### Summary Faktory web dashboard can suffer from denial of service by a crafted malicious url query param `days`. ### Details The vulnerability is related to how the backend reads the `days` URL query parameter in the Faktory web dashboard. The value is used directly without any checks to create a string slice. If a very large value is provided, the backend server ends up using a significant amount of memory and causing it to crash. ### PoC To reproduce this vulnerability, please follow these steps: Start the Faktory Docker and limit memory usage to 512 megabytes for better demonstration: ``` $ docker run --rm -it -m 512m \ -p 127.0.0.1:7419:7419 \ -p 127.0.0.1:7420:7420 \ contribsys/faktory:latest ``` Send the following request. The Faktory server will exit after a few seconds due to out of memory: ``` $ curl 'http://localhost:7420/?days=922337' ``` ### Impact **Server Availability**: The vulnerability can crash the Faktory server, affecting its availability. **Denial of...

Faktory is a language-agnostic persistent background job server. Prior to version 1.8.0, the Faktory web dashboard can suffer from denial of service by a crafted malicious url query param `days`. The vulnerability is related to how the backend reads the `days` URL query parameter in the Faktory web dashboard. The value is used directly without any checks to create a string slice. If a very large value is provided, the backend server ends up using a significant amount of memory and causing it to crash. Version 1.8.0 fixes this issue.
