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.

    descriptionThe remote Windows host is affected by multiple vulnerabilities : - Multiple remote code execution vulnerabilities exist due to the Windows Adobe Type Manager Library not properly handling specially crafted OpenType fonts. An attacker can exploit these, by using a crafted document or web page with embedded OpenType fonts, to execute arbitrary code in the context of the current user. (CVE-2015-2432, CVE-2015-2458, CVE-2015-2459, CVE-2015-2460, CVE-2015-2461, CVE-2015-2462) - Multiple remote code execution vulnerabilities exist in various components of Windows, .NET Framework, Office, Lync, and Silverlight due to a failure to properly handle TrueType fonts. An attacker can exploit these, by using a crafted document or web page with embedded TrueType fonts, to execute arbitrary code in the context of the current user. (CVE-2015-2435, CVE-2015-2455, CVE-2015-2456 CVE-2015-2463, CVE-2015-2464) - A remote code execution vulnerability exists due to Microsoft Office not properly handling Office Graphics Library (OGL) fonts. An attacker can exploit this, by using a crafted document or web page with embedded OGL fonts, to execute arbitrary code in the context of the user. (CVE-2015-2431) - A security feature bypass vulnerability exists due to a failure by the Windows kernel to properly initialize a memory address. An attacker, using a specially crafted application, can exploit this issue to bypass Kernel Address Space Layout Randomization (KASLR) and retrieve the base address of the kernel driver. (CVE-2015-2433) - An elevation of privilege vulnerability exists due to a flaw in the Windows Client/Server Run-time Subsystem (CSRSS) when terminating a process when a user logs off. An attacker can exploit this vulnerability to run code that monitors the actions of users who log on to the system, allowing the disclosure of sensitive information which could be used to elevate privileges or execute code. (CVE-2015-2453) - A security feature bypass vulnerability exists due to the Windows kernel-mode driver not properly validating and enforcing impersonation levels. An attacker can exploit this to gain elevated privileges on a targeted system. (CVE-2015-2454) - A security feature bypass vulnerability exists due to the Windows shell not properly validating and enforcing impersonation levels.
