CWE-597

Use of Wrong Operator in String Comparison

Category: VariantCVE: 3

Description

The product uses the wrong operator when comparing a string, such as using "==" when the .equals() method should be used instead.

Extended Description

In Java, using == or != to compare two strings for equality actually compares two objects for equality rather than their string values for equality. Chances are good that the two references will never be equal. While this weakness often only affects program correctness, if the equality is used for a security decision, the unintended comparison result could be leveraged to affect program security.

CVE-2022-36072

SilverwareGames.io is a social network for users to play video games online. In version 1.1.8 and prior, due to an unobvious feature of PHP, hashes generated by built-in functions and starting with the `0e` symbols were being handled as zero multiplied with the `e` number. Therefore, the hash value was equal to 0. The maintainers fixed this in version 1.1.9 by using `===` instead of `==` in comparisons where it is possible (e.g. on sign in/sign up handlers).
