This tool was built to test (XSS|SSRF|CORS|SSTI|IDOR|RCE|LFI|SQLI) vulnerabilities - pikpikcu/XRCross Simply This bug allowed me to achieve RCE using a SSRF Vulnerability . An SSRF attack involves tricking a server into accessing a resource it shouldn't be touching on behalf of the attacker. Header Injection and Limited SSRF (CVE-2019-2438) When we started this research, the main vulnerability class targeted was Server Side Request Forgery (SSRF), in short, the capability to request web pages from another domain or IP. Peter Adkins on 29 May 2017. read This post details an example of chaining three relatively trivial vulnerabilities to achieve remote code execution on a Bug Bounty target. Server Side Request Forgery on the main website for The OWASP Foundation. ; iam_privesc_by_rollback – Enumerate IAM policy versions and roll back to a previous version with higher privileges.

The attacker gained access to a set of AWS access keys by accessing the AWS EC2 metadata service via a SSRF vulnerability. Blog Logo. We will be using a real-world example, exploiting a vulnerability we discovered in a commercial Business Intelligence product called Dundas BI. In this post, we’ll discuss how to prevent or mitigate compromise of credentials due to certain classes of vulnerabilities such as Server Side Request Forgery (SSRF) and XML External Entity (XXE) injection. Mar 12, ... What’s AWS Elastic Beanstalk? SSRF’s up! Attackers can also use SSRF to make requests to other internal resources that the web server has access to, which are not publicly available. Escalating SSRF to RCE. We focus on the URL parameter from the esi:include tag. If an attacker has remote code execution (RCE) or local presence on the AWS server, these methods discussed will not prevent compromise. AWS Elastic Beanstalk, is a Platform as a Service (PaaS) offering from AWS for … An attacker can even get creative with SSRF and run port scans on internal IPs. In some situations, the SSRF vulnerability might allow an attacker to perform arbitrary command execution. A successful SSRF attack can often result in unauthorized actions or access to data within the organization, either in the vulnerable application itself or on other back-end systems that the application can communicate with. In this section, we'll explain what server-side request forgery is, describe some common examples, and explain how to find and exploit various kinds of SSRF vulnerabilities. The scenarios included at the launch are: rce_web_app – Find the secret endpoint and exploit a web app remote code execution vulnerability to gain root EC2 access inside a VPC.

Escalating SSRF to RCE: I went to try some potential exploitation scenarios. Pivoting from blind SSRF to RCE with HashiCorp Consul.
