CVE-2001-0074

Vulnerability

A directory traversal vulnerability exists in the print.cgi script within Technote's Multicommunication Package. The script uses the board parameter directly as a filename in the open() function without sanitizing ../ character sequences, allowing remote attackers to specify arbitrary files for disclosure [1]. This affects Technote versions that include this script.

Exploitation

An unauthenticated remote attacker can exploit this vulnerability by sending a crafted request to the print.cgi script. The attacker needs to provide a path traversal sequence (e.g., ../../..) followed by the desired file's path in the board parameter. For example, a request like http://target/technote/technote/print.cgi?board=../../../../../../../../etc/passwd%00 could be used to attempt to read sensitive files [1].

Impact

Successful exploitation allows an attacker to read arbitrary files on the server that are accessible by the web-server process. This could lead to the disclosure of sensitive information, potentially aiding in further attacks against the victim system [1].

Mitigation

No specific patched version or release date is mentioned in the available references. It is recommended to disable or restrict access to the print.cgi script if possible. Users should consult Technote's official advisories for any updates or patches. The current status regarding a fix or workaround is not yet disclosed in the available references [1].
