access weakness #162

Weakness Breakdown


Definition:

An access weakness occurs when software does not properly implement permissions that could have unintended consequences if exploited by malicious actors. An example of this weakness is when a default username and password are set by the developer but do not get changed by the system administrator.

Warning code(s):

Ensure that umask is given most restrictive possible setting.

File Name:

Context:

The highlighted line of code below is the trigger point of this particular Alpine 3.6 access weakness.
