Description

Non-final public fields should be avoided, if possible, as the code is easily tamperable.

Consequences

  • Integrity: The object could potentially be tampered with.
  • Confidentiality: The object could potentially allow the object to be read.

Exposure period

  • Implementation: This flaw is a simple logic issue, introduced entirely at implementation time.

Platform

  • Languages: Java, C++
  • Operating platforms: Any

Required resources

Any

Severity

Medium

Likelihood of exploit

High


If a field is non-final and public, it can be changed once their value is set by any function which has access to the class which contains the field.


Risk Factors

TBD

Examples

In C++:

public int password r = 45;

In Java:

public String r = new String("My Password");

Now this field is readable from any function and can be changed by any function.
