CWE-1037

Processor Optimization Removal or Modification of Security-critical Code

The developer builds a security-critical protection mechanism into the software, but the processor optimizes the execution of the program such that the mechanism is removed or modified.

Architecture and Design

Optimizations built into the design of the processor can have unintended consequences during the execution of an application.

Bypass Protection Mechanism

Etkilenen güvenlik alanları: Integrity

A successful exploitation of this weakness will change the order of an application's execution and will likely be used to bypass specific protection mechanisms. This bypass can be exploited further to potentially read data that should otherwise be unaccessible.

Savunma

Nasıl önlenir ve çözülür?

  • Follow secure coding guidelines for input handling and boundary checking.
  • Enforce strict security reviews and automated static analysis (SAST) checks.

Doğrulama

Nasıl tespit edilir?

White Box

Opportunistic
In theory this weakness can be detected through the use of white box testing techniques where specifically crafted test cases are used in conjunction with debuggers to verify the order of statements being executed.

Although the mentioned detection method is theoretically possible, the use of speculative execution is a preferred way of increasing processor performance. The reality is that a large number of statements are executed out of order, and determining if any of them break an access control property would be extremely opportunistic.
