DB error not handled by the web application

By
Incercam astazi sa caut care este cea mai buna ruta pentru a merge din Cluj-Napoca in Arad, iar domnul Google m-a dus la urmatoarea adresa url:
http://mersul-trenurilor.infoturism.ro/mersul_trenurilor_arad_cluj-napoca.php
Pagina returnata avea urmatorul continut:
SELECT DISTINCT traseu.id, traseu.ora, traseu.id_tren,
traseu.id_statie, gari.nume FROM traseu, gari
WHERE traseu.id_statie = gari.id
AND id_tren
IN (536,534,1834,1843,1766)
ORDER BY traseu.ordine, traseu.id1054
- Unknown column 'traseu.ora' in 'field list'
Rezultatul returnat mi s-a parut destul de dragut, mai ales ultima parte a sa. In mod normal ar fi trebuit sa vedem o pagina de eroare frumoasa, dar in schimb apare un SELECT, care ne expune o mica parte din baza de date.
O persoana cu putina imaginatie poate ar putea sa execute o comanda SQL precum un DELETE.
In cazul in care lucrati la o aplicatie de orice fel (in special web) nu uitati sa tratiti mesajele de eroare intr-un mod corespunzator, iar la un end-user sa nu afisati niciodate query din baza de date.
Un mesaj generic este mai mult decat suficient pentru un muritor.

    Vreun programator PHP care nu o auzit de set_error_handler.. - macar in ASP.NET avem customErrors care are valoarea implicita remoteOnly, deci si daca programtrul uita, e cat de cat safe by default daca nu s-a jucat la customErrors.

How to audit an Azure Cosmos DB

By
In this post, we will talk about how we can audit an Azure Cosmos DB database. Before jumping into the problem let us define the business requirement: As an Administrator I want to be able to audit all changes that were done to specific collection inside my Azure Cosmos DB. The requirement is simple, but can be a little tricky to implement fully. First of all when you are using Azure Cosmos DB or any other storage solution there are 99% odds that you’ll have more than one system that writes data to it. This means that you have or not have control on the systems that are doing any create/update/delete operations. Solution 1: Diagnostic Logs Cosmos DB allows us activate diagnostics logs and stream the output a storage account for achieving to other systems like Event Hub or Log Analytics. This would allow us to have information related to who, when, what, response code and how the access operation to our Cosmos DB was done. Beside this there is a field that specifies what was th...

Why Database Modernization Matters for AI

By
  When companies transition to the cloud, they typically begin with applications and virtual machines, which is often the easier part of the process. The actual complexity arises later when databases are moved. To save time and effort, cloud adoption is more of a cloud migration in an IaaS manner, fulfilling current, but not future needs. Even organisations that are already in the cloud find that their databases, although “migrated,” are not genuinely modernised. This disparity becomes particularly evident when they begin to explore AI technologies. Understanding Modernisation Beyond Migration Database modernisation is distinct from merely relocating an outdated database to Azure. It's about making your data layer ready for future needs, like automation, real-time analytics, and AI capabilities. AI needs high throughput, which can be achieved using native DB cloud capabilities. When your database runs in a traditional setup (even hosted in the cloud), in that case, you will enc...

Azure Service Bus - How to extend the lock of a message | RenewLock

By
In this post we will discuss about Azure Service Bus Topics and Queues, with a special focus on Peek and Lock feature. Introduction Azure Service Bus is a messaging system that allows us to send messages between different systems in a reliable and easy way. A lot of concepts from ESB are implemented by Service Bus, allowing us to do do magic stuff with messages. There are two ways to consume messages from Service Bus Peek and Lock - locks a message for a specific time internal and notify Service Bus when we want to mark the message as processed (removed from Service Bus) Receive and Delete  - once a message is received from Service Bus, it is also deleted automatically from the messaging system Peek and Lock When using Peek and Lock, by default we lock the message for 60 seconds. This means that in this time interval the message is not available/visible for other consumers. Once we process the message we can mark it as processed. If we don't mark the message as processe...
