TITLE
Nortel Contivity Switch Remote Denial of Service Attack and File Leak Vulnerability
Trust: 1.0
DESCRIPTION
cgiproc CGI script in Nortel Contivity HTTP server allows remote attackers to read arbitrary files by specifying the filename in a parameter to the script. The Contivity series is an external network switch product developed by Nortel. The newer Contivity switch includes an httpd server running on the VxWorks operating system to provide a remote Web-based management interface. A vulnerability exists in the "cgiproc" script implementation of the Web management interface of the Contivity series switches. A remote attacker could use this vulnerability to conduct a denial of service attack on the switch or view arbitrary system files. Because the user input is not sufficiently filtered, if you pass metacharacters to the cgiporc program, such as "!" Or "$", the system will crash. Another vulnerability of cgiproc is the lack of authentication when requesting a management page. This enables an attacker to view any file in the web server. A total system crash can occur as a result of exploiting a vulnerability in a cgi-bin program called "cgiproc" that is included with the webserver. If metacharacters such as "!", or "$" are passed to cgiproc, the system will crash (because the characters are not escaped). foo <foo@blacklisted.intranova.net> provided the following example: http://x.x.x.x/manage/cgi/cgiproc?$ [crash] No evidence of this problem being exploited is saved in the logs. foo <foo@blacklisted.intranova.net> also provided an example for this vulnerability: http://x.x.x.x/manage/cgi/cgiproc?Nocfile=/name/and/path/of/file. (interesting places to look: /system/filelist.dat, /system/version.dat, /system/keys, /system/core, etc.) All that is written to the logs when this is exploited is below: 09:44:23 tEvtLgMgr 0 : Security [12] Management: Request for cgiproc denied. requires login In order to perform the operations detailed in the report, the "attackers" must be internal, private side users or authenticated tunnel users and the site administrator must allow them HTTP as a management protocol
