LedgerSMB is a free web-based double-entry accounting system. When a LedgerSMB database administrator has an active session in /setup.pl, an attacker can trick the admin into clicking on a link which automatically submits a request to setup.pl without the admin's consent. This request can be used to create a new user account with full application (/login.pl) privileges, leading to privilege escalation. The vulnerability is patched in versions 1.10.30 and 1.11.9.

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.

LedgerSMB does not check the origin of HTML fragments merged into the browser's DOM. By sending a specially crafted URL to an authenticated user, this flaw can be abused for remote code execution and information disclosure.

The PGObject::Util::DBAdmin module before 0.120.0 for Perl, as used in LedgerSMB through 1.5.x, insufficiently sanitizes or escapes variable values used as part of shell command execution, resulting in shell code injection via the create(), run_file(), backup(), or restore() function. The vulnerability allows unauthorized users to execute code with the same privileges as the running application.
