended actions.

LedgerSMB does not sufficiently HTML-encode error messages sent to the browser. By sending a specially crafted URL to an authenticated user, this flaw can be abused for remote code execution and information disclosure.

SQL injection vulnerability in the AR/AP transaction report in (1) LedgerSMB (LSMB) before 1.2.15 and (2) SQL-Ledger 2.8.17 and earlier allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors.

The CGI scripts in (1) LedgerSMB (LSMB) before 1.2.15 and (2) SQL-Ledger 2.8.17 and earlier allow remote attackers to cause a denial of service (resource exhaustion) via an HTTP POST request with a large Content-Length.

Multiple SQL injection vulnerabilities in (a) LedgerSMB 1.0.0 through 1.2.7 and (b) DWS Systems SQL-Ledger 2.x allow remote attackers to execute arbitrary SQL commands via (1) the invoice quantity field or (2) the sort field.

(1) LedgerSMB and (2) DWS Systems SQL-Ledger implement access control lists by changing the set of URLs linked from menus, which allows remote attackers to access restricted functionality via direct requests. The LedgerSMB affected versions are before 1.3.0.
