Advisory Details:
High-Tech Bridge Security Research Lab discovered SQL injection vulnerabili=
ty in Symphony, which can be exploited to alter SQL requests to database of=
the vulnerable application.
1) SQL Injection in Symphony: CVE-2013-2559
The vulnerability exists due to insufficient filtration of "sort" HTTP GET =
parameter passed via "/symphony/system/authors/" URL to "/index.php" script=
=2E A remote authenticated administrator can execute arbitrary SQL commands=
in the application's database.
Depending on database and system configuration, this PoC (Proof of Concept)=
code will create "/var/www/file.txt" file, containing users account infor=
mation (logins, hashed passwords, etc.) from the "authors" table:
http://[host]/symphony/system/authors/?order=3Dasc&sort=3Did%20INTO%20OUTFI=
LE%20%27/var/www/file.txt%27%20--%20
This vulnerability could also be exploited by a remote non-authenticated at=
tacker via CSRF vector, since the application is prone to Cross-Site Reques=
t Forgery (CSRF) attacks. In order to do so an attacker should trick the lo=
gged-in administrator to visit a web page with CSRF exploit:
<img src=3D"http://[host]/symphony/system/authors/?order=3Dasc&sort=3Did%20=
INTO%20OUTFILE%20%27/var/www/file.txt%27%20--%20">
