Vulnerability Title
Faktory: Insecure predictable /tmp/redis.conf enables local Redis config hijack (network exposure / root RCE primitive)
Vulnerability Description
Faktory is a language-agnostic background job server. In versions prior to 1.10.0, the embedded Redis bootstrapper is vulnerable to an insecure temporary file flaw that lets a local unprivileged user hijack the Redis configuration and escalate to root. It writes its startup configuration to a fixed, predictable, world-writable path, /tmp/redis.conf, only creating the file if it does not already exist and never validating it on later boots. Because /tmp is world-writable, a local unprivileged user can pre-create /tmp/redis.conf with attacker-chosen Redis directives before Faktory starts, and Faktory will use the planted file verbatim. Faktory only overrides the unixsocket, dir, and logfile options, leaving directives such as bind, protected-mode, requirepass, and loadmodule attacker-controlled. This lets an attacker silently expose the entire job queue over an unauthenticated network port with no visible error to the administrator. Because the official systemd unit runs Faktory, and the redis-server child it spawns, as root, an attacker can also supply a loadmodule directive to execute arbitrary native code in the root-owned Redis process, escalating from a local unprivileged user to root. This issue is fixed in version 1.10.0.

Vulnerability Title
contribsys Faktory 资源管理错误漏洞
Vulnerability Description
contribsys Faktory是contribsys公司开源的一个后台作业工作服务器。 contribsys Faktory 1.10.0之前版本存在资源管理错误漏洞,该漏洞源于对临时文件处理不安全,将启动配置写入固定可预测的/tmp/redis.conf路径且不验证其内容,可能允许本地低权限用户劫持Redis配置,导致权限提升至root并执行任意代码。
