i'm going to i know that many of you know what's a comment section back right okay for those who don't have the graduation that watch commands actions are attacked in windsor goal is the execution of arbitrary commands on a host operating system is possible when an application let's say what this application passes are safe you should suffer bonita such a small cookies etc this except to the system self and i reflect note here that the effective supply the braking system the ones after ages once our visual executive opposite renovations of our abilities of the vermin of education so the mean target commendation apps is later the cufflinks or the main reason for that is because
for my detection attacks are very extensive and then as well as programs effect on let's see what causes calm attitude of anything the main reason that application is vulnerable my injection attacks with using correct or complete lack of intent of validation for example the following piece of code gets an IP address through the gate idea parameter and after that thing on here is executed over the echo by IP address and a result of the execution music in the street as you can see here there is nothing into the validation which gives traffic shaman field separator let's say the same comparator and after that another pitch the cutter pls come on both of them pls from one and the think
of one he executed be one after the other exactly like the following systems right so cute operations two main categories of commands it contracts whereas in five the first one includes results based organization in which the marginal application just outputs lives off of insects come on in the attractive can today confirm if the comment section succeeds before and of course the injection yourselves are being second have been going to use blind commands actions in which the vulnerable application just does no doubt java project for one end even if the attack and injects an arbitrary c'mon to live under patient they're just window the shop in the screen so conjectures results with this let's see this this
are ducks in detail so the first one is exactly the same example as previously mentioned is the photographer and I thought oh sorry someone who maybe understand separator property come on in both execution starts going to be let's take a look at the blind case as you can see here there is not any echo at the start in the beginning of the flight the vulnerable part is the same so if some records just the IP address or some and I gathers disqualify between two survivor and then other after one in both cases the execution results will be no division right so in order for sealing we have to be blind first if you thought I'd like to eat so you
completely blinded me is the thai place like three which is based on time delays the attacker can resume there's architect go on him firstly decide if the application is valid up to 10 times blind comment section or not for example this payload this payload is a new twist video around you selected sick character string is echo anything for half of that swing is found to be six then slips for one second then the length of the output c'mon determine exactly the same way as previously mentioned here exactly the same way though and finally here authentic so on is exporting right exactly like in the strain gauge drivers the contribution is not a computing language it's a similar ah this
technique is the five basic black which is based on the fact which claims that if it were not able to finish also in solution directly to the terminal application and we can write them to a file in which service territory which is right on route or access new buyers right so I know that this is a pretty straightforward way in order to the club blind commentary here an undetected this fine right problem here is that was the winner with a range of territories are no right we can use the power technology RTP etc introduc to store a file with the output of inject common problem here is that we cannot predict flash located in to these different
directories through the web application because you take the blackness of the V so I not like a 13 detection and you another community the cake at my place the creek will develop and implement design implementing this technique applies the file basically in order to store the result of the injection into three territories in combination with the time base technique so in that way the contents of the files which are located in to this temporal directories we extracted terms of the temperature right so the function how many of you know what is the going to me comics is is a short for commands an exploiter is a chakra tool that can be used in order to find an explosive confrontation
clause is available at github as written in python is a cross-platform app is it an open source and licensed under the GPL version free if you want to get the latest version of comics you can use official repository or if you are using one of the following penetration testing clinic distributions I can give the official package monitored north winds over but they would like to note here that comes comes pre-installed in comics or if you're using one of the following penetration testing frameworks and widths Comics comes as a backing you can give the corresponding option in order to update on stone oak a comic support medics radiation techniques regarding results based on transactions the classic is our
base technique is supporting this technically based on just the execution results output don't support dynamic evaluation technique again the eval basically this technique is based on the vast execution results but except for a result also also the preg replace the user the insert yourself place and Craig mass ejections are also support regarding blank comment sections of course the time base Blanco mantiger it supportive half day five days cellulite for the combination of these techniques the ten five days ok I would like to note that all inscribe the expectation techniques provide many a variation on a paper with which are specially adjacent to the target book or target host let's say for unix targets the attack vectors
