AI-suggested

To mitigate CVE-2025-26861, European organizations should immediately upgrade RemoteCall Remote Support Program to version 5.3.0 or later, where the vulnerability is fixed. Until patching is possible, implement strict file system permissions to prevent unauthorized users from writing or placing DLL files in the application directory. Employ application whitelisting and code integrity verification to detect and block unauthorized DLLs. Educate users about the risks of running software from untrusted directories and enforce policies that restrict execution of applications from user-writable locations. Network segmentation can limit the ability of attackers to gain local access to systems running the vulnerable software. Additionally, monitor system and application logs for unusual DLL loading activities or unexpected process behaviors. Organizations should also maintain up-to-date endpoint detection and response (EDR) solutions capable of identifying suspicious DLL injection or code execution patterns. Finally, coordinate with RSUPPORT for official patches and advisories to ensure timely updates.

Description

RemoteCall Remote Support Program (for Operator) versions prior to 5.3.0 contain an uncontrolled search path element vulnerability. If a crafted DLL is placed in the same folder with the affected product, it may cause an arbitrary code execution.
