Brief description:
phpwind in the realization of a placeholder for the SQL process, the code quality appears a small black point.
Detailed description:
In
phpwind/lib/utility/querybuilder.class.php
_parseStatement function within the
在 /phpwind/actions/ajax/leaveword.php
A reference at the
Line 7 line 8
$db->update(pwQuery::buildClause("UPDATE :pw_table SET leaveword=" . S::sqlEscape($atc_content) . "$sqladd WHERE pid=:pid AND tid=:tid", array($pw_posts, $pid, $tid)));
Didn't consider the$atc_content may be a placeholder
Also did not consider the pid should be a number, taken directly a string
Line: 3 1
But since the PW is replaced by the equal sign, replacing),cannot lead to very seriousSQL injectionvulnerabilities.
When submitting pid=asd, atc_content:pid case tips
Query Error: UPDATE pw_posts SET leaveword= ' 'asd' ' WHERE pid= 'asd' AND tid="
Repair solutions:
