Vulnerability Title
Flowintel Arbitrary Log File Path Allows Remote Code Execution via Template Injection
Vulnerability Description
Affected versions of Flowintel allow the LOG_FILE configuration value to be modified through system settings without restricting it to a filename inside the intended log directory.
Because the application constructs the log destination from this configurable value, an administrator could set LOG_FILE to an arbitrary filesystem path. Since attackers can influence logged content, this enables controlled data to be written into unintended files. The upstream commit specifically describes an exploitation chain in which an attacker injects a template into a chosen file and subsequently abuses application rendering behavior to execute code.
The patch removes LOG_FILE from the web-editable settings, introduces validate_log_file_name() to reject absolute paths, traversal, Windows paths, null bytes, and directory components, and centralizes log path construction through resolve_log_file_path().
Version impacted: >=3.3.0

对路径名的限制不恰当(路径遍历)
Vulnerability Title
flowintel 路径遍历漏洞
Vulnerability Description
flowintel是flowintel团队开源的一款威胁情报与威胁分析管理平台。 flowintel 3.3.0版本及以上版本存在安全漏洞,该漏洞源于LOG_FILE配置值未被限制在预期日志目录内,允许通过系统设置将其修改为任意文件系统路径,导致攻击者可能将受控日志数据写入非预期文件,进而通过注入模板并利用渲染行为执行代码。
