Unspecified vulnerability in CGI.pm 3.50 and earlier allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unknown vectors. NOTE: this issue exists because of an incomplete fix for CVE-2010-2761.

CRLF injection vulnerability in the header function in (1) CGI.pm before 3.50 and (2) Simple.pm in CGI::Simple 1.112 and earlier allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via vectors related to non-whitespace characters preceded by newline characters, a different vulnerability than CVE-2010-2761 and CVE-2010-3172.

The multipart_init function in (1) CGI.pm before 3.50 and (2) Simple.pm in CGI::Simple 1.112 and earlier uses a hardcoded value of the MIME boundary string in multipart/x-mixed-replace content, which allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via crafted input that contains this value, a different vulnerability than CVE-2010-3172.

Cross-site scripting (XSS) vulnerability in start_form() of CGI.pm allows remote attackers to insert web script via a URL that is fed into the form's action parameter.
