Title
The dotCMS administration panel, versions 3.7.1 and earlier, "Push Publishing" feature in Enterprise Pro is vulnerable to arbitrary file upload
Summary
The dotCMS administration panel, versions 3.7.1 and earlier, "Push Publishing" feature in Enterprise Pro is vulnerable to arbitrary file upload. When "Bundle" tar.gz archives uploaded to the Push Publishing feature are decompressed, there are no checks on the types of files which the bundle contains. This vulnerability combined with the path traversal vulnerability (CVE-2017-3188) can lead to remote command execution with the permissions of the user running the dotCMS application. An unauthenticated remote attacker may perform actions with the dotCMS administrator panel with the same permissions of a victim user or execute arbitrary system commands with the permissions of the user running the dotCMS application.
Severity
No CVSS data available.

Title
Hanwha Techwin SSM 1.32 & 1.4 ActiveMQ File Upload RCE
Summary
A client-side remote code execution vulnerability exists in Hanwha Techwin Smart Security Manager (SSM) versions 1.32 and 1.4, due to improper restrictions on the PUT method exposed by the bundled Apache ActiveMQ instance (running on port 8161). An attacker can exploit this flaw through a Cross-Origin Resource Sharing (CORS) bypass combined with JavaScript-triggered file uploads to the web server, ultimately resulting in arbitrary code execution with SYSTEM privileges.
This vulnerability bypasses the server-side mitigations introduced in ZDI-15-156 and ZDI-16-481 by shifting the exploitation to the client-side.
This product is now referred to as Hanwha Wisenet SSM and it is unknown if current versions are affected.

Title
PHP forms generated using the PHP FormMail Generator are vulnerable to unrestricted upload of dangerous file types
Summary
The code generated by PHP FormMail Generator prior to 17 December 2016 is vulnerable to unrestricted upload of dangerous file types. In the generated form.lib.php file, upload file types are checked against a hard-coded list of dangerous extensions. This list does not include all variations of PHP files, which may lead to execution of the contained PHP code if the attacker can guess the uploaded filename. The form by default appends a short random string to the end of the filename.
Severity

Title
Responsive Thumbnail Slider < 1.0.1 - Authenticated (Subscriber+) Arbitrary File Upload
Summary
The Responsive Thumbnail Slider plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type sanitization in the via the image uploader in versions up to 1.0.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload arbitrary files on the affected sites server using a double extension which may make remote code execution possible.

Mitigation
Architecture and Design
Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.[REF-422] [REF-423]
Mitigation MIT-21
Architecture and Design
Strategy: Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
Mitigation
Architecture and Design
Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically. [REF-423]
Mitigation MIT-5
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- For example, limiting filenames to alphanumeric characters can help to restrict the introduction of unintended file extensions.
Mitigation
Architecture and Design
Define a very limited set of allowable extensions and only generate filenames that end in these extensions. Consider the possibility of XSS (CWE-79) before allowing .html or .htm file types.
Mitigation
Implementation
Strategy: Input Validation
Ensure that only one extension is used in the filename. Some web servers, including some versions of Apache, may process files based on inner extensions so that "filename.php.gif" is fed to the PHP interpreter.[REF-422] [REF-423]
Mitigation
Implementation
When running on a web server that supports case-insensitive filenames, perform case-insensitive evaluations of the extensions that are provided.
Mitigation MIT-15
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation
Implementation
Do not rely exclusively on sanity checks of file contents to ensure that the file is of the expected type and size. It may be possible for an attacker to hide code in some file segments that will still be executed by the server. For example, GIF images may contain a free-form comments field.
Mitigation
Implementation
Do not rely exclusively on the MIME content type or filename attribute when determining how to render a file. Validating the MIME content type and ensuring that it matches the extension is only a partial solution.
Mitigation MIT-17
Architecture and Design
Operation
Strategy: Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
Mitigation MIT-22
Architecture and Design
Operation
Strategy: Sandbox or Jail
- Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
- OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
- This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
- Be careful to avoid CWE-243 and other weaknesses related to jails.
CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs
In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
