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.
