This signature detects attempts to exploit a vulnerability in ht://dig, a Web content search engine for UNIX. Because ht://dig improperly validates form input, attackers can pass a maliciously crafted variable to the htsearch CGI script to read files accessible to the program user.
ht://dig is a web content search engine for Unix platforms. The software is set up to allow for file inclusion from configuration files. Any string surrounded by the opening singlw quote character ( ` ) is taken as a path to a file for inclusion, for example: some_parameter: `var/htdig/some_file` htdig will also allow included files to be specified via form input. Therefore, any file can be specified for inclusion into a variable by any web user.
