CVE-2024-1856
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn Progress® Telerik® Reporting versions prior to 2024 Q1 (18.0.24.130), a code execution attack is possible by a remote threat actor through an insecure deserialization vulnerability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is an insecure deserialization vulnerability in Telerik Reporting versions prior to 2024 Q1 (18.0.24.130). A remote, unauthenticated attacker can exploit the vulnerability by sending specially crafted serialized data to the affected Telerik Reporting component, leading to arbitrary code execution on the target system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Telerik Reporting is installedSearch for Telerik.Reporting.dll in the application bin directories, or look for Telerik Reporting folders in the program files, or check the web.config/app.config for Telerik Reporting references.Affected if Telerik Reporting component is found in the environment
-
Determine the installed Telerik Reporting versionRight-click on Telerik.Reporting.dll and select Properties, then view the Details tab for File Version. Alternatively, check the version attribute in the Telerik Reporting assembly reference within your web.config or app.config file.Affected if The version number is lower than 18.0.24.130 (for example, 18.0.0.0, 17.x.x.x, 16.x.x.x, etc.)
-
Check if the Telerik Reporting service is network-accessibleReview your firewall rules and IIS/site bindings to determine if the Telerik Reporting endpoint (typically /api/reports or /Reports path) is exposed to untrusted networks or the internet.Affected if The reporting service is reachable from outside the trusted network or from unauthenticated users
-
Verify if the deserialization handler is enabledCheck the web.config for Telerik Report Viewer handler configurations, specifically looking for serialized object reception endpoints. Search for entries related to ReportService or similar endpoints that accept serialized data.Affected if The service is configured to accept serialized data from unauthenticated remote requests
The environment is affected if Telerik Reporting is installed with a version below 18.0.24.130 and the reporting service is accessible to remote, unauthenticated attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped18.0.24.130
Upgrade Telerik Reporting to version 2024 Q1 (18.0.24.130) or later. If immediate patching is not possible, restrict network access to the reporting services and implement input validation on deserialized data streams.
18.0.24.130 (2024 Q1)
- 1. Identify the current Telerik Reporting version by checking the project references or the installed Telerik Reporting assemblies
- 2. Backup the application and database to ensure rollback capability
- 3. Download Telerik Reporting version 18.0.24.130 (2024 Q1) from the official Telerik website (www.telerik.com) or your Telerik account
- 4. Update the Telerik.Reporting NuGet package in your solution to version 18.0.24.130, or replace the Telerik Reporting DLLs in your bin directory
- 5. Rebuild the application and ensure all dependencies are resolved
- 6. Test the application thoroughly, focusing on report rendering, export functionality, and any custom report definitions
- 7. Deploy the updated application to your production environment
