CVE-2024-7292: Telerik Report Server Auth Bypass Flaw

CVE-2024-7292 Overview

CVE-2024-7292 affects Progress Telerik Report Server versions prior to 2024 Q3 (10.2.24.806). The flaw stems from improper restriction of excessive login attempts [CWE-307], allowing attackers to perform credential stuffing attacks against the authentication endpoint. Without rate limiting or lockout enforcement, adversaries can automate large volumes of authentication requests using leaked credential pairs from prior breaches. Successful authentication grants access to report server functionality, including sensitive business reports and administrative capabilities depending on the compromised account.

Critical Impact
Attackers can hijack Telerik Report Server accounts through automated credential stuffing, gaining access to confidentiality, integrity, and availability of the report infrastructure.

Affected Products

Progress Telerik Report Server versions prior to 2024 Q3 (10.2.24.806)
Deployments exposing the Telerik Report Server login interface to networks
Environments where Telerik Report Server accounts reuse credentials from external services

Technical Details for CVE-2024-7292

Vulnerability Analysis

The vulnerability resides in the authentication flow of Progress Telerik Report Server. The server fails to enforce adequate restrictions on repeated failed login attempts against user accounts. This omission enables credential stuffing, where attackers replay username and password pairs harvested from third-party breaches. Each attempt is processed without throttling, account lockout, or progressive delays.

The weakness is classified under [CWE-307] Improper Restriction of Excessive Authentication Attempts. Successful exploitation requires user interaction in the sense that valid credentials must exist, but no privileges are required prior to attack. Compromised accounts expose reporting data, scheduled jobs, and configuration depending on assigned roles.

Root Cause

The root cause is the absence of effective controls limiting the rate or cumulative count of failed authentication requests per account or per source. Telerik Report Server prior to 10.2.24.806 does not apply account lockout thresholds, CAPTCHA challenges, or rate-based throttling sufficient to defeat automated credential stuffing tooling.

Attack Vector

The attack vector is network-based. An adversary scripts authentication requests against the Telerik Report Server login endpoint using a list of breached credentials. Tools such as Hydra, Burp Intruder, or custom Python clients drive parallel attempts. Because the server processes attempts without rate limits, attackers iterate through credential lists at speeds limited only by network and server capacity. Accounts using passwords previously leaked elsewhere are compromised.

No public proof-of-concept exploit is currently listed, and the issue is not on the CISA Known Exploited Vulnerabilities list. Refer to the Telerik Knowledge Base CVE-2024-7292 advisory for vendor technical details.

Detection Methods for CVE-2024-7292

Indicators of Compromise

High volumes of HTTP POST requests to Telerik Report Server login endpoints from a single source or distributed botnet IPs
Authentication logs showing repeated failures across many usernames followed by sporadic successes
Successful logins from geolocations or user agents that do not match historical patterns for the account
Session activity immediately following login that enumerates reports, users, or configuration

Detection Strategies

Aggregate Telerik Report Server authentication logs and alert on failure-to-success ratios that exceed normal baselines
Correlate login failures by source IP, user agent, and target username to identify credential stuffing patterns
Deploy web application firewall rules that flag high-frequency POST traffic to the login URL

Monitoring Recommendations

Forward Telerik authentication and IIS logs to a centralized SIEM for continuous correlation
Monitor for first-time successful logins after sustained failure bursts on the same account
Track outbound report exports and administrative actions following anomalous authentication events

How to Mitigate CVE-2024-7292

Immediate Actions Required

Upgrade Progress Telerik Report Server to version 2024 Q3 (10.2.24.806) or later
Force password resets for all Telerik Report Server accounts and require strong, unique passwords
Enable multi-factor authentication for all Report Server users where supported
Review authentication logs for unauthorized access predating the patch window

Patch Information

Progress addressed CVE-2024-7292 in Telerik Report Server 2024 Q3 (10.2.24.806). Administrators should follow the upgrade procedure documented in the Telerik Knowledge Base advisory and validate that the patched build is running after deployment.

Workarounds

Place Telerik Report Server behind a reverse proxy or web application firewall that enforces login rate limiting and IP-based throttling
Restrict network access to the Report Server login interface using VPN, IP allowlists, or zero-trust network access controls
Integrate authentication with an external identity provider that enforces account lockout, MFA, and impossible-travel detection

bash

# Configuration example - IIS request rate limiting via Dynamic IP Restrictions
appcmd set config /section:system.webServer/security/dynamicIpSecurity ^
  /denyByRequestRate.enabled:true ^
  /denyByRequestRate.maxRequests:10 ^
  /denyByRequestRate.requestIntervalInMilliseconds:2000
