Alexander Klink has reported some vulnerabilities and weaknesses in DropAFew, which can be exploited by malicious users to conduct SQL injection attacks, disclose potentially sensitive information and bypass certain security restrictions.
1) Input passed to the "id" parameter in search.php and search-pda.php (when "action" is set to "del") is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL Code.
2) The editlogcal.php script does not correctly check the "id" parameter during authorisation. This can be exploited to disclose the calorie logs of other users.
3) It's possible to add links to the public link pages of other users via links.php, which cannot be removed by the user. This can be exploited to spam the website.
The vulnerabilities are reported in versions prior to 0.2.1.
Solution: Update to version 0.2.1.
