CVE-2024-7315: 
WordPress vulnerability analysis and mitigation

The Migration, Backup, Staging WordPress plugin (WPvivid) before version 0.9.106 contains a security vulnerability related to insufficient randomness in backup filename generation. The vulnerability was discovered by Dmitrii Ignatyev and was publicly disclosed on September 11, 2024, with CVE identifier CVE-2024-7315 (WPScan).

The vulnerability stems from insufficient randomness in the filename creation process when generating backups. The backup files are created with a predictable naming pattern: 'wp-content/wpvividbackups/[SITE-NAME]wpvivid-[HEX_TIMESTAMP][YEAR]-[MONTH]-[DAY]-[HOUR]-[MINUTE]_backup_all.zip'. The hex timestamp is a concatenation of the timestamp in seconds and microseconds between 0 and 999,999, making it potentially predictable (WPScan). The vulnerability has been assigned a CVSS v3.1 base score of 7.5 HIGH (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) (CISA).

If exploited, this vulnerability could allow attackers to bruteforce the exact timestamp and recover backup zip files, potentially leading to unauthorized access to sensitive information contained within the backups (WPScan).

The vulnerability has been fixed in version 0.9.106 of the Migration, Backup, Staging WordPress plugin. Users are advised to update to this version or later to mitigate the security risk (WPScan).
