a+HRD: Improper Neutralization of Argument Delimiters in a Command
CVE-2024-3775 is a high-severity improper neutralization of argument delimiters in a command vulnerability in a+HRD from aEnrich Technology, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected a+HRD versions: 6.8; 7.0; 7.1, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.41% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update a\+hrd to 6.8.1039V1055 or 7.0.1141V422 or 7.1.1033V429 or 7.2.1061V36, whichever matches your release line, or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
aEnrich Technology a+HRD's functionality for downloading files using youtube-dl.exe does not properly restrict user input. This allows attackers to pass arbitrary arguments to youtube-dl.exe, leading to the download of partial unauthorized files.

The underlying weakness: Improper Neutralization of Argument Delimiters in a Command
The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.
How developers prevent this class of flaw
- Understand all the potential areas where untrusted inputs can enter your product: parameters or arguments, cookies, anything read from the network, environment variables, request headers as well as content, URL components, e-mail, files, databases, and any external systems that provide data to the application. Perform input validation at well-defined interfaces.
- Directly convert your input type into the expected data type, such as using a conversion function that translates a string into a number. After converting to the expected data type, ensure that the input's values fall within the expected range of allowable values and that multi-field consistencies are maintained.
- When exchanging data between components, ensure that both components are using the same character encoding. Ensure that the proper encoding is applied at each interface. Explicitly set the encoding you are using whenever the protocol allows you to do so.
