Server-Side Request Forgery (SSRF) is a significant vulnerability that enables attackers to manipulate a server into making unauthorized requests. This can compromise sensitive data, gain access to internal systems, or allow remote code execution. The utilization of SSRF can lead to the leakage of IAM credentials and internal service access. Affected: web applications, cloud services, internal systems.
Keypoints :
- SSRF allows attackers to send unintended requests through a compromised server.
- It can lead to the exposure of sensitive data and remote code execution.
- Internal services should not be accessible to the public but can be targeted through SSRF.
- Manipulating URLs helps in discovering internal services or sensitive data.
- AWS SSRF can leak IAM role credentials, thus compromising cloud resources.
- Symlink can be used to read arbitrary files on the server.
- Download scripts that allow external URLs can be exploited to exfiltrate source code or credentials.
- Exploiting SSRF can result in accessing sensitive information such as MySQL credentials.
