Advanced Installer | Before 22.6
How the Exploit Works
The vulnerability arises due to an uncontrolled search path element in Advanced Installer. When run as SYSTEM in certain configurations, the software checks standard-user writable locations for non-existent binaries and executes them as SYSTEM. A low-privileged attacker can exploit this by placing a malicious binary in a targeted folder. When the installer is executed, the attacker’s code is also executed with SYSTEM privileges, leading to arbitrary SYSTEM code execution.
Conceptual Example Code
Consider the following conceptual shell command, which represents how an attacker might place a malicious binary in a targeted folder:
echo "malicious code" > /path/to/target/folder/non-existent-binaryWhen the Advanced Installer is run and searches for non-existent binaries in the path `/path/to/target/folder/`, it would find and execute the malicious binary, resulting in a privilege escalation.
Recommended Mitigation
Users are advised to apply the vendor patch, which upgrades Advanced Installer to version 22.6 or later, as soon as possible. If immediate patching is not feasible, a temporary mitigation would be to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and prevent exploitation. A thorough security assessment should also be performed to ensure no further vulnerabilities exist in your systems.
