Progress Telerik Report Server Authentication Bypass by Spoofing
CVE-2024-4358 is a critical-severity authentication bypass by spoofing vulnerability in Telerik Report Server from Progress Software, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 10.1.24.514 as the first without the flaw, so updating Telerik Report Server to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on June 13, 2024, which means attacks have been observed in the wild.
Attackers are already exploiting this vulnerability, according to CISA.
What to do
- Update Telerik Report Server to 10.1.24.514 or a later version.
- CISA's required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
- Read the advisory on docs.telerik.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
