Covide Groupware-CRM contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to a script not properly sanitizing user-supplied input to the 'User ID' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Upgrade to version 5.2 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
