gsd-2015-7519
Vulnerability from gsd
Modified
2015-11-23 00:00
Details
It is possible in some cases, for clients to overwrite headers set by the server, resulting in a medium level security issue. Passenger 5 uses an SCGI-inspired format to pass headers to Ruby/Python applications, while Passenger 4 uses an SCGI-inspired format to pass headers to all applications. This implies a conversion to UPPER_CASE_WITH_UNDERSCORES whereby the difference between characters like '-' and '_' is lost.
