CWE-582: Array Declared Public, Final, and Static
The product declares an array public, final, and static, which is not sufficient to prevent the array's contents from being modified.
How it's found
Array Declared Public, Final, and Static is a specific, narrowly defined instance of a broader pattern. Testers confirm it with targeted code review and a proof-of-concept input that exercises the exact code path this weakness describes.
Because arrays are mutable objects, the final constraint requires that the array object itself be assigned only once, but makes no guarantees about the values of the array elements. Since the array is public, a malicious program can change the values stored in the array. As such, in most cases an array declared public, final and static is a bug.
Consequences
- Modify Application Data
Mitigations
- Implementation: In most situations the array should be made private.
