6.2.0->6.3.0GitHub Vulnerability Alerts
CVE-2024-45296
Impact
A bad regular expression is generated any time you have two parameters within a single segment, separated by something that is not a period (
.). For example,/:a-:b.Patches
For users of 0.1, upgrade to
0.1.10. All other users should upgrade to8.0.0.These versions add backtrack protection when a custom regex pattern is not provided:
They do not protect against vulnerable user supplied capture groups. Protecting against explicit user patterns is out of scope for old versions and not considered a vulnerability.
Version 7.1.0 can enable
strict: trueand get an error when the regular expression might be bad.Version 8.0.0 removes the features that can cause a ReDoS.
Workarounds
All versions can be patched by providing a custom regular expression for parameters after the first in a single segment. As long as the custom regular expression does not match the text before the parameter, you will be safe. For example, change
/:a-:bto/:a-:b([^-/]+).If paths cannot be rewritten and versions cannot be upgraded, another alternative is to limit the URL length. For example, halving the attack string improves performance by 4x faster.
Details
Using
/:a-:bwill produce the regular expression/^\/([^\/]+?)-([^\/]+?)\/?$/. This can be exploited by a path such as/a${'-a'.repeat(8_000)}/a. OWASP has a good example of why this occurs, but the TL;DR is the/aat the end ensures this route would never match but due to naive backtracking it will still attempt every combination of the:a-:bon the repeated 8,000-a.Because JavaScript is single threaded and regex matching runs on the main thread, poor performance will block the event loop and can lead to a DoS. In local benchmarks, exploiting the unsafe regex will result in performance that is over 1000x worse than the safe regex. In a more realistic environment using Express v4 and 10 concurrent connections, this translated to average latency of ~600ms vs 1ms.
