Server-Side Request Forgery (SSRF) is a vulnerability where a web application fetches remote resources on behalf of a user, allowing attackers to trick the application into making malicious requests. This can bypass security controls and expose sensitive internal resources. Learn more from OWASP.
SSRF vulnerabilities are dangerous because they allow attackers to bypass firewalls and access control lists (ACLs), potentially accessing sensitive data or performing unauthorized actions within an organization's network.
Common SSRF attack scenarios include ACL bypass, where attackers access internal resources by exploiting trusted application IPs, and port scanning, where attackers use the vulnerable application to scan internal network ports for exploitable services.
In 2019, Capital One suffered a breach due to an SSRF vulnerability in its web application firewall (WAF), which allowed an attacker to access AWS metadata and sensitive customer data. The incident affected approximately 100 million Americans and 6 million Canadians. Read the case study.
Best practices include enforcing least privilege access, network segmentation, using allowlists for URLs, sanitizing user input, parsing responses to avoid leaking sensitive data, and disabling redirects to prevent bypasses.
Ionix proactively manages SSRF and other OWASP vulnerabilities by simulating exploitation during risk assessments, highlighting attack vectors and security gaps, and offering improved control of the digital attack surface. Learn more about Ionix's threat exposure management.

Network segmentation isolates public-facing applications from the rest of the network, minimizing the impact of SSRF vulnerabilities and reducing the risk of lateral movement by attackers.
Sanitizing user input prevents attackers from using obfuscated or malformed URLs to evade allowlists and trick applications into fetching unauthorized resources, reducing the risk of SSRF exploitation.
Disabling redirects ensures that attackers cannot use redirection techniques to bypass allowlists and access unapproved resources, strengthening SSRF defenses.
Excessive permissions assigned to applications can be abused by attackers exploiting SSRF vulnerabilities, allowing unauthorized access to sensitive resources. Enforcing least privilege reduces this risk.
Ionix's risk assessment process involves simulating exploitation of vulnerabilities, evaluating attack vectors, and identifying security gaps to help organizations proactively manage risks like SSRF.
Allowlists restrict user requests to approved resources, specifying schema, port, and destination, which limits the potential for SSRF exploitation by attackers.
Parsing and sanitizing responses from remote resources prevents sensitive information, such as internal IP addresses or error logs, from being exposed to users through SSRF exploitation.
Ionix improves application security posture by proactively identifying, simulating, and remediating vulnerabilities like SSRF, ensuring organizations have better control over their digital attack surface.

Some web applications fetch remote resources on behalf of the user. For example, a website designed to process user-provided images may allow them to provide a URL from which the application would fetch the image.
In this article
When accepting a URL from a user to make a remote request, it’s vital to validate that this URL meets expectations. Otherwise, this introduces server-side request forgery vulnerabilities (SSRF), which allow a malicious user to make malicious requests to bypass security controls.
A web application deployed within an organization’s environment may have different levels of access than an external attacker. For example, firewalls may allow requests from the web app to various internal services so that the tool can fetch data from a database or take similar actions.
SSRF vulnerabilities are dangerous because they allow an attacker to trick an application into performing requests on the attacker’s behalf. This may allow an attacker to bypass firewalls or other security controls to access sensitive data or take other actions against the business.
SSRF vulnerabilities primarily allow an attacker to bypass access controls designed to ensure that only internal or approved devices are allowed to access a particular resource. Some ways that an attacker could abuse this type of vulnerability include the following:
An organization may have access control lists (ACLs) in place to restrict access to internal resources. For example, certain systems or applications may only be accessible from known IP addresses.
An SSRF vulnerability may allow an attacker to bypass these restrictions by having the vulnerable web application make requests on its behalf. Since these requests would originate from a company-owned IP address — the IP address of the web server hosting the vulnerable application — they would be approved, while ones originating directly from the attacker would not. This could allow the attacker to access sensitive information from within the organization’s network.
Port scanning can provide useful information about an organization’s network and the various applications active on it. With enough information about running applications, an attacker may be able to identify and exploit unpatched vulnerabilities in the code.
Often, companies block port scanning at the network boundary to prevent this type of reconnaissance. However, SSRF vulnerabilities may enable an attacker to trick the vulnerable application, which is inside the protected boundary, into performing the port scan on its behalf.
In 2019, Capital One suffered a breach related to an SSRF vulnerability in the financial institution’s web application firewall (WAF). The WAF was assigned excessive permissions within the organization’s AWS environment and was tricked into performing requests on the attacker’s behalf to the AWS metadata service. By doing so, it generated temporary credentials that the attacker could use to access sensitive information within the AWS environment.
The attacker was a former AWS employee who accessed the data of approximately 100 million American customers and 6 million Canadians. This included highly sensitive personal information, such as Social Security Numbers (SSN), bank account numbers, credit scores, and more.
SSRF vulnerabilities have the potential to undermine an organization’s application and data security policies. Some best practices to manage these risks include:
SSRF vulnerabilities can be dangerous because they undermine security controls implemented outside of the application. If the application is trusted by firewalls and ACLs, then the attacker can use it to make the requests that they can’t make directly.
The IONIX platform helps organizations to proactively manage the security risks of SSRF and other OWASP vulnerabilities. When performing a risk assessment, it simulates the exploitation of these vulnerabilities, highlighting potential attack vectors and security gaps.
