#Security Advisory #Patch #Arbitrary File Write #Microsoft #Barracuda #Ivanti #WSDL #NTLM

🛡️WatchTowr Labs has disclosed SOAPwn, an "invalid cast" vulnerability in the .NET Framework that lets attackers abuse WSDL imports and dynamically generated SOAP client proxies to write files and achieve remote code execution. The issue impacts products including Barracuda Service Center RMM, Ivanti Endpoint Manager (EPM), and Umbraco 8. Barracuda addressed the flaw in Service Center RMM 2025.1.1 (CVE-2025-34392, CVSS 9.8) and Ivanti issued fixes in EPM 2024 SU4 SR1 (CVE-2025-13659, CVSS 8.8). Researchers presented the findings at Black Hat Europe after disclosures in March 2024 and July 2025.
