Name of the Vulnerable Software and Affected Versions:
Undertow (affected versions not specified)
Description:
A vulnerability was found in Undertow where the
ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
