Denial of Service Vulnerability in Apache Olingo by Malicious Retry-After Header

CVE-2019-17555

What is CVE-2019-17555?

A vulnerability exists in the AsyncResponseWrapperImpl class of Apache Olingo versions 4.0.0 to 4.6.0, where the application processes the Retry-After header improperly. If a malicious server sends a substantially large value in this header, it can result in the Thread.sleep() method being invoked with an excessively long duration, potentially leading to a Denial of Service condition. This vulnerability underscores the importance of validating header values to prevent misuse and maintain system availability.
