An issue was discovered in phpLiteAdmin 1.9.5 through 1.9.7.1. Due to loose comparison with == instead of === in classes/Authorization.php for the user-provided login password, it is possible to login with a simpler password if the password has the form of a power in scientific notation (like 2e2 for 200 or 0e1234 for 0). This is possible because, in the loose comparison case, PHP interprets the string as a number in scientific notation, and thus converts it to a number. After that, the comparison with == casts the user input (e.g., the string 200 or 0) to a number, too. Hence the attacker can login with just a 0 or a simple number he has to brute force. Strong comparison with === prevents the cast into numbers.
