Concierge::Sessions versions from 0.8.1 before 0.8.5 for Perl generate insecure session ids
Vulnerability Description
Concierge::Sessions versions from 0.8.1 before 0.8.5 for Perl generate insecure session ids. The generate_session_id function in Concierge::Sessions::Base defaults to using the uuidgen command to generate a UUID, with a fallback to using Perl's built-in rand function. Neither of these methods are secure, and attackers are able to guess session_ids that can grant them access to systems. Specifically, * There is no warning when uuidgen fails. The software can be quietly using the fallback rand() function with no warnings if the command fails for any reason. * The uuidgen command will generate a time-based UUID if the system does not have a high-quality random number source, because the call does not explicitly specify the --random option. Note that the system time is shared in HTTP responses. * UUIDs are identifiers whose mere possession grants access, as per RFC 9562. * The output of the built-in rand() function is predictable and unsuitable for security applications.

Concierge::Sessions 安全漏洞
Vulnerability Description
Concierge::Sessions是Bruce Van Allen个人开发者的一个用户管理系统。 Concierge::Sessions 0.8.5之前版本存在安全漏洞，该漏洞源于generate_session_id函数默认使用uuidgen命令生成UUID，回退使用Perl内置rand函数，这两种方法都不安全，可能导致攻击者猜测session_id并获得系统访问权限。
