CVE-2020-1925 : What You Need to Know

Apache Olingo versions 4.0.0 to 4.7.0 enable the potential for a Server Side Request Forgery (SSRF) attack through the AsyncRequestWrapperImpl class.

Understanding CVE-2020-1925

Apache Olingo versions 4.0.0 to 4.7.0 may allow an attacker to perform SSRF attacks by manipulating client requests.

What is CVE-2020-1925?

CVE-2020-1925 refers to a vulnerability in Apache Olingo that could be exploited for Server Side Request Forgery (SSRF) attacks, potentially leading to unauthorized access to internal resources.

The Impact of CVE-2020-1925

The vulnerability in Apache Olingo versions 4.0.0 to 4.7.0 could result in an attacker tricking a client into connecting to a malicious server, subsequently enabling the server to make the client call any URL, even those inaccessible to the attacker directly.

Technical Details of CVE-2020-1925

Apache Olingo CVE-2020-1925 exposes the following technical details:
