Description:
Some vulnerabilities have been discovered in SimpleBlog, which can be exploited by malicious people to conduct SQL injection attacks and perform actions with escalated privileges.
1) Various scripts in the "admin" directory do not properly authenticate user requests. This can be exploited to perform certain actions with escalated privileges (e.g. to add users).
2) Input passed to the "id" parameter in admin/edit.asp and comments_get.asp is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The vulnerabilities are partially reported in version 2.3 and confirmed in version 3.0. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised and restrict access to the admin directory.
Provided and/or discovered by:
bolivar, an anonymous person, and MurderSkillz.
