Detailsinfo

A vulnerability classified as critical has been found in webargs up to 5.1.2. Affected is an unknown functionality of the component JSON Parser. The manipulation as part of a JSON Payload leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in webargs before 5.1.3, as used with marshmallow and other products. JSON parsing uses a short-lived cache to store the parsed JSON body. This cache is not thread-safe, meaning that incorrect JSON payloads could have been parsed for concurrent requests.

The bug was discovered 03/11/2019. The weakness was published 03/12/2019. This vulnerability is traded as CVE-2019-9710 since 03/11/2019. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 5.1.3 eliminates this vulnerability.
