Telerik UI for WinForms: Improper Neutralization of Special Elements used in a Command

Published Updated By the CyberSecBulletin desk

CVE-2024-7679 is a high-severity improper neutralization of special elements used in a command vulnerability in Telerik UI for WinForms from Progress Software, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 2024.3.924 as the first without the flaw, so updating Telerik UI for WinForms to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.74% chance of exploitation within 30 days, higher than 55% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Telerik UI for WinForms to 2024.3.924 or a later version.
  2. Update ui_for_winforms to 2024.3.924 or a later version.
  3. Update UI For Wpf to 2024.3.924 or a later version.
  4. Read the advisory on docs.telerik.com for workarounds and exact fixed builds.
  5. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

In Progress Telerik UI for WinForms versions prior to 2024 Q3 (2024.3.924), a command injection attack is possible through improper neutralization of hyperlink elements.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Neutralization of Special Elements used in a Command

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
