CVE-2020-17527: Tomcat: hassas bilgi ifşası

Yayın: 3 Aralık 2020 22:15 · Güncelleme: 6 Kasım 2026 09:48

Açıklama (NVD)

While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests.
