漏洞简介
BrightStor ARCserve Backup可为各种平台的服务器提供备份和恢复保护功能。
BrightStor ARCserve Backup在处理用户请求时存在漏洞，远程攻击者可能利用此漏洞导致服务器消耗大量磁盘资源。
每次用户试图验证到LGSERVER.EXE都会在D：CA_BABLDdataServerdata ransfer中创建一个文件。该文件扩展名为.USX，格式类似于RWXXX.usx，其中X为0-9或A-F的值。
在协商期间16进制地址(DWORD)0x15到0x18上的第三个报文中值为0x00 0x00 0x00 0x00，然后是CoreDataDB。如果发送了这个报文，就会将上述内容写入到这个USX文件。但如果在0x15到0x18地址所传送的DWORD值为0xff 0xff 0xff 0x7f，就会向USX文件中写入额外2,096,153KB的NULL，导致拒绝服务。
以下为会话示例：
