Description Preview
Beijing Feishu Technology Co., Ltd Feishu v3.40.3 contains an untrusted search path vulnerability (CWE-426). This vulnerability occurs when the application searches for and loads resources or libraries using an untrusted path, potentially allowing attackers to execute malicious code by placing their own versions of these resources in the search path.
Overview
The vulnerability affects Feishu (also known as Lark internationally), a collaboration platform developed by Beijing Feishu Technology Co., Ltd. Version 3.40.3 of the application contains an untrusted search path vulnerability, which could allow an attacker to execute arbitrary code by exploiting the application's insecure library loading mechanism. When the application attempts to load a DLL or other resource, it may search in locations that can be controlled by an unprivileged user, allowing for potential DLL hijacking attacks. This could lead to privilege escalation or unauthorized code execution in the context of the application.
Remediation
Users should update to the latest version of Feishu as provided by the vendor. System administrators should:
- Apply updates or patches released by Beijing Feishu Technology Co., Ltd that address this vulnerability
- Implement the principle of least privilege for application execution
- Consider implementing application control solutions to prevent unauthorized DLLs from being loaded
- Monitor for suspicious activities related to the application's process
- If updates are not immediately available, consider restricting access to the affected application or implementing workarounds as recommended by the vendor
