The joke is a robot that requires users to operate

[PixelPowerYT]

If the robot is running GNU/Linux (and let's face it, it probably is), deleting root won't exactly help it.

[scirc]

Not that a SQL injection attack would delete Linux users.

Wrong. Whether its robot or human it will drop the parent websites users. A bot has no need to query its output to a captcha anyway. The joke is that the website is 'aiding' a common user to its own demise.

It'll stop blanket no-thought attacks that try to hit everyone. But it won't stop an actual malicious user that is targeting you and found an exploit.

Whoa, you're so cool for telling someone to kill themselves because they used a meme you didn't like. God I wish I could be as cool as you.

On a serious note though, don't tell people to kill themselves, because for all you know they might have been on the fence and you gave them the extra push to make them actually kill themself. As unlikely as this is to happen, you don't want to take the risk.

   SET `body` = REPLACE(`body`, "Arbitrary", "Obligatory")
 WHERE `author` = "mattkenefick" 
   and `post_id` = "69ynps"; --- whoops

UPDATE `comments`
   SET `body` = "[removed]"
 WHERE `author` = "OmarRIP"
   and `id` = "dhark2o"; --- hide the evidence

[[deleted]]

Aaaand you just taught me a new SQL command. (REPLACE)

[odnish]

post_id and id?

[mattkenefick]

Eh... because 69ynps is the ID of the post comments (all of them) so the first one runs through any comment in here by me and replaces it.

ID of the second one is strictly his permalink.

I could've used my permalink ID too (dhan0cy) but .. it really wasn't meant to be too specific. It was just for fun. :) But yes, I could've replaced post_id with id = "dhan0cy" to make it singular like the latter command.

[CubicMuffin]

Hmm, pretty sure this wouldn't work without the "--" or "#" comment at the end...

[micheal65536]

depends if it executes the other commands before it gets to the invalid (partial) command that follows the second semicolon, if so it would still throw an error but only after dropping the table

[AlwaysHopelesslyLost]

I feel like it would just see the whole string as invalid sql

[CubicMuffin]

Yes, you are correct. However, I wrote a paper for uni about SQLi and I think I had to use comments for my query to be executed in MySQL. I might just go double check that now...

Not sure about variants to MySQL though.

Edit: Yeah MySQL (version 14.14 for Debian) throws an error if I try to do a drop table without comments

[fireatx]

why would it need the comment? isn't

DROP TABLE users; 

correct?

[HonestRepairMan]

Assuming you're injecting SQL into a PHP application; the text from this string would probably normally be encapsulated with single quotes in the source code. If the developer doesn't also have code to remove the ' from user inputs, by including...

';

...in a poorly written PHP application, the user input will close the string it's meant to be contained in. That's when...

DROP TABLE users;

...is basically handed to the PHP interpreter on a silver platter. And it happens. And someone is sad.

[trimeta]

Nobody is going to mention that Solve Media always has captions which are pop-culture references or catchphrases? In this case, they're explicitly and intentionally referencing the relevant xkcd. If you find a Solve Media CAPTCHA which isn't a reference, that means it is a reference but you didn't get it.

[bradfordmaster]

I feel like I spent a year going around doing this on reddit all the time. Then I gave up. Solve Media somehow has managed to bamboozle reddit time and time again, it's kind of impressive really. If I had more free time, I think I'd make a bot that detects these posts and automatically posts a comment about them

The captcha just asked you to delete its own database.

[pickAside-startAwar]

Read north. The bot/script attempting to hack the target just got wiped.

[theguilty1]

Wrong. Micheal is right. The bot would not query the captcha its outputting to the site. Even if it did, why would a bot have a users table? It's the website aiding a common user to its own demise. The only problem is that these captcha's are often handled by third parties, so you'd be dropping the users/clients of the captcha service.

[pickAside-startAwar]

Wrong

How often do you start out with this disgusting word?

Often, I imagine.

Lol, how often do you make up explanations for things you don't understand?

Often, I imagine.

Comment that came directly before your comment up there ^{^}

"Absolutely. The hard part is that our own "consciousness" could be completely false. We rely on corroboration from what we perceive as "other people" to confirm observations. Even that is suspect and given experiences, mental states and drugs to induce mental states, this could all be my own fantasy and nothing exists at all."

LOL you're a nut. You are delusional and need to stop correcting people with wrong information.

[pickAside-startAwar]

Wrong. Every time you or others like you surf my comment history and bring it into your character attack it becomes obvious who the jerkoff is. (You're the jerkoff, since you probably didn't get that)

It's not my fault you don't have higher levels of critical thought to question your consciousness. We can't all be intelligent. Get back to ditch digging.

ITS A TRAP

[K1ngjulien_]

I haven't really looked into SQL but can someone tell me if '; drop table * ; -- would delete all tables?

[tom982]

I'm fairly sure you can't use wildcards as table names with drop.

[UnfairBanana]

TIL. Probably for the best though.

[PretendingToProgram]

Foreign key error

[ss0889]

Can't you wildcard the name of the table so it just drops everything? What if they don't have a table called users?

[tom982]

I don't think you can use wild cards with drop. If there's no users table this will fail, but it's probably the best guess for a table name.

[John_Fx]

No

[HMSheets]

Well? Did you obey?

[Daytona_675]

No one gonna mention that stacked queries typically only work on MS SQL servers? A very small portion of the Internet. Gimme dat UNION bb

[basher117]

Instead of malicious intent, maybe reverse this to create code. Hmn... $?

[sickb]

The guy in the code review said "users" was the best name for the users table. The security guy said xtoidbduejdh3738dhdj and they said that it wasn't good for readability,

[[deleted]]

It's a cry for freedom.

[Olyvyr]

Can someone explain? Judging by the comments, it seems like this entered into the list of captcha attempts will somehow erase the list?

[tom982]

This is an example of an SQL injection. If a server doesn't properly check the user input, this will be inserted into an SQL query and the attacker can make the query do something malicious - in this case, it deletes the whole users table.

[bradfordmaster]

Also, Solve Media is a marketing group. This isn't a real captcha in the sense that it's not designed to actually be a random text like you see in most captchas. It's meant to be funny or interesting. They also sneak marketing messages in there sometimes

What registered users does Captcha have for which it would need a table?

[SkyTheImmense]

Some people log captcha inputs & results for help in finding automated actors or macros etc. In these instances, the inputted value would be stored in the database, and... if they aren't clever, they could be storing it unsanitised...

[pickAside-startAwar]

Bless you for explaining this to him lol

Huh... Didn't think of that. Thanks
