Technical Details & Description:
================================
A sql injection web vulnerability has been discovered in the official PHPLIST v3.0.6 & v3.0.10 open source web-application.
The vulnerability allows an attacker to inject sql commands by usage of a vulnerable value to compromise the application dbms.
The sql injection vulnerability is located in the abo user search engine of the phplist application. Local privileged accounts
are able to inject own sql commands by usage of vulnerable findby value in the abo user search module. A successful attack requires
to manipulate a GET method request with vulnerable findby value. The injection is a basic order by sql injection that allows to
compromise the web-application.
The security risk of the sql injection vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 6.1.
Exploitation of the application-side web vulnerability requires a low privileged web-application user account and no user interaction.
Successful exploitation of the security vulnerability result in web-application and database management system compromise.
Request Method(s):
[+] GET
Vulnerable Module(s):
[+] Abonnenten suchen > Abonnenten finden > Abonnenten finden
Vulnerable Parameter(s):
[+] findby
Proof of Concept (PoC):
=======================
The sql injection web vulnerability can be exploited by remote attackers with privileged application user account and without user interaction.

Solution - Fix & Patch:
=======================
The vulnerability can be patched by a restriction of the findby parameter in the abo user search module. Encode and parse the input values to prevent sql injection attacks.
Use a prepared statement to secure the point were the app communicates with the local dbms. Disallow that php code errors becomes visible - error(0).
Security Risk:
==============
The security risk of the sql injection web vulnerability in the findby value of the abo user search module is estimated as high.
