In Big4 it is an "us & them" culture between back office services and advisory teams. Rarely will the two ever meet and when they do there will be great resistance from the back office teams. This is the sort of shit storm that results.

I'm pretty certain that use of AWS doesn't preclude comparable secure, performant, reliable services being provided for SAP.
ESNC & PwC aren't in competition. PwC's ACE is an audit support tool. It extracts the information used to audit SAP systems, generally for the purposes of supporting statutory audit. Primarily ACE performs Segregation of Duties reviews. The ESNC products are more focused towards technical security - VAs etc.
Re: "manipulate accounting documents and financial results,"
In the U.K. Deloitte hoovered up the AA audit teams but it varied for other countries.
Putting this into context, this is crappy coding but not uncommon among vendor or SAP code. I would also be surprised if this was remotely executable for any organisations following the standard security guidance provided by SAP.
I'm not that surprised that something like this has been picked up, there are lots of vendor tools using exactly the same lazy techniques to auto generate code. PwC are unlucky as they are an easy target & their response was pretty crappy. They really should have been whiter than white. There will be plenty of vendors scrambling to check their code now. I would have imagined a fair few of them would have been scanned by VirtualForge who pretty much own the SAP code scanning space. They don't really need to publicise though. You have to also question SAP for remaining to make those techniques available, doing that would likely require a lot of refactoring (and vendors are "encouraged" to not scan SAP code outside of direct collaboration with them)
For those commenting on the tool, ACE is the name of many junior SAP auditors lives. It uses client side ABAP programs to generate extract files which are taken processed separately to identify stuff like segregation of duties conflicts, change control settings, configurable control settings etc. From what I remember it can't be used to make updates though it sounds like the programs could be subverted.
I'm not disputing that there are 256-odd systems discoverable with that service.
It has been a slow news month for SAP with regard to reporting security bugs and for the article (not the vendor) to say it is critical is simply not the case. It relates to information disclosure which at worst, could be used to support an attack to be crafted.
A fair bit of hyperbole here. The authentication bug was for an information service & the info that can be gained isn't particularly useful, certainly not a critical prior and not classified by SAP as such.
With regard to giving code to customers - in general it is (with a few exceptions). While it's not open source, it is available to anyone with an SAP system - a lot of customers & partners.
Re: Can understand SAP having issues
Historically I don't think SAP would have been too bothered, after all where their customers data is is not their problem.
Now SAP are going all out on a cloud strategy where SAP hosts, all of a sudden it can bite them on the bum rather than just their customers.
Yes, this has been documented in SAP help & SAP recommends to change the default shipped key. I don't consider this particularly newsworthy but then again I am not trying to flog a product!
Re: Why "Crypto"?
There is a common misconception with the SAP industrye that traffic is encrypted rather than compressed & obfuscated. SAP recommend that encryption is enabled but <10% of customers actually do it (either using SAP tech or other solutions). It seems that the term has been used to drum up a bit more excitement.
Re: Nice picture ....
It's Crawley. The kit was probably nicked in the time it took the 'tog to press the shutter release and the shutter errrr releasing.
They would have had a good idea that that the patch wouldn't land before the session, pulling out at last minute sounds to me like a publicity stunt.
The ERPScan team do a good job, no need for marketing stunts.
Putting it into perspective it's not like the competition are any better when comparing like-for-like.
Re: Is it just me
When it works it's not unproductive but the rest still apply.

Re: Slow And Painful
SAP have really upped their game in the security area over the last 5 years. While many, many customers subscribe to security by obscurity, the same doesn't apply to SAP.
The problem is that many customers will not invest in securing their assets using standard mechanisms that SAP have provided for years, party because it is, just like you say, an utter faff to patch around release cycles.
Yet another exploit facilitated through too much RFC access. Who woulda thunk it.
Plenty are at it
I've got plenty of clients who have done the same. Set up an entity in a low(sh)-tax location e.g. Switzerland.
Step 1. Transport some staff to Head Office & claim that's where decisions are made, sales happen & risk is taken (therefore where tax should be paid)
Step 2. Set up new companies overseas & transfer manufacturing, service, distribution and local procurement into those companies.
Step 3. Operate tolling system where H/O owns stock & pays local manufacturers to covert raw materials into product & ship on behalf of Head Office.
A few honchos move, lots of people get new contracts in the new companies.
Nothing new here
We've been able to find SAP systems through internet searches since the days of ITS and early SAP Portal. It would have been a trivial matter to try some default user accounts.
Other posters have commented on the reality of the tests & possible scaremongering tactics. For all their sins SAP does generally produce reasonably secure software. The problem is that most of those paid to secure it do not understand how to secure the assets using standard delivered SAP functionality and standard security techniques.
Unfortunately this is no surprise to many of us working in the SAP security field. SAP are working very hard to improve, unfortunately clients are struggling to care.
Some key themes:
1. Security admins main knowledge is around building roles/permission structures and user admin. The technical side is neglected (despite being covered quite well in certification) and there is a big gap.
2. Patching is time consuming and many organisations require full regression testing for each set of patches. Across 20 productive systems (each with a supporting application stack of 2-5 systems) covering a full scope of business processes that comes at quite a cost (though not as much as a breach of course).
3. IS teams rarely talk to SAP teams. SAP has been treated as a silo & there is a disconnect between IS and their SAP counterparts. Many SAP admins do not understand the impact of vulnerabilities, the IS teams struggle to use terms that the SAP guys understand.
Fortunately some people do "get it" and plenty of orgs are doing good stuff & SAP is committed to make it easy for people to do the right thing.
