Executive Summary

CVE-2019-25245 is an elevation of privileges vulnerability in Ross Video DashBoard version 8.5.1. It occurs because the DashBoard.exe executable file has improper file permissions that grant the 'Authenticated Users' group 'Modify' or 'Change' rights. This allows any authenticated user to replace the legitimate executable with a malicious one, enabling them to execute arbitrary code with elevated privileges on the affected system. [1, 3]

Impact Analysis

This vulnerability can allow an authenticated local attacker to escalate their privileges by replacing the DashBoard.exe executable with a malicious binary. This can lead to arbitrary code execution with elevated rights, potentially compromising the entire system where Ross Video DashBoard 8.5.1 is installed. [1, 3]

Detection Guidance

This vulnerability can be detected by checking the file permissions of the DashBoard.exe executable on the affected system. On Windows platforms, you can use the command-line tools icacls or cacls to inspect the access control lists (ACLs) of the DashBoard.exe file. Specifically, look for 'Authenticated Users' having 'Modify' (M) or 'Change' (C) permissions, which indicate the vulnerability. Example command: icacls "C:\Path\To\DashBoard.exe" [1, 3]

Mitigation Strategies

To mitigate this vulnerability, immediately restrict the permissions on the DashBoard.exe executable to remove 'Modify' or 'Change' rights from the 'Authenticated Users' group. Ensure that only trusted administrative accounts have write or modify permissions to this file. This prevents authenticated users from replacing the executable with a malicious binary and thus stops privilege escalation via this vector. [1, 3]
