Summary

HTTP response splitting in CGI

Details

Ruby gem cgi.rb prior to versions 0.3.5, 0.2.2 and 0.1.0.2 allow HTTP header injection. If a CGI application using the CGI library inserts untrusted input into the HTTP response header, an attacker can exploit it to insert a newline character to split a header, and inject malicious content to deceive clients. This issue has been patched in versions 0.3.5, 0.2.2 and 0.1.0.2.

gsd-2021-33621

Vulnerability from gsd

Modified

2022-11-18 00:00

Details

cgi.rb in Ruby through 2.6.x, through 3.0x, and through 3.1.x allows HTTP header injection. If a CGI application using the CGI library inserts untrusted input into the HTTP response header, an attacker can exploit it to insert a newline character to split a header, and inject malicious content to deceive clients.
