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 commercial version supported analysis of PHP and Java code. In order to identify security vulnerabilities that are based on second-order data flows or misplaced security mechanisms, it used abstract syntax trees, control-flow graphs, and context-sensitive taint analysis [7] It could automatically detect 200 different vulnerability types, code quality issues and misconfiguration weaknesses.
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:
The current revision of the PHP manual mentions that the rationale behind magic quotes was to "help [prevent] code written by beginners from being dangerous." [ 2 ] It was however originally introduced in PHP 2 as a php.h compile-time setting for msql, only escaping single quotes, "making it easier to pass form data directly to msql queries". [ 3 ]
On its own, an arbitrary code execution exploit will give the attacker the same privileges as the target process that is vulnerable. [11] For example, if exploiting a flaw in a web browser, an attacker could act as the user, performing actions such as modifying personal computer files or accessing banking information, but would not be able to perform system-level actions (unless the user in ...
Vulnerabilities can only be exploited when they are active-the software in which they are embedded is actively running on the system. [41] Before the code containing the vulnerability is configured to run on the system, it is considered a carrier. [42] Dormant vulnerabilities can run, but are not currently running.
A vulnerability database (VDB) is a platform aimed at collecting, maintaining, and disseminating information about discovered computer security vulnerabilities.The database will customarily describe the identified vulnerability, assess the potential impact on affected systems, and any workarounds or updates to mitigate the issue.
Assume there is an SQL-Injection in an online web shop. The database user of the online shop software only has read access to the database. Further the injection is in a view of the shop which is only visible to registered customers. The CVSS 4.0 base vector is as follows. AV:N as the vulnerability can be triggered over the web
