Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Embedding Scripts within Scripts An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
- Signature Spoofing by Key Theft An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

| description | The version of the NVIDIA GPU display driver installed on the remote Windows host is 340.x prior to 342.01 or 375.x prior to 376.33. It is, therefore, affected by multiple vulnerabilities : - A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper access controls. A local attacker can exploit this to access arbitrary memory and thereby gain elevated privileges. (CVE-2016-8821) - A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape IDs 0x600000E, 0x600000F, and 0x6000010 due to improper validation of user-supplied input that is used as an index to an internal array. A local attacker can exploit this to corrupt memory, resulting in a denial of service condition or an escalation of privileges. (CVE-2016-8822) - Multiple buffer overflow conditions exist in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper validation of an input buffer size. A local attacker can exploit these to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-8823, CVE-2016-8825) - A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper access controls. A local attacker can exploit this to write to restricted portions of the registry and thereby gain elevated privileges. (CVE-2016-8824) - A flaw exists in the nvlddmkm.sys driver that allows a local attacker to cause GPU interrupt saturation, resulting in a denial of service condition. (CVE-2016-8826) |
