Estive analisando o Release Candidate do Top 10 2007 do OWASP (Open Web Application Security Project) e pude perceber que o projeto está sempre pesquisando e atendendo as tendências no desenvolvimento seguro de aplicações web.
A1 – Cross Site Scripting (XSS)XSS flaws occur whenever an application takes user supplied data and sends it to a web browser without first validating or encoding that content. XSS allows attackers to execute script in the victim’s browser which can hijack user sessions, deface web sites, etc.
A2 – Injection FlawsInjection flaws, particularly SQL injection, are common in web applications. Injection occurs when user-supplied data is sent to an interpreter as part of a command or query. The attacker’s hostile data tricks the interpreter into executing unintended commands or changing data.
A3 – Insecure Remote File IncludeCode vulnerable to remote file inclusion allows attackers to include hostile code and data, resulting in devastating attacks, such as total server compromise.
A4 – Insecure Direct Object ReferenceA direct object reference occurs when a developer exposes a reference to an internal implementation object, such as a file, directory, database record, or key, as a URL or form parameter. Attackers can manipulate those references to access other objects without authorization.
A5 – Cross Site Request Forgery (CSRF)A CSRF attack forces a logged-on victim’s browser to send a pre-authenticated request to a vulnerable web application, which then forces the victim’s browser to perform a hostile action to the benefit of the attacker.
A6 – Information Leakage and Improper Error HandlingApplications can unintentionally leak information about their configuration, internal workings, or violate privacy through a variety of application problems. Attackers use this weakness to violate privacy, or conduct further attacks.
A7 – Broken Authentication and Session ManagementAccount credentials and session tokens are often not properly protected. Attackers compromise passwords, keys, or authentication tokens to assume other users dentities.
A8 – Insecure Cryptographic StorageWeb applications rarely use cryptographic functions properly to protect data and credentials. Attackers use weakly protected data to conduct identity theft and other crimes, such as credit card fraud.
A9 – Insecure CommunicationsApplications frequently fail to encrypt network traffic when it is necessary to protect sensitive communications.
A10 – Failure to Restrict URL AccessFrequently, the only protection for sensitive areas of an application is links or URLs are not presented to unauthorized users. Attackers can use this weakness to access and perform unauthorized operations.
A principal novidade é a inclusão do Cross Site Request Forgery uma variação do Cross Site Scripting que está entre as principais ameaças da Web 2.0.
Atendendo a demanda dos profissionais que desenvolvem em php que, segundo o NIST é a linguagem com mais aplicações web vulneráveis, o OWASP hoje possui não só o Stinger, um sanitizador, filter de inputs para aplicações desenvolvida em java, mas, um projeto semelhante para PHP.
