Francois Harvey has reported some vulnerabilities in Barracuda Spam Firewall, which can be exploited by malicious users to disclose and manipulate sensitive information and by malicious people to compromise a vulnerable system.
1) Input passed to the "f" parameter in "/cgi-bin/img.pl" is not properly sanitised before being used in an "open()" call. This can be exploited to disclose the content of arbitrary files via directory traversal attacks or execute arbitrary shell commands via the "|" pipe character.
2) Certain input passed to the "/cgi-bin/dig_device.cgi" and "/cgi-bin/tcpdump_device.cgi" scripts in the utility section is not properly verified before being used as arguments to the "dig" and "tcpdump" utilities. This can be exploited to disclose part of the content of files in the "cgi-bin" directory. This may also be exploited to overwrite files in the "cgi-bin" directory.
