CVE-2022-31129
Users who pass user-provided strings without sanity length checks to moment constructor are vulnerable to (Re)DoS attacks.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
moment is a JavaScript date library for parsing, validating, manipulating, and formatting dates. Affected versions of moment were found to use an inefficient parsing algorithm. Specifically using string-to-date parsing in moment (more specifically rfc2822 parsing, which is tried by default) has quadratic (N^2) complexity on specific inputs. Users may notice a noticeable slowdown is observed with inputs above 10k characters. Users who pass user-provided strings without sanity length checks to moment constructor are vulnerable to (Re)DoS attacks. The problem is patched in 2.29.4, the patch can be applied to all affected versions with minimal tweaking. Users are advised to upgrade. Users unable to upgrade should consider limiting date lengths accepted from user input.
