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 remote Microsoft Exchange server is missing a security update. It is, therefore, affected by multiple vulnerabilities : - Multiple cross-site scripting vulnerabilities exist due to improper sanitization of page content in Outlook Web App. An attacker can exploit these vulnerabilities by modifying properties within Outlook Web App and then convincing a user browse to the targeted Outlook Web App site, resulting in the execution of arbitrary script code in the context of the current user. (CVE-2015-1628, CVE-2015-1629, CVE-2015-1630, CVE-2015-1632) - A spoofing vulnerability exists due to a failure to properly validate the meeting organizer |
