Summary

Apache Juneau before 9.2.1 passes response header values and redirect targets to the servlet container without sanitizing them. The flaw is CWE-113, where CR/LF sequences in HTTP headers are not neutralized. A remote, unauthenticated client can inject header lines or redirect users to an arbitrary external site when an application sets a header or redirect target from request data.

Description from the CNA

Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') vulnerability in Apache Juneau. The Apache Juneau REST server passed response header values and redirect targets to the servlet container unchecked. An application that sets a response header or redirect target from request data could let a remote client inject header lines (where the servlet container does not itself reject CR/LF) or redirect users to an arbitrary external site. The framework itself does not build headers or redirects from request data; exposure depends on application code. This issue affects Apache Juneau: through 9.2.0. Users are recommended to upgrade to version 9.2.1, which fixes the issue. Header values are now sanitized by default; applications that build redirect targets from request data must also switch from sendRedirect() to the new sendSafeRedirect().
