Some people might get off on that kind of culture. But this story makes me glad I don’t work there for some reason.

Conversely I would prefer to work in a place like that. Professionalism at scale isn’t achievable by tolerating idiotic behaviour and being nice to everyone no matter how dangerously stupid they are being. There is a point where someone has to put their foot down and demand things be done properly, otherwise the inevitable consequence is a giant mess leading to disaster. You might be used to small startup teams with…

>things be done properly

Now if only we could all agree how that looks exactly

``` TypeError: Cannot read properties of null (reading 'C') at Ccf ( https://docs.google.com/static/document/client/js/157553674-... ) at Bcf ( https://docs.google.com/static/document/client/js/157553674-... ) ``` Has something to do with grammar. The document does not fail when `Show grammar suggestion` is turned off.

Presumably people will start running having all sorts of fun fuzzing Google Docs now that they know that it’s not an infallible, opaque product…

Any web app pentesters here willing throw in their 2c? Could this offer insights into the way data is parsed in the backend, or might result in something more interesting than a crash?

What a great story nevertheless.

It helped me empathize with young engineers dealing with their first high responsibility bug. About 4 years ago, I was managing a guy right out of school who pushed a minor bug that broke real-time risk calculations for a major multinational financial institution in the middle of the European trading day, prior to the NYC open, and people were yelling over email that they were trading blind. Someone had committed an…

I have to say you tell good stories about how wonderful you are.

Once a customer was able to destroy an old ES cluster because they copy pasted some text from a PDF into a search box ... that text got sent directly to the ES cluster without much escaping ... there were lots of "*" in there. The query complexity exploded, ES ran out of memory, and the index got corrupted and I don't remember why, it could not recover. We had to re-index all the data. Lots of fun. Lesson learned: pr…

Yup seen that in a few online "stores" or companies where they use SOLR or ES. Putting in '' will make boxes explode* (ok not really).

What is twice is bad as that the worst of these, fail (at least to my eye) on two fronts.

1) Allowing SINGLE character searches. I.e No min query-length.

2) Not escaping querying - lucene(solr/es) syntax.

You can sometimes see the front-facing "html/js/api" is just a thin layer over ES/SOLR.(Which is not bad by itself) it's when you don't know the limitations or what sort of queries are x100 harder to do than orders.

How about "Whereas", "Insofaras", "Notwithstanding", "Thetruthofthematter", or "Despiteallobjections"? Didn't try them, but these were "reserved words" in Go (actually an easter egg) until 2017 ( https://stackoverflow.com/questions/2489803/notwithstanding-... ).

This is the strangest parsing fact I've learned since PHP having a token named T_PAAMAYIM_NEKUDOTAYIM. (Because the parser was developed in Israel.) https://stackoverflow.com/questions/592322/php-expects-t-paa...

Widely known because the token names were surfaced to users in error messages, so some common syntax mistakes would produce deeply unhelpful "Unexpected T_PAAMAYIM_NEKUDOTAYIM" errors. Hopefully they eventually did something about it, but it was like that for years and was one of the many things that put me off PHP for life.

Typing worked for me. You have to refresh.

Refreshing was the key. Just typing it in does nothing, but refreshing or opening a saved document from your documents in docs with the text in it already leads to the crash.

Does not work for me in Google Docs, no matter if copied, or reloaded, refreshed etc. Perhaps they fixed it already.

Years ago in school, maybe about 1992 or so, I managed to make xdm (X Display Manager) crash and dump me a root window by simply holding down a key until the buffer ran out. I remember wondering how anybody didn't discover this before me. Similar behavior with the university phone system (repeatedly pressing '0') eventually dropped me an outside line that I didn't have to pay for (yes, for you young folks, we used to…

I seem to remember that a few years ago some versions of either TouchWiz or Android, that you could overflow into unlocking the phone. The number required was pretty high, but you could get to it by copy pasting an already typed (In the emergeny dialer) number for a while, crashing the lockscreen until the next reset

Sounds like CVE-2015-3860 [0].

Nope, it's literally "twice colon" where colon is specifically the punctuation mark. פעמים נקודותיים

Ahh dreams dashed.

Dashed? Em-dashed? Hyphenated? Or just subtracted?
