elFinder: Command injection in resize background color parameter when using ImageMagick CLI

elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.67, elFinder contains a command injection vulnerability in the resize command. The bg (background color) parameter is accepted from user input and passed through image resize/rotate processing. In configurations that use the ImageMagick CLI backend, this value is incorporated into shell command strings without sufficient escaping. An attacker able to invoke the resize command with a crafted bg value may achieve arbitrary command execution as the web server process user. This vulnerability is fixed in 2.1.67.

OS命令中使用的特殊元素转义处理不恰当(OS命令注入)

elFinder 操作系统命令注入漏洞

elFinder是Studio 42开源的一个开源的web文件管理器。 elFinder 2.1.67之前版本存在操作系统命令注入漏洞，该漏洞源于resize命令中bg参数未经充分转义即传入shell命令字符串，导致任意命令执行。
