Dr_insane has discovered three vulnerabilities in ArGoSoft Mail Server, which can be exploited by malicious people to cause a DoS (Denial of Service), disclose sensitive information, and create arbitrary directories on a vulnerable system.

1) Input passed to the username in "addnewuser" isn't properly sanitised before being used to create directories. This can be exploited to create a directory in an arbitrary location via directory traversal attacks.

2) An error in the handling of long passwords (about 800 bytes) in "addnewuser" can be exploited to cause a vulnerable service to consume a large amount of CPU resources.

3) The problem is that the script "viewlogs.pl" can be accessed without any authentication. This can be exploited to disclose some potentially sensitive logging information.

The vulnerabilities have been confirmed in version 1.8.7.4. Other versions may also be affected.

Solution
Update to version 1.8.7.8.
