Detailsinfo

A vulnerability was found in S3QL up to 2.26 and classified as critical. This issue affects the function checksum_basic_mapping of the component Checksum Handler. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

S3QL before 2.27 mishandles checksumming, and consequently allows replay attacks in which an attacker who controls the backend can present old versions of the filesystem metadata database as up-to-date, temporarily inject zero-valued bytes into files, or temporarily hide parts of files. This is related to the checksum_basic_mapping function.

The bug was discovered 06/10/2018. The weakness was shared 06/10/2018 (Website). The advisory is shared at bitbucket.org. The identification of this vulnerability is CVE-2018-12088 since 06/10/2018.
