CVE-2018-12088 (GCVE-0-2018-12088)

Vulnerability from cvelistv5 – Published: 2018-06-10 23:00 – Updated: 2024-09-16 20:16

Summary

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.

Severity

No CVSS data available.
