  2. Code injection - Wikipedia

    en.wikipedia.org/wiki/Code_injection

    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:

  3. DLL injection - Wikipedia

    en.wikipedia.org/wiki/DLL_injection

    In computer programming, DLL injection is a technique used for running code within the address space of another process by forcing it to load a dynamic-link library. [1] DLL injection is often used by external programs to influence the behavior of another program in a way its authors did not anticipate or intend.

  4. Arbitrary code execution - Wikipedia

    en.wikipedia.org/wiki/Arbitrary_code_execution

    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 ...

  5. Cross-site scripting - Wikipedia

    en.wikipedia.org/wiki/Cross-site_scripting

    The definition gradually expanded to encompass other modes of code injection, including persistent and non-JavaScript vectors (including ActiveX, Java, VBScript, Flash, or even HTML scripts), causing some confusion to newcomers to the field of information security. [5] XSS vulnerabilities have been reported and exploited since the 1990s.

  6. Uncontrolled format string - Wikipedia

    en.wikipedia.org/wiki/Log4Shell

    Log4Shell (CVE-2021-44228) is a zero-day vulnerability reported in November 2021 in Log4j, a popular Java logging framework, involving arbitrary code execution. [2] [3] The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021.

  8. Heap spraying - Wikipedia

    en.wikipedia.org/wiki/Heap_spraying

    Exploits often use specific bytes to spray the heap, as the data stored on the heap serves multiple roles. During exploitation of a security issue, the application code can often be made to read an address from an arbitrary location in memory. This address is then used by the code as the address of a function to execute.

  9. Dependency hell - Wikipedia

    en.wikipedia.org/wiki/Dependency_hell

    DLL Hell – a form of dependency hell occurring on 16-bit Microsoft Windows. Extension conflict – a form of dependency hell occurring on the classic Mac OS. JAR hell – a form of dependency hell occurring in the Java Runtime Environment before build tools like Apache Maven solved this problem in 2004. [citation needed]
