alpine 3.6
access weakness #298


Weakness Breakdown


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.

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