Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Server Side Include (SSI) Injection An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
- Cross Zone Scripting An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
- Cross Site Scripting through Log Files An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
- Command Line Execution through SQL Injection An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

| description | The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities : - A flaw exists in the Win32k TrueType font parsing engine that allows an unauthenticated, remote attacker to execute arbitrary code by convincing a user to open a Word document containing malicious font data. (CVE-2011-3402) - A flaw exists in the t2embed.dll module when parsing TrueType fonts. An unauthenticated, remote attacker can exploit this, via a crafted TTF file, to execute arbitrary code. (CVE-2012-0159) - A flaw exists in the .NET Framework due to a buffer allocation error when handling an XBAP or .NET application. An unauthenticated, remote attacker can exploit this, via a specially crafted application, to execute arbitrary code. (CVE-2012-0162) - A flaw exists in the .NET Framework due to an error when comparing the value of an index in a WPF application. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2012-0164) - A flaw exists in GDI+ when handling specially crafted EMF images that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2012-0165) - A heap buffer overflow condition exists in Microsoft Office in the GDI+ library when handling EMF images embedded in an Office document. An unauthenticated, remote attacker can exploit this to execute arbitrary code by convincing a user to open a specially crafted document. (CVE-2012-0167) - A double-free error exists in agcore.dll when rendering XAML strings containing Hebrew Unicode glyphs of certain values. An unauthenticated, remote attacker can exploit this to execute arbitrary code by convincing a user to visit a specially crafted web page. (CVE-2012-0176) - A privilege escalation vulnerability exists in the way the Windows kernel-mode driver manages the functions related to Windows and Messages handling. A local attacker can exploit this, via a specially crafted application, to gain elevated privileges. (CVE-2012-0180) - A privilege escalation vulnerability exists in the way the Windows kernel-mode driver manages Keyboard Layout files. A local attacker can exploit this, via a specially crafted application, to gain elevated privileges. (CVE-2012-0181) - A privilege escalation vulnerability exists in the way the Windows kernel-mode driver manages scrollbar calculations. A local attacker can exploit this, via a specially crafted application, to gain elevated privileges. (CVE-2012-1848) |
