CVE-2022-44748— Knime Server 路径遍历漏洞

Uploading workflows to KNIME Server may override arbitrary file system contents

A directory traversal vulnerability in the ZIP archive extraction routines of KNIME Server since 4.3.0 can result in arbitrary files being overwritten on the server's file system. This vulnerability is also known as 'Zip-Slip'. An attacker can create a KNIME workflow that, when being uploaded, can overwrite arbitrary files that the operating system user running the KNIME Server process has write access to. The user must be authenticated and have permissions to upload files to KNIME Server. This can impact data integrity (file contents are changed) or cause errors in other software (vital files being corrupted). It can even lead to remote code execution if executable files are being replaced and subsequently executed by the KNIME Server process user. In all cases the attacker has to know the location of files on the server's file system, though. Note that users that have permissions to upload workflows usually also have permissions to run them on the KNIME Server and can therefore already execute arbitrary code in the context of the KNIME Executor's operating system user. There is no workaround to prevent this vulnerability from being exploited. Updates to fixed versions 4.13.6, 4.14.3, or 4.15.3 are advised.

Knime Server 路径遍历漏洞

Knime Server是瑞士Knime公司的用于将数据科学工作流投入生产的企业软件。 Knime Server 4.15.3 版本之前存在安全漏洞，该漏洞源于 ZIP 存档提取例程中的目录遍历漏洞可能导致服务器文件系统上的任意文件被覆盖。。
