nullbyte Posted May 21, 2008 Report Posted May 21, 2008 Buna, recent am luat .bat-ul acela ce scoate reclamele din Yahoo! 8. M-am uitat la cod:@ECHO OFFTITLE Remove ads from Yahoo Messenger 8> %TEMP%.\noYMads.reg ECHO REGEDIT4>>%TEMP%.\noYMads.reg ECHO.>>%TEMP%.\noYMads.reg ECHO [HKEY_CURRENT_USER\Software\Yahoo\Pager\YUrl]>>%TEMP%.\noYMads.reg ECHO "Messenger Ad"="*">>%TEMP%.\noYMads.reg ECHO "Webcam Upload Ad"="*">>%TEMP%.\noYMads.reg ECHO "Webcam Viewer Ad"="*">>%TEMP%.\noYMads.reg ECHO "Webcam Viewer Ad Big"="*">>%TEMP%.\noYMads.reg ECHO "Webcam Viewer Ad Medium"="*">>%TEMP%.\noYMads.reg ECHO "Change Room Banner"="*">>%TEMP%.\noYMads.reg ECHO "Conf Adurl"="*">>%TEMP%.\noYMads.reg ECHO "Chat Adurl"="*">>%TEMP%.\noYMads.reg ECHO "Y Content"="*"REGEDIT /S %TEMP%.\noYMads.regDEL %TEMP%.\noYMads.regATTRIB -R "%PROGRAMFILES%\Yahoo!\Messenger\Cache\urls.xml"ECHO "" >"%PROGRAMFILES%\Yahoo!\Messenger\Cache\urls.xml" ATTRIB +R "%PROGRAMFILES%\Yahoo!\Messenger\Cache\urls.xml"M-am gandit: Yahoo navigheaza folosind Iexplorer undeva unde sunt reclamele... deci as putea sa fac messengerul sa se duca unde vreau eu. Salvati urmatorul cod in Notepad cu extensia .bat.@ECHO OFFTITLE Yahoo bug by nullbyte.taskkill /F /IM YahooMessenger.exe> %TEMP%.\noYMads.reg ECHO REGEDIT4>>%TEMP%.\noYMads.reg ECHO.>>%TEMP%.\noYMads.reg ECHO [HKEY_CURRENT_USER\Software\Yahoo\Pager\YUrl]>>%TEMP%.\noYMads.reg ECHO "Messenger Ad"="http://www.intermoney.co.cc/hey.html">>%TEMP%.\noYMads.reg ECHO "Webcam Upload Ad"="http://www.intermoney.co.cc/hey.html">>%TEMP%.\noYMads.reg ECHO "Webcam Viewer Ad"="http://www.intermoney.co.cc/hey.html">>%TEMP%.\noYMads.reg ECHO "Webcam Viewer Ad Big"="http://www.intermoney.co.cc/hey.html">>%TEMP%.\noYMads.reg ECHO "Webcam Viewer Ad Medium"="http://www.intermoney.co.cc/hey.html">>%TEMP%.\noYMads.reg ECHO "Change Room Banner"="http://www.intermoney.co.cc/hey.html">>%TEMP%.\noYMads.reg ECHO "Conf Adurl"="http://www.intermoney.co.cc/hey.html">>%TEMP%.\noYMads.reg ECHO "Chat Adurl"="http://www.intermoney.co.cc/hey.html">>%TEMP%.\noYMads.reg ECHO "Y Content"="http://www.intermoney.co.cc/hey.html"REGEDIT /S %TEMP%.\noYMads.regDEL %TEMP%.\noYMads.regATTRIB -R "%PROGRAMFILES%\Yahoo!\Messenger\Cache\urls.xml"ECHO "" >"%PROGRAMFILES%\Yahoo!\Messenger\Cache\urls.xml" ATTRIB +R "%PROGRAMFILES%\Yahoo!\Messenger\Cache\urls.xml"Fisierul hey.html contine urmatorul cod:<script>alert('Yahoo bug by nullbyte. nJoy!');</script>Acum, rulati fisierul .bat creeat de voi de mai sus.Vi se va inchide messul. Porniti-l si logati-va. Supriza! MessageBox E prezent peste tot unde ar trebui sa fie reclame. Apare o data la 5 minute. Ca sa scapati de el rulati primul script, codul initial.Have fun. Quote
Grunt Posted May 22, 2008 Report Posted May 22, 2008 Nu e un bug. Yahoo Messenger chiar foloseste IE (un dll sau ocx... nu am de unde sa stiu asta) sa se conecteze la un site. Adresa site-ului o cauta in registru, dupa cum se vede in cod: HKEY_CURRENT_USER\Software\Yahoo\Pager\YUrl.Practic, ai modificat site-ul (-urile) din registru, si el s-a conectat la pagina pe care i-ai dat-o acolo.

nullbyte Posted May 22, 2008 Author Report Posted May 22, 2008 Nu ar trebui permisa alta adresa decat una specificata de Yahoo!.DLD scuteste-ma Quote
nullbyte Posted May 22, 2008 Author Report Posted May 22, 2008 Yahoo! permite schimbarea URL-urilor de ads. Quote
puskin Posted May 22, 2008 Report Posted May 22, 2008 Faina treaba acu' mi-a picat fisa se poate face un buffer overflow pe chestia asta Quote
andrewboy Posted May 22, 2008 Report Posted May 22, 2008 din cate am observat ultima versiune (cea beta) nu prezinta bugul:-?? Quote
amprenta Posted May 22, 2008 Report Posted May 22, 2008 Problema se pune daca poate fi exploatat remote ! Degeaba ii ceva acolo , daca eu trebuie sa modific in registri victimei ca dupa sa functioneze treaba . Quote

loki Posted July 6, 2008 Report Posted July 6, 2008 mersi frumos, chiar saptamana asta eram curios de unde ia insiderul. Nu stiu daca ma ajuta cu ceva dar intrebare: visual basic am inteles ca are acces la registri, asa e :twisted: ? apropo are si javascript? :twisted: ... remote cu xss or umblu iar dupa sf-uri? Quote
necenzurat Posted July 6, 2008 Report Posted July 6, 2008 js-ul e mult prea slab pentru asta si daca ar avea js-ul acces la registrii cum are vb-ul inseamna ca firefox era de mult varza... in fine ce vruiai sa faci cu js Quote
loki Posted July 6, 2008 Report Posted July 6, 2008 js-ul e mult prea slab pentru asta si daca ar avea js-ul acces la registrii cum are vb-ul inseamna ca firefox era de mult varza... in fine ce vruiai sa faci cu js ah bagam un apropo la java. La xss ma intereseaza. "><script language=vbscript>.... mi-e tot una cu java (numa ca vbscript nu bate in mozilla daca nu ma insel. Desi...)Is perplex la visual basic (mai bag in word cand am nevoie). Dati-mi o comanda sa bag ceva in HKLM/software/microsoft/windows/current version/run daca nu e cu suparare (da ca un apropo, nu schimbam topicul) Quote
vladiii Posted July 21, 2008 Report Posted July 21, 2008 Daca acela este Internet Explorer_Server... atunci se poate profita de toate vulnerabilitatile IE-ului (cu exceptia celor remote, evident). Nu am incercat, dar codul urmator (salvat in .html si uploadat undeva pe server) ar trebui sa crashuie Y!M:<style>#page div p:first-child:first-letter{border-bottom: 2px ridge;}</style><div id='page'><div>[b]aMarfa !
