CVE-2021-32742 (GCVE-0-2021-32742)
Vulnerability from cvelistv5 – Published: 2021-07-09 14:00 – Updated: 2024-08-03 23:33

Title
Untrusted data fed into `Data.init(base32Encoded:)` can result in exposing server memory and/or crash
Summary
Vapor is a web framework for Swift. In versions 4.47.1 and prior, bug in the `Data.init(base32Encoded:)` function opens up the potential for exposing server memory and/or crashing the server (Denial of Service) for applications where untrusted data can end up in said function. Vapor does not currently use this function itself so this only impact applications that use the impacted function directly or through other dependencies. The vulnerability is patched in version 4.47.2. As a workaround, one may use an alternative to Vapor's built-in `Data.init(base32Encoded:)`.

Title
Denial of Service
Summary
Vapor is a web framework for Swift. In Vapor before version 4.40.1, there is a DoS attack against anyone who Bootstraps a metrics backend for their Vapor app. The following is the attack vector: 1. send unlimited requests against a vapor instance with different paths. this will create unlimited counters and timers, which will eventually drain the system. 2. downstream services might suffer from this attack as well by being spammed with error paths. This has been patched in 4.40.1. The `DefaultResponder` will rewrite any undefined route paths for to `vapor_route_undefined` to avoid unlimited counters.
