Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 0.60.1 版本之前的 Perl 版 CallBackery 中，未认证客户端可通过路由中的路径遍历漏洞，读取任意文件的 POD（Perl 对象文档）内容。每个 CallBackery 应用都会将文档插件挂载在路径上，且该挂载优先级高于任何会话检查。该路由会将请求的名称直接传递给，而未进行任何验证。方法会按分割名称，并将各部分拼接为文件路径，因此类似的名称能够跳出目录范围。服务器进程有权读取的任何文件均可被访问。虽然系统仅渲染 POD 内容，但若某个文件包含 POD 指令且未包含标记，则该

Vulnerability Title

CallBackery versions before 0.60.1 for Perl let unauthenticated clients read the POD of any file via path traversal in the /doc route

Source: CVE Program / CVE List V5

Vulnerability Description

CallBackery versions before 0.60.1 for Perl let unauthenticated clients read the POD of any file via path traversal in the /doc route. Every CallBackery application mounts its documentation plugin at /doc, ahead of any session check. The route passes the requested name to Pod::Simple::Search->find without validation. find splits the name on "::" and joins the parts into a file path, so a name such as "..::..::..::etc::motd" escapes @INC. Any file the server process can read is reachable. Only POD is rendered, but a file with a POD directive and no "=cut" is POD to the end of the file.
