When identified, common developer errors that lead to XSS vulnerabilities are mitigated by building safer defaults. For developers, Drupal has at least eight API functions for filtering output to prevent XSS attacks. Untrusted user’s content is filtered to remove dangerous elements by default. 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.ĭrupal: Drupal has a strong system for filtering user-generated content on display. XSS flaws occur whenever an application takes untrusted data and sends it to a web browser without proper validation or escaping. User passwords are salted and hashed using an algorithm based on the Portable PHP Password Hashing Framework and existing sessions are destroyed upon login and logout. Authentication cookies and a user’s name, ID, and password are managed on the server to prevent a user from easily escalating authorization. 2. Broken Authentication and Session ManagementĪpplication 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.ĭrupal: User accounts and authentication are managed by Drupal core. Drupal’s file system interaction layer limits where files can be written and alters dangerous file extensions that the server could potentially execute. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization.ĭrupal: Drupal contains a robust object-oriented database API that makes it difficult for developers to unknowingly create injection holes by automatically sanitizing query parameters and enforcing an interface. 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. We will discuss briefly the OWASP top 10 and how Drupal deals with them. Release announcements will appear at the standard You to reserve time for module updates at that time becauseĮxploits are expected to be developed within hours/days. Highly critical remote code execution vulnerabilities On Wednesday July 13th 2016 16:00 UTC that will fix There will be multiple releases of Drupal contributed modules fixes problems and publishes advisories that explain vulnerabilities and how to fix them. coordinates with core and contributed module maintainers to prepare and release fixes.validate and respond to security issues.Many security problems are prevented entirely by Drupal’s strong coding standards and rigorous community code review process.” “A dedicated security team, along with a large professional service provider ecosystem, and one of the largest developer communities in the world ensure rapid response to issues. It is important then that internet websites and applications maintain a strong security protocol that includes updating core and contributed modules.ĭrupal is a proven, secure CMP (content management platform) and application development framework that stands up to the most critical internet vulnerabilities. Even without changing a single line of application’s code, you may become vulnerable as new flaws are discovered and attack methods are refined. OWASP raises security aspects by identifying some of the most critical risks facing organizations. The list represents the most common and important vulnerabilities. OWASP monitors security concerns and publishes a top 10 list. The OWASP mission is to make software security visible, so that individuals and organizations are able to make informed decisions. The Open Web Application Security Project ( OWASP) is a 501(c)(3) worldwide not-for-profit charitable organization focused on improving the security of software. Internet security is an ever moving target. It is a reality that new flaws are being discovered and attack methods are constantly being refined.
