5.7 CVE-2024-44744
An issue in Malwarebytes Premium Security v5.0.0.883 allows attackers to execute arbitrary code via placing crafted binaries into unspecified directories. NOTE: Malwarebytes argues that this issue requires admin privileges and that the contents cannot be altered by non-admin users.

CWE-94 : Improper Control of Generation of Code ('Code Injection')
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.) Refactor your program so that you do not have to dynamically generate code. Use automated static analysis tools that target this type of weakness. Many modern techniques use data flow analysis to minimize the number of false positives. This is not a perfect solution, since 100% accuracy and coverage are not feasible. Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results. Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184). Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184). Math component in an LLM framework translates user input into a Pythonexpression that is input into the Python exec() method, allowing codeexecution - one variant of a "prompt injection" attack. Python-based library uses an LLM prompt containing user input todynamically generate code that is then fed as input into the Pythonexec() method, allowing code execution - one variant of a "promptinjection" attack. Framework for LLM applications allows eval injection via a crafted response from a hosting provider. Python compiler uses eval() to execute malicious strings as Python code. Chain: regex in EXIF processor code does not correctly determine where a string ends (CWE-625), enabling eval injection (CWE-95), as exploited in the wild per CISA KEV. "Code injection" in VPN product, as exploited in the wild per CISA KEV. Eval injection in PHP program. Eval injection in Perl program. Eval injection in Perl program using an ID that should only contain hyphens and numbers. Direct code injection into Perl eval function. Eval injection in Perl program. Direct code injection into Perl eval function. Direct code injection into Perl eval function. MFV. code injection into PHP eval statement using nested constructs that should not be nested. MFV. code injection into PHP eval statement using nested constructs that should not be nested. Code injection into Python eval statement from a field in a formatted file. Eval injection in Python program. chain: Resultant eval injection. An invalid value prevents initialization of variables, which can be modified by attacker and later injected into PHP eval statement. Perl code directly injected into CGI library file from parameters to another CGI program. Direct PHP code injection into supporting template file. Direct code injection into PHP script that can be accessed by attacker. PHP code from User-Agent HTTP header directly inserted into log file implemented as PHP script.

Code Injection
An adversary exploits a weakness in input validation on the target to inject new code into that which is currently executing. This differs from code inclusion in that code inclusion involves the addition or replacement of a reference to a code file, which is subsequently loaded by the target and used as part of the code of some application. |

Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. |

Manipulating User-Controlled Variables
This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables. [Probe target application] The adversary first probes the target application to determine important information about the target. This information could include types software used, software versions, what user input the application consumes, and so on. [Find user-controlled variables] Using the information found by probing the application, the adversary attempts to manipulate many user-controlled variables and observes the effects on the application. If the adversary notices any significant changes to the application, they will know that a certain variable is useful to the application. [Manipulate user-controlled variables] Once the adversary has found a user-controller variable(s) that is important to the application, they will manipulate it to change the normal behavior in a way that benefits the adversary. |
