Progress Telerik UI Attack

Released: Mar 09, 2023


High Severity

Attack Type


Older vulnerabilities still being targeted in the wild.

Telerik User Interface (UI) for ASP.NET does not properly filter serialized input for malicious content. Versions prior to R1 2020 (2020.1.114) are susceptible to remote code execution attacks on affected web servers due to a deserialization vulnerability. FortiGuard Labs continue seeing high exploitation activity and attacker attempting to exploit Telerik UI vulnerabilities. Learn More »

Common Vulnerabilities and Exposures

CVE-2019-18935
CVE-2017-11317
CVE-2017-11357
CVE-2017-9248

Background

Telerik UI for ASP.NET is a popular UI component library for ASP.NET web applications. In 2017, several vulnerabilities were discovered, potentially resulting in remote code execution. Attacker has to chain exploits for unrestricted file upload (CVE-2017-11317, CVE-2017-11357) and insecure deserialization (CVE-2019-18935) vulnerabilities to execute arbitrary code on a remote machine. There are two malware campaigns associated with Progress Telerik UI Attack: Netwalker Ransomware and Blue Mockbird Monero Cryptocurrency-mining. CVE 2019-18935 also made it to CISA's top routinely exploited vulnerability list in the year 2020. https://www.cisa.gov/news-events/cybersecurity-advisories/aa21-209a
