SQL injection vulnerability in functions/functions_filters.asp in Web Wiz Forums before 8.05a (MySQL version) does not properly filter certain characters in SQL commands, which allows remote attackers to execute arbitrary SQL commands via \"' (backslash double-quote quote) sequences, which are collapsed into \'', as demonstrated via the name parameter to forum/pop_up_member_search.asp.

post_message_form.asp in Web Wiz Forums 6.34 through 7.5, when quote mode is used, allows remote attackers to read or write to private forums by modifying the FID (forum ID) parameter.
