pyLoad CNL Blueprint is vulnerable to Path Traversal through `dlc_path` leading to Remote Code Execution (RCE)

pyLoad is the free and open-source Download Manager written in pure Python. In versions 0.5.0b3.dev89 and below, there is an opportunity for path traversal in pyLoad-ng CNL Blueprint via package parameter, allowing Arbitrary File Write which leads to Remote Code Execution (RCE). The addcrypted endpoint in pyload-ng suffers from an unsafe path construction vulnerability, allowing unauthenticated attackers to write arbitrary files outside the designated storage directory. This can be abused to overwrite critical system files, including cron jobs and systemd services, leading to privilege escalation and remote code execution as root. This issue is fixed in version 0.5.0b3.dev90.

对路径名的限制不恰当(路径遍历)

pyLoad 安全漏洞

pyLoad是pyLoad开源的一个用 Python 编写的免费开源下载管理器。 pyLoad 0.5.0b3.dev89及之前版本存在安全漏洞，该漏洞源于路径遍历漏洞，可能导致任意文件写入和远程代码执行。
