(Mandrake Issues Fix) CVS 'History' Command Discloses to Remote Authenticated Users Whether Files Exist or Not
SecurityTracker Alert ID:  1011795
SecurityTracker URL:  http://securitytracker.com/id/1011795
CVE Reference:   CVE-2004-0778   (Links to External Site)
Date:  Oct 20 2004
Impact:   Disclosure of system information, Disclosure of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 1.11.17 and 1.12.9
Description:   iDEFENSE reported an information disclosure vulnerability in CVS. A remote authenticated user can determine if certain specified files and directories exist.

It is reported that there is an undocumented switch in the 'history' command in 'src/history.c'. A remote authenticated user can supply an arbitrary filename to the '-X' command switch (used to specify the history file) and then analyze the resulting error messages to determine if the named file exists on the target system and if the CVS process has access to the file.

The vendor was reportedly notified on July 22, 2004. [Editor's note: This notification date is after the date of the vendor fix (June 9, 2004).

The original advisory is available at:

http://www.idefense.com/application/poi/display?id=130&type=vulnerabilities

Impact:   A remote authenticated user can determine if files or directories exist on the target system. The user can also determine if the CVS daemon has access to the files or directories.
Solution:   Mandrake has issued a fix.

 Package name:           cvs
 Advisory ID:            MDKSA-2004:108
 Date:                   October 19th, 2004

 Affected versions:	 10.0, 9.2, Corporate Server 2.1
 ______________________________________________________________________

 Problem Description:

 iDEFENSE discovered a flaw in CVS versions prior to 1.1.17 in an
 undocumented switch implemented in CVS' history command.  The -X
 switch specifies the name of the history file which allows an attacker
 to determine whether arbitrary system files and directories exist and
 whether or not the CVS process has access to them.
 
 This flaw has been fixed in CVS version 1.1.17.
