Telerik Report Server: Deserialization of Untrusted Data

CVE-2024-1800 is a high-severity deserialization of untrusted data vulnerability in Telerik Report Server from Progress Software, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 2024 Q1 (10.0.24.130), 10.0.24.130 as the first without the flaw, so updating Telerik Report Server to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 34.2% chance of exploitation within 30 days, which is in the top 1.57% of all scored CVEs.

Official description

In Progress® Telerik® Report Server versions prior to 2024 Q1 (10.0.24.130), a remote code execution attack is possible through an insecure deserialization vulnerability.

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.
