pyLoad: Arbitrary File Deletion via Path Traversal during Encrypted 7z Password Verification

pyLoad is a free and open-source download manager written in Python. Versions before 0.5.0b3.dev97 are vulnerable to path traversal during password verification of certain encrypted 7z archives (encrypted files with non-encrypted headers), causing arbitrary file deletion outside of the extraction directory. During password verification, pyLoad derives an archive entry name from 7z listing output and treats it as a filesystem path without constraining it to the extraction directory. This issue has been fixed in version 0.5.0b3.dev97.

对路径名的限制不恰当(路径遍历)

pyLoad 路径遍历漏洞

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.dev97之前版本存在路径遍历漏洞，该漏洞源于密码验证期间存在路径遍历，可能导致任意文件删除。
