Telerik UI for WPF: Deserialization of Untrusted Data

Published Updated By the CyberSecBulletin desk

CVE-2024-10012 is a high-severity deserialization of untrusted data vulnerability in Telerik UI for WPF 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 2024.4.1111 as the first without the flaw, so updating Telerik UI for WPF to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.23% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Telerik UI for WPF to 2024.4.1111 or a later version.
  2. Update progress_telerik_ui_for_wpf_versions to 2024.4.1111 or a later version.
  3. Update UI For Wpf to 2024.4.1111 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 WPF versions prior to 2024 Q4 (2024.4.1111), a code execution attack is possible through an insecure deserialization vulnerability.

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

The underlying weakness: Deserialization of Untrusted Data

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

How developers prevent this class of flaw

  • If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
  • When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
  • Explicitly define a final object() to prevent deserialization.
