How the Exploit Works
DLL hijacking is a method wherein an attacker can exploit the loading of DLL files by a program. In this case, the Lenovo Browser is tricked into loading a malicious DLL file instead of the legitimate one. As the browser executes the malicious DLL, the attacker’s code is run, leading to a potential system compromise or data leakage.
Conceptual Example Code
The conceptual example code might look like this:
# Attacker creates a malicious DLL
echo "malicious code" > evil.dll
# Attacker places the malicious DLL in a directory where Lenovo Browser looks for DLLs
mv evil.dll /path/where/lenovo/browser/looks/for/dlls/
# Now, when Lenovo Browser tries to load the DLL, it will load the malicious oneMitigation
It is recommended to apply the vendor patch as soon as possible to fix this vulnerability. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as a temporary mitigation measure. However, these are not long-term solutions and the patch should be applied as soon as it is feasible.
