CVE-2024-52588

Description

In Strapi latest version, at function Settings -> Webhooks, the application allows us to input a URL in order to create a Webook connection. However, we can input into this field the local domains such as localhost, 127.0.0.1, 0.0.0.0,.... in order to make the Application fetching into the internal itself, which causes the vulnerability Server - Side Request Forgery (SSRF).

Payloads

• http://127.0.0.1:80 -> The Port is not open
• http://127.0.0.1:1337 -> The Port which Strapi is running on

Steps to Reproduce

• First of all, let's input the URL http://127.0.0.1:80 into the URL field, and click "Save".

• Next, use the "Trigger" function and use Burp Suite to capture the request / response

• The server return request to http://127.0.0.1/ failed, reason: connect ECONNREFUSED 127.0.0.1:80, BECAUSE the Port 80 is not open, since we are running Strapi on Port 1337, let's change the URL we input above into http://127.0.0.1:1337

• Continue to click the "Trigger" function, use Burp to capture the request / response

• The server returns Method Not Allowed, which means that there actually is a Port 1337 running the machine.

• If there is a real server running Strapi with many ports open, by using this SSRF vulnerability, the attacker can brute-force through all 65535 ports to know what ports are open.

Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside. Typical impact: access to internal metadata services, internal APIs, or cloud credentials.

CVE-2024-52588 has a CVSS score of 4.9 (Medium). The vector is network-reachable, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (4.25.2); upgrading removes the vulnerable code path.

Kodem intelligence

1. What is CVE-2024-52588? CVE-2024-52588 is a medium-severity server-side request forgery (SSRF) vulnerability in @strapi/admin (npm), affecting versions < 4.25.2. It is fixed in 4.25.2. Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside.
2. How severe is CVE-2024-52588? CVE-2024-52588 has a CVSS score of 4.9 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of @strapi/admin are affected by CVE-2024-52588? @strapi/admin (npm) versions < 4.25.2 is affected.
4. Is there a fix for CVE-2024-52588? Yes. CVE-2024-52588 is fixed in 4.25.2. Upgrade to this version or later.
5. Is CVE-2024-52588 exploitable, and should I be worried? Whether CVE-2024-52588 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-52588 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-52588? Upgrade @strapi/admin to 4.25.2 or later.
