VAR-200001-0040

Vulnerability from variot - Updated: 2025-04-03 22:19

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

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
