Description:
unohope has discovered some vulnerabilities in yblog, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.
1) Input passed to the "q" parameter in search.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation of this vulnerability allows e.g. retrieving usernames and passwords, but requires that "magic_quotes_gpc" is disabled.
2) Input passed to the "n" parameter in user.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation of this vulnerability allows e.g. retrieving usernames and passwords, but requires that "register_globals" is enabled and that "magic_quotes_gpc" is disabled.
3) Input passed to the "q" parameter in search.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.
4) Input passed to the "n" parameter in user.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.
Successful exploitation of this vulnerability requires that "register_globals" is enabled.
5) Input passed to the "n" parameter in uss.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.
Successful exploitation of this vulnerability requires that "register_globals" is enabled and that the target user has valid user credentials.
The vulnerabilities are confirmed in version 0.2.2.2. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised.
