CompTIA CAS-002 Question Answer

A developer has implemented a piece of client-side JavaScript code to sanitize a user's provided input to a web page login screen. The code ensures that only the upper case and lower case letters are entered in the username field, and that only a 6-digit PIN is entered in the password field. A security administrator is
concerned with the following web server log: - [02/Mar/2014:06:13:04] "GET /site/script.php?user=admin&pass=pass%20or %201=1 HTTP/1.1" 200 5724
Given this log, which of the following is the security administrator concerned with and which fix should be implemented by the developer?

A. The security administrator is concerned with nonprintable characters being used to gain administrative access, and the developer should strip all nonprintable characters.
B. The security administrator is concerned with XSS, and the developer should normalize Unicode characters on the browser side.
C. The security administrator is concerned with SQL injection, and the developer should implement server side input validation.
D. The security administrator is concerned that someone may log on as the administrator, and the developer should ensure strong passwords are enforced.

Answer: C

The security administrator finds unauthorized tables and records, which were not present before, on a Linux database server. The database server communicates only with one web server, which connects to the database server via an account with SELECT only privileges. Web server logs show the following: - [08/Mar/2014:10:54:04] "GET calendar.php?create%20table%20hidden HTTP/1.1" 200 5724 - [08/Mar/2014:10:54:05] "GET ../../../root/.bash_history HTTP/1.1" 200 5724 - [08/Mar/2014:10:54:04] "GET index.php?
user=<script>Create</script> HTTP/1.1" 200 5724
The security administrator also inspects the following file system locations on the database server using the command `ls -al /root'
drwxrwxrwx 11 root root 4096 Sep 28 22:45 .
drwxr-xr-x 25 root root 4096 Mar 8 09:30 ..
-rws------ 25 root root 4096 Mar 8 09:30 .bash_history -rw------- 25 root root 4096 Mar 8 09:30 .bash_history -rw------- 25 root root 4096 Mar 8 09:30 .profile
-rw------- 25 root root 4096 Mar 8 09:30 .ssh
Which of the following attacks was used to compromise the database server and what can the security administrator implement to detect such attacks in the future?
(Select TWO).

A. Privilege escalation
B. Brute force attack
C. SQL injection
D. Cross-site scripting
E. Using input validation, ensure the following characters are sanitized: <>
F. Update crontab with: find / \( -perm -4000 \) type f print0 | xargs -0 ls l |
G. Implement the following PHP directive: $clean_user_input = addslashes($user_input)
