Rule: -- Sid: 2214 -- Summary: This event is generated when an attempt is made to access mailview.cgi on an internal web server. This may indicate an attempt to exploit a directory traversal vulnerability in MailStudio 2000 2.0 and earlier. -- Impact: Information disclosure. -- Detailed Information: MailStudio 2000 is mail server software for Solaris or Linux operating systems. It contains a vulnerability where data sent to mailview.cgi is not properly parsed. This can allow an attacker to use directory traversal techniques (/../) within the "html" parameter to view arbitrary files on the system, including other users' email, configuration files, and password files. -- Affected Systems: Systems running MailStudio 2000 2.0 and earlier. -- Attack Scenarios: An attacker sends a specially crafted HTTP request to a vulnerable web server with another user's email file as the html argument. The attacker will then be able to view the file. -- Ease of Attack: Simple. Exploits exist. -- False Positives: If a legitimate remote user accesses mailview.cgi, this rule may generate an event. -- False Negatives: None known. -- Corrective Action: It is not known if this vulnerability has been fixed.
