Lessons learned: How a severe vulnerability in the OWASP ModSecurity Core Rule Set sparked much-needed change The Daily Swig

SSRF flaws occur when a web app fetches a remote resource without validating the user-supplied URL. Attackers can coerce the app to send a request to an unexpected destination—even if it’s secured by a firewall, VPN, or other network access control list (ACL). In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page. Students will have an opportunity to validate their knowledge gained throughout each of the courses with practice and graded assessments at the end of each module and for each course. Practice and graded assessments are used to validate and demonstrate learning outcomes.

Reviews from learners

Once developers know how to build a secure thing, they need to understand how to do so in concert with others. The broader picture of this is the maturity level of the team performing all the security aspects of the greater SSDLC – and when we say SSDLC at OWASP, we mean OWASP SAMM. However, to help reduce the likelihood of another high-impact bug slipping through the net, the CRS maintainers have implemented new practices, guidelines, and a bug bounty program to further secure the technology. Injection is a broad class of attack vectors where untrusted input alters app program execution. This can lead to data theft, loss of data integrity, denial of service, and full system compromise. He highlights themes like risk re-orientation around symptoms and root causes, new risk categories, and modern application architectures.

Learn what to do and avoid—as modern app development, software re-use, and architectural sprawl across clouds increases this risk. Failures can result in unauthorized disclosure, modification or destruction of data, and privilege escalation—and lead to account takeover (ATO), data breach, fines, and brand damage. In late February 2024, after receiving a few support requests, the OWASP Foundation became aware of a misconfiguration of OWASP’s old Wiki web server, leading to a data breach involving decade+-old member resumes.

About OWASP

The OWASP Top 10 is a broad consensus about the most critical security risks to web applications. Our platform includes everything needed to deploy and manage an application securityeducation program. We promote security awareness organization-wide with learning that isengaging, motivating, and fun. We emphasize real-world application through code-basedexperiments and activity-based achievements.

“What we did not realize was that an attacker could meet these conditions by abusing the PATH_INFO part of the request URI,” he continued. Folini said that the CRS team has been slowly expanding its DevOps practices “for several years” since they OWASP Lessons took over in 2016. In this post I’ll focus on the Cross-Site Scripting (XSS) lessons, which I was recently able to solve. As software becomes more configurable, there is more that needs to be done to ensure it is configured properly and securely.

Train with OWASP Training.

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. If you only want to read and view the course content, you can audit the course for free. We help IT and security professionals advance their careers with skills development and certifications while empowering all employees with security awareness and privacy training to stay cyber-safe at work and home. Security Journey to respond to the rapidly growing demand from clients of all sizes forapplication security education. Folini also said that by introducing a formal checklist and a bug bounty program, code can be extensively reviewed, both internally and externally.

• “Even an inactive rule exclusion package could cripple the entire rule set,” he said.
• The OWASP Foundation has been operational for nearly two decades, driven by a community ofcorporations, foundations, developers, and volunteers passionate about web applicationsecurity.
• The longer an attacker goes undetected, the more likely the system will be compromised.
• Injection is a broad class of attack vectors where untrusted input alters app program execution.
• Do you want live training with an AWS expert where you’ll get the chance to ask questions and receive real-time feedback?

Even though the app does explain the basic concepts, the explanations are nowhere good enough to solve the exercises provided. Open Source software exploits are behind many of the biggest security incidents. The recent Log4j2 vulnerability is perhaps the most serious risk in this category to date.

It is designed to serve as a secure coding kick-start tool and easyreference, to help development teams quickly understand secure codingpractices. The OWASP Foundation has been operational for nearly two decades, driven by a community ofcorporations, foundations, developers, and volunteers passionate about web applicationsecurity. As a non-profit, OWASP releases all its’ content for free use to anyone interested inbettering application security. All of our projects ,tools, documents, forums, and chapters are free and open to anyone interested in improving application security.

• We’ll use demos, graphics and real-life examples to help you understand the details of each of these risks.
• Open Source software exploits are behind many of the biggest security incidents.
• You’ll be guided through a recommended curriculum built by AWS experts that you can take at your own pace.
• Attackers can coerce the app to send a request to an unexpected destination—even if it’s secured by a firewall, VPN, or other network access control list (ACL).
