A high-severity vulnerability (CVE-2024-0259) exists in Fortra’s Robot Schedule Enterprise Agent for Windows versions before 3.04, allowing a low-privileged user to escalate privileges to the local system level. 

The issue stems from the agent’s inability to properly protect its service executable, where an attacker can exploit this by replacing the executable with a malicious one and when the service restarts, the malicious executable will run with system privileges, granting unauthorized access and control.

Fortra’s Robot Schedule Enterprise Agent for Windows versions before 3.04 contains a critical privilege escalation vulnerability (CVE-2024-0259) in which an attacker with low privileges can exploit the flaw to gain complete control over the system. 

The vulnerability lies in the agent’s service executable being susceptible to overwriting and by replacing the executable with a malicious one, the attacker can trick the system into running their code with the highest privileges (local system) when the service restarts. 

The adversary is granted unrestricted access to the system’s resources and the ability to carry out actions such as the installation of malicious software or the theft of personally identifiable information.

There is also the possibility that a user with low privileges could overwrite the service executable with their own malicious code due to the vulnerability. 

The malicious code is executed with local system privileges whenever the service is restarted, which gives the attacker the ability to take full control of the system whenever they want. 

It is categorized as CWE-276, which stands for Incorrect Default Permissions, and it achieved a maximum CVSS score of 7.3 due to the fact that it is highly exploitable and has the potential to have a significant impact. 

To address this issue, it is recommended to upgrade to Robot Schedule Enterprise Agent for Windows version 3.04 or higher, which resolves the vulnerability and mitigates the potential for privilege escalation.
