framework: Improper Neutralization of Argument Delimiters in a Command

CVE-2024-52301 is a high-severity improper neutralization of argument delimiters in a command vulnerability in framework from Laravel, 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. The record lists versions 6.20.45, 7.30.7, 8.83.28 as the first without the flaw, so updating framework to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 44.8% chance of exploitation within 30 days, which is in the top 1.21% of all scored CVEs.

EPSS places it among the vulnerabilities most likely to be exploited soon.

What to do

  1. Update framework to 6.20.45 or 7.30.7 or 8.83.28 or 9.52.17, whichever matches your release line, or a later version.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Laravel is a web application framework. When the register_argc_argv php directive is set to on , and users call any URL with a special crafted query string, they are able to change the environment used by the framework when handling the request. The vulnerability fixed in 6.20.45, 7.30.7, 8.83.28, 9.52.17, 10.48.23, and 11.31.0. The framework now ignores argv values for environment detection on non-cli SAPIs.

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.