are placed in a singly over a combination of pasture land and for windows target data collectors are based on a similar combination of CMT and or a person dot exact amount in order to reduce false positives and regarding a subspace transaction and only generated 6 characters 3 is 3 times in combination with a result of a mathematical relation of travel you selected numbers something like this payload from this data we must take as bad as I response the union of these drinks which combined with the result of the math math calculation like this one regarding Blanco man's actions evening the problem here is the high probability of false positive you do not take requests so the average response
time of the target caution is calculated and also a time relative of course to identify these youth disability sconce type is adding to the default delay time which is used in order to perform time relative attacks such as type based and temp I great product and the time relative first positive identifier which detects unexpected time delays a personal request uses statistical analysis in order to detect the extended beyond our state requests so let's see some basic functionality and for xtp cheddars wherein provide first of all out of its visitors for example user agent prefer cookie challenge for excess each other something like treating here or we can perform pets for commands action against the XP headers here is an example and as
you can see here that there is a commendation attack through the usual editing and it's because here is the payload an inner part of the level option is greater or equal to 22 then automatically test comics test the cookie values and if the level option is equal to three then automatically tests usual a temperate and read write in order to marry target for we are able to use the emulation options these options we can retrieve custom user name card is a thing can't force them back to take if current user name has privileges or administrative agencies we can retrieve system information such as operating system hardware platform etc you can retrieve system users please assistant user
privileges possible causes the organization here is that this self I must be readable by the Cartesian and if we if we are against a window started we can retrieve the power cells version number and if someone fix all these lives together just national option the result will be similar to this figure another operating system cell through that same we're having to bypass started first class limitations there could be restrictions of last four months let's say the card DFO etc at this moment only if item eternity is we supported on every described technique but my future plan is somewhere peaceful parenting group etc our brakes themselves here is the alternate operating system service Python and African see here the payload
custard is Python coming today me to bypass our food security default attempt to this rule blocks the pipe symbol commercial situations parameter expansions and what is double kicked FCC which as the author claims are often used in order to perform injection attacks but as you can see here the payload has properly transformed into google in this form in order to bypass much security is a block attained i believe in love cells that's why I from supports next reversals and it cut without their cut it ourselves for more please take a look at recent example with bait in with several this case scenarios are supportive we can write or upload our own websites on target through the file access options
we can upload our own create witness after the shadow no we take a look at the upload search with phase one and here are some sense in action here's the net cut yourself here design it be terminal diversions leadership for Windows Linux meterpreter reversion through the our meetin's Commission's also mantra which means that in order to agree reveals or comics and what a tip at war needs we are able to develop it and easily import our own modules from work please by default the three main modules are supported the icing exfiltration watching the DNS occupational and of course a source of protein and here's a series of module in action in order to evaluate comics I many vulnerable web
applications the last one is the official comics test then it's accused many vulnerable a big education into commands each other apps I don't have time to say them
here's the consistent
i will put the URL into comics i'm going to introduce an option in order to when we're at the 34th opening the current user and system
give instructions the payload here here today I should go out there soon
we can use the option reverse this piece MSP
here interpreter
so thinking about the case
in order to see bagels here the tangles and this is this is the payload not permit application I'm going to execute regular one retweet five characters and trying to export the result
dry the 58 here
k visitors out
how we good
you know
the quickest and flashing
and as you can see here the level is trained in order to perform tests for
tecnica same with each other
this is
bye three
ok
bye
this is 44 b school
if you have any issue you can open it up freaky thumb
12
yes or you can specify how you want a certain person target us so do you like all the different values pie hole they give you some heuristics in order to understand the target hood if it doesn't it tries to cost you it's managed and if it's not it not proceed with the exploitation if you not specify computers yes for headers for sale where I ill talking like that is for web apps
you
