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:

quagga/src/quagga-1.2.4/tests/main.c

Context:

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

-A, --vty_addr     Set vty's bind address\n\
-P, --vty_port     Set vty's port number\n\
-v, --version      Print program version\n\
-h, --help         Display this help and exit\n\
\n\
Report bugs to %s\n", progname, ZEBRA_BUG_ADDRESS);
