Non-exit on Failed Initialization
The product does not exit or otherwise modify its operation when security-relevant errors occur during initialization, such as when a configuration file has a format error or a hardware security module (HSM) cannot be activated, which can cause the product to execute in a less secure fashion than intended by the administrator.
The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.
Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.
The following code intends to limit certain operations to the administrator only.
If the application is unable to extract the state information - say, due to a database timeout - then the $uid variable will not be explicitly set by the programmer. This will cause $uid to be regarded as equivalent to "0" in the conditional, allowing the original user to perform administrator actions. Even if the attacker cannot directly influence the state data, unexpected errors could cause incorrect privileges to be assigned to a user just by accident.
Weaknesses in this category are related to insufficient control flow management.
This category identifies Software Fault Patterns (SFPs) within the Incorrect Exception Behavior cluster (SFP6).
Weaknesses in this category occur in behaviors that are used for initialization and breakdown.
