漏洞描述
中文描述:
Bitdefender Total Security是罗马尼亚比特梵德(Bitdefender)公司的一款应用于PC端的主动威胁防护软件。该软件具有防病毒,防火墙,反间谍软件,隐私控制,家长控制功能。还包括System TuneUp等功能。 Bitdefender Total Security 27.0.46.231版本存在后置链接漏洞,该漏洞源于符号链接验证不足,可能导致任意文件删除和权限提升。
英文描述:
A local privilege escalation vulnerability in Bitdefender Total Security 27.0.46.231 allows low-privileged attackers to elevate privileges. The issue arises from bdservicehost.exe deleting files from a user-writable directory (C:\ProgramData\Atc\Feedback) without proper symbolic link validation, enabling arbitrary file deletion. This issue is chained with a file copy operation during network events and a filter driver bypass via DLL injection to achieve arbitrary file copy and code execution as elevated user.
