nodejs: Response splitting vulnerability using Unicode characters
Published Apr 7, 2016
7.5
HIGHCVSS 3.0
EPSS 7.01%
Description
The HTTP header parsing code in Node.js 0.10.x before 0.10.42, 0.11.6 through 0.11.16, 0.12.x before 0.12.10, 4.x before 4.3.0, and 5.x before 5.6.0 allows remote attackers to bypass an HTTP response-splitting protection mechanism via UTF-8 encoded Unicode characters in the HTTP header, as demonstrated by %c4%8d%c4%8a.
