Possible Fixes: The usage of htmlspeacialchars(), mysql_escape_string(), mysql_real_escape_string() and other functions for input
validation before passing user input to the mysql database, or before echoing data on the screen, would solve these problems.

Diabolic Crab,

The title and text of this advisory suggest SQL injection, but I don't
see any any clear examples that demonstrate this.

A modified Query parameter to the search function is given, and the
parameter starts with the "'" character - which might *suggest* SQL
injection - but the resulting error message suggests that it's using
the input for some array operations, which could be the fairly common
"bad data type" problem that leads to full path disclosure on PHP
applications. Indeed there might be other invalid characters that
could trigger the same problem (I don't know; I don't have ArticleLive
available to test).

Could you provide more specific examples or otherwise clarify the
problem?


Thanks,
Steve
