How the Exploit Works
The vulnerability arises from an uncontrolled search path element in Salesforce CLI on Windows. This allows an attacker with local access to replace trusted executables with malicious ones. When the system or user runs the executable, it could lead to unauthorized actions such as system compromise or data leakage.
Conceptual Example Code
Consider the following example where an attacker replaces a trusted executable with a malicious one. Here, they name the malicious executable similarly to a trusted file:
# Attacker machine
# Create malicious executable
echo 'echo "You have been hacked!"' > salesforcecli.exe
# Transfer the malicious executable to the target machine
scp salesforcecli.exe user@target:/usr/bin/In the above pseudocode, the attacker creates a malicious executable `salesforcecli.exe` that prints “You have been hacked!” when executed. They then transfer this executable to the target machine, replacing the trusted `salesforcecli.exe`. When a user or system process executes `salesforcecli.exe`, the malicious code runs instead.
Please note that this is a simplified example. Actual exploits may be more complex and difficult to detect.
Steps to Mitigate
To protect your systems from this vulnerability, the best course of action is to apply the vendor patch. Salesforce has released a patch in version 2.106.6 of the Salesforce CLI on Windows. If applying the patch is not immediately possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. It’s crucial to regularly update and patch your systems to prevent such vulnerabilities from being exploited.
