Description:
Some vulnerabilities have been reported in ar-blog, which can be exploited by malicious people to conduct cross-site scripting, script insertion, and SQL injection attacks, and bypass certain security restrictions.
1) Input passed when adding a comment isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious comment is viewed.
2) An error caused due to an insecure authentication process can be exploited to bypass the authentication process and access the administration section by defining certain cookie parameters.
3) Input passed to the "month" and "year" parameters in index.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Examples:
http://[victim]/index.php?page=showtopis&month=[code]&year=1426&all=9
http://[victim]/index.php?page=showtopis&month=9&year=[code]&all=9
4) Input passed to the "id" parameter in print.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
5) Input passed to the "count" parameter in index.php isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Example:
http://[victim]/index.php?page=gb&count=[code]
The vulnerabilities have been reported in version 5.2. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised and that administrators are properly authenticated.
