Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-789: Memory Allocation with Excessive Size Value, where the product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated. In Github.com/contribsys/faktory, software state validation or input boundaries are circumvented during processing.

"details" : "### Summary\nFaktory web dashboard can suffer from denial of service by a crafted malicious url query param `days`.\n\n### Details\nThe 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.\n\n### PoC\nTo reproduce this vulnerability, please follow these steps:\n\nStart the Faktory Docker and limit memory usage to 512 megabytes for better demonstration:\n```\n$ docker run --rm -it -m 512m \\\n -p 127.0.0.1:7419:7419 \\\n -p 127.0.0.1:7420:7420 \\\n contribsys/faktory:latest\n``` \n\nSend the following request. The Faktory server will exit after a few seconds due to out of memory:\n\n```\n$ curl 'http://localhost:7420/?days=922337'\n```\n\n### Impact\n**Server Availability**: The vulnerability can crash the Faktory server, affecting its availability.\n**Denial of Service Risk**: Given that the Faktory web dashboard does not require authorization, any entity with internet access to the dashboard could potentially exploit this vulnerability. This unchecked access opens up the potential for a Denial of Service (DoS) attack, which could disrupt service availability without any conditional barriers to the attacker. \n",
