Unspecified vulnerability in admin.pl in SQL-Ledger before 2.6.26 and LedgerSMB before 1.1.9 allows remote attackers to bypass authentication via unknown vectors that prevents a password check from occurring.
The redirect function in Form.pm for (1) LedgerSMB before 1.1.5 and (2) SQL-Ledger allows remote authenticated users to execute arbitrary code via redirects, related to callbacks, a different issue than CVE-2006-5872.
SQL-Ledger 2.4.4 through 2.6.17 authenticates users by verifying that the value of the sql-ledger-[username] cookie matches the value of the sessionid parameter, which allows remote attackers to gain access as any logged-in user by setting the cookie and the parameter to the same value.
