Code injection is the malicious injection or introduction of code into an application. Some web servers have a guestbook script, which accepts small messages from users and typically receives messages such as: Very nice site! However, a malicious person may know of a code injection vulnerability in the guestbook and enter a message such as:
A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
The Common Attack Pattern Enumeration and Classification or CAPEC is a catalog of known cyber security attack patterns [1] to be used by cyber security professionals to prevent attacks.
A multitude of scoring methods exist across vulnerability databases such as US-CERT and SANS Institute's Critical Vulnerability Analysis Scale but the Common Vulnerability Scoring System (CVSS) is the prevailing technique for most vulnerability databases including OSVDB, vFeed [15] and NVD. The CVSS is based upon three primary metrics: base ...
Common Vulnerabilities and Exposures (CVE) is a dictionary of common names (i.e., CVE Identifiers) for publicly known information security vulnerabilities. CVE's common identifiers make it easier to share data across separate network security databases and tools, and provide a baseline for evaluating the coverage of an organization's security ...
In computer science, a code property graph (CPG) is a computer program representation that captures syntactic structure, control flow, and data dependencies in a property graph. The concept was originally introduced to identify security vulnerabilities in C and C++ system code, [ 1 ] but has since been employed to analyze web applications , [ 2 ...
Static analysis can be done manually as a code review or auditing of the code for different purposes, including security, but it is time-consuming. [7] The precision of SAST tool is determined by its scope of analysis and the specific techniques used to identify vulnerabilities. Different levels of analysis include:
MITRE's CVE project lists roughly 500 vulnerable programs as of June 2007, and a trend analysis ranks it the 9th most-reported vulnerability type between 2001 and 2006. [ 3 ] Format string bugs most commonly appear when a programmer wishes to output a string containing user supplied data (either to a file, to a buffer, or to the user).
