Russ McRee has discovered some vulnerabilities in web@all, which can be exploited by malicious users to conduct SQL injection attacks and by malicious people to conduct cross-site scripting attacks.
1) Input passed via the "_sv" parameter to search.php is not properly sanitised in dat/cache_tpl/web/search.htm.php 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.
2) Input passed via various parameters to multiple files is not properly sanitised in dat/cache_tpl/web/_msg.htm.php 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.
3) Input passed e.g. via the "filename" parameter to mem/action.php (when "_lib" , "_file" , "_act" , and "category_id" are set) is not properly sanitised in lib/article/article_mem_add.php before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation of this vulnerability requires that "magic_quotes_gpc" is disabled.
The vulnerabilities are confirmed in version 1.1. Prior versions may also be affected.
Solution: Update to version 1.1.1.
Provided and/or discovered by: 1) Independently reported by Russ McRee via Secunia and Vinz.
2, 3) Russ McRee via Secunia.
