Web Application Pentest

The web is the business platform of the first part of 21st. Companies do pretty much everything online and they either have a web portal displaying information or they bring highly sophisticated services to their customers ranging from social networks to personal medical records or sensitive data. In any case, it is important to keep these applications secure and test them against the latest security vulnerabilities.


As with Network Penetration tests, our vision of WebApp penetration testing methodology is to merge the classic phases of the assessment with latests threads and attacks from the real world. We do this in order bring not only the information security requires procedures and tests, but to also give the client the best possible actual security posture for his environment. Most companies concentrate in reporting lots of meaningless vulnerabilities any automated scanner can provide without given any insight into how they could be used, wether attackers even exploit these issues nowadays or if the issues could actually damage the organization in question. By mixing the classic methodology and introducing a refreshed view at security concentrating in mimicking real criminals intent we aim to bring more and better value into each reported vulnerability for each step of the assessment.

OWASP Top 10

Having said this, we make sure our tests satisfy all compliance requirements and we cover OWASP Top 10 list of vulnerabilities to ensure that we are always looking for what the security industry dictaminates as the most important and relavant issues today.


Injection flaws, such as SQL, OS, and LDAP injection occur when untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization.

Broken Auth &
Session Mgmnt.

Application functions related to authentication and session management are often not implemented correctly, allowing attackers to compromise passwords, keys, or session tokens, or to exploit other implementation flaws to assume other users’ identities.


XSS flaws occur whenever an application takes untrusted data and sends it to a web browser without proper validation or escaping. XSS allows attackers to execute scripts in the victim’s browser which can hijack user sessions, deface web sites, or redirect the user to malicious sites.

Insecure Direct
Object Ref.

A direct object reference occurs when a developer exposes a reference to an internal implementation object, such as a file, directory, or database key. Without an access control check or other protection, attackers can manipulate these references to access unauthorized data.

Security Misconfig.

Good security requires having a secure configuration defined and deployed for the application, frameworks, application server, web server, database server, and platform. Secure settings should be defined, implemented, and maintained, as defaults are often insecure. Additionally, software should be kept up to date.

Sensitive Data

Many web applications do not properly protect sensitive data, such as credit cards, tax IDs, and authentication credentials. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Sensitive data deserves extra protection such as encryption at rest or in transit, as well as special precautions when exchanged with the browser.

Missing Level
Access Control

Most web applications verify function level access rights before making that functionality visible in the UI. However, applications need to perform the same access control checks on the server when each function is accessed. If requests are not verified, attackers will be able to forge requests in order to access functionality without proper authorization.

Request Forgery

A CSRF attack forces a logged-on victim’s browser to send a forged HTTP request, including the victim’s session cookie and any other automatically included authentication information, to a vulnerable web application. This allows the attacker to force the victim’s browser to generate requests the vulnerable application thinks are legitimate requests from the victim.


Components, such as libraries, frameworks, and other software modules, almost always run with full privileges. If a vulnerable component is exploited, such an attack can facilitate serious data loss or server takeover. Applications using components with known vulnerabilities may undermine application defenses and enable a range of possible attacks and impacts.

Redirects &

Web applications frequently redirect and forward users to other pages and websites, and use untrusted data to determine the destination pages. Without proper validation, attackers can redirect victims to phishing or malware sites, or use forwards to access unauthorized pages.
