Acronis True Image是新加坡安克诺斯（Acronis）的一款著名的数据备份还原软件。该软件可用于创建驱动器和磁盘映像，并在需要干净系统时可以还原镜像。 Acronis True Image 2020 24.5.22510版本存在安全漏洞，该漏洞源于程序的日志以可预测的模式生成，允许非特权用户创建一个尚未创建的日志文件到反勒索软件服务.exe的硬链接。在重新启动时，这将迫使反勒索软件服务尝试将其日志写入自己的进程，并在共享中崩溃。每次重启都会发生此崩溃。

Vulnerability Description
An issue was discovered in Acronis True Image 2020 24.5.22510. anti_ransomware_service.exe keeps a log in a folder where unprivileged users have write permissions. The logs are generated in a predictable pattern, allowing an unprivileged user to create a hardlink from a (not yet created) log file to anti_ransomware_service.exe. On reboot, this forces the anti_ransomware_service to try to write its log into its own process, crashing in a SHARING VIOLATION. This crash occurs on every reboot.
