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 Microsoft Edge installed on the remote Windows host is missing Cumulative Security Update 3169999. It is, therefore, affected by multiple vulnerabilities : - A security feature bypass vulnerability exists due to a failure to properly implement Address Space Layout Randomization (ASLR). An unauthenticated, remote attacker can exploit this, by convincing a user to visit a website that hosts crafted content, to bypass the ASLR security feature, resulting in the ability to predict memory offsets in a call stack. (CVE-2016-3244) - Multiple remote code execution vulnerabilities exist due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, via a crafted website or email, to corrupt memory, resulting in the execution of arbitrary code within the context of the current user. (CVE-2016-3246, CVE-2016-3264) - Multiple remote code execution vulnerabilities exist in the Chakra JavaScript engine due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, by convincing a user to visit a specially crafted website or open a specially crafted Microsoft Office document that hosts the Edge rendering engine, to corrupt memory, resulting in the execution of arbitrary code within the context of the current user. (CVE-2016-3248, CVE-2016-3259, CVE-2016-3260, CVE-2016-3265, CVE-2016-3269) - An information disclosure vulnerability exists in VBScript due to improper disclosure of the contents of its memory. An unauthenticated, remote attacker who has knowledge of the memory address where an object was created can exploit this issue to disclose potentially sensitive information. (CVE-2016-3271) - An information disclosure vulnerability exists in the Microsoft Browser XSS Filter due to improper validation of content. An unauthenticated, remote attacker can exploit this, via a website that hosts content with specially crafted JavaScript, to disclose potentially sensitive information. (CVE-2016-3273) - Multiple spoofing vulnerabilities exist due to improper parsing of HTTP or HTML content. An unauthenticated, remote attacker can exploit these to redirect a user to a malicious website having spoofed contents. (CVE-2016-3274, CVE-2016-3276) - An unspecified information disclosure vulnerability exists due to improper handling of objects in memory that allows an unauthenticated, remote attacker to disclose potentially sensitive information. (CVE-2016-3277) |
