{ "url": "http://public2.vulnerablecode.io/api/vulnerabilities/18089?format=api", "vulnerability_id": "VCID-fcfw-7u4r-ebf8", "summary": "Potential memory exhaustion attack due to sparse slice deserialization\n### Details\n\nRunning `schema.Decoder.Decode()` on a struct that has a field of type `[]struct{...}` opens it up to malicious attacks regarding memory allocations, taking advantage of the sparse slice functionality. For instance, in the Proof of Concept written below, someone can specify to set a field of the billionth element and it will allocate all other elements before it in the slice. \n\nIn the local environment environment for my project, I was able to call an endpoint like `/innocent_endpoint?arr.10000000.X=1` and freeze my system from the memory allocation while parsing `r.Form`. I think [this line](https://github.com/gorilla/schema/blob/main/decoder.go#L223) is responsible for allocating the slice, although I haven't tested to make sure, so it's just an educated guess.\n\n### Proof of Concept\n\nThe following proof of concept works on both v1.2.0 and v1.2.1. I have not tested earlier versions.\n\n```go\npackage main\n\nimport (\n\t\"fmt\"\n\n\t\"github.com/gorilla/schema\"\n)\n\nfunc main() {\n\tdec := schema.NewDecoder()\n\tvar result struct {\n\t\tArr []struct{ Val int }\n\t}\n\tif err := dec.Decode(&result, map[string][]string{\"arr.1000000000.Val\": {\"1\"}}); err != nil {\n\t\tpanic(err)\n\t}\n\tfmt.Printf(\"%#+v\\n\", result)\n}\n\n```\n\n### Impact\n\nAny use of `schema.Decoder.Decode()` on a struct with arrays of other structs could be vulnerable to this memory exhaustion vulnerability. There seems to be no possible solution that a developer using this library can do to disable this behaviour without fixing it in this project, so all uses of Decode that fall under this umbrella are affected. A fix that doesn't require a major change may also be harder to find, since it could break compatibility with some other intended use-cases.", "aliases": [ { "alias": "CVE-2024-37298" }, { "alias":
