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 · unedited
In Progress® Telerik® Report Server versions prior to 2024 Q2 (10.1.24.709), a remote code execution attack is possible 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 confidence

Progress Telerik Report Server versions prior to 2024 Q2 (10.1.24.709) contain an insecure deserialization vulnerability that allows unauthenticated remote attackers to execute arbitrary code by submitting crafted serialized objects to the application, leading to complete system compromise.

MitigationUpgrade to Telerik Report Server 2024 Q2 (10.1.24.709) or later. If immediate patching is not feasible, restrict network access to the Report Server interface and implement WAF rules to detect deserialization attack patterns.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Telerik Report Server version
    Access the Report Server web interface and navigate to the Help or About section, or check the version information in the installation directory (such as the assembly version of the main executable or the product's metadata file). Compare the discovered version to 10.1.24.709.
    Affected if The installed version is lower than 10.1.24.709.
  2. Confirm Report Server is network-accessible
    Determine if the Report Server web application is exposed to network requests (internal or external). This can be verified by attempting to access the Report Server URL from a different host or by reviewing network binding configurations in IIS or the embedded web server settings.
    Affected if The Report Server is reachable over the network and the version is below 10.1.24.709.
  3. Verify authentication is not bypassed
    Review the Report Server authentication configuration to confirm that unauthenticated requests are not accepted on any endpoint. Check the web.config file for authentication settings and ensure the Report Server requires valid credentials for all operational endpoints.
    Affected if Unauthenticated access is permitted and the version is below 10.1.24.709.
  4. Inspect for signs of deserialization exploitation
    Review HTTP access logs and application event logs for unusual deserialization patterns, such as requests containing serialized object data (for example, Java serialized objects, JSON with unexpected type indicators, or base64-encoded payloads). Look for suspicious outgoing network connections or unexpected process execution initiated by the web application service account.
    Affected if Suspicious deserialization patterns appear in logs and the version is below 10.1.24.709.

You are affected if the installed Telerik Report Server version is below 10.1.24.709 and the application is accessible over the network without proper authentication controls.

Interim mitigation

Upgrade to Telerik Report Server 2024 Q2 (10.1.24.709) or later. If immediate patching is not feasible, restrict network access to the Report Server interface and implement WAF rules to detect deserialization attack patterns.

Recommended fix High confidence

Telerik Report Server 10.1.24.709 (2024 Q2) or later
