MITRE ATT&CK
1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires the attacker to have an authenticated local logon (shell or equivalent) to the infrastructure host running MySQL Server or MySQL Cluster - remote network exploitation is not possible per AV:L. The attacker must hold at minimum low-privilege OS credentials (PR:L); unauthenticated or purely remote exploitation is not applicable. High attack complexity (AC:H) means the attack is not trivially repeatable and likely depends on specific timing, file system state, or environment conditions within the Server: Configurator component. Critically, a separate human user - other than the attacker - must perform an interactive action (UI:R) during the attack window, such as running a configuration task, for the exploit to succeed. Limiting factors: (1) local access requirement eliminates external threat actors without prior footholds; (2) the UI:R dependency requires coordination or timing with another user's activity; (3) AC:H means casual or opportunistic exploitation is unlikely. Only MySQL Server and MySQL Cluster versions 9.7.0-9.7.1 are in scope. |
| Impact | Real-world risk is moderate despite the high-impact CVSS outcome. The local attack vector (AV:L) immediately limits the exploitable population to users who already have shell access to the MySQL host - eliminating remote threat actors without prior compromise. Attack complexity is rated High (AC:H), meaning exploitation is not straightforward and may require timing, specific environment state, or repeated attempts. Low privileges (PR:L) are sufficient but required interaction from a second user (UI:R) adds a social engineering or timing dependency that further reduces reliability. The net CVSS 3.1 score of 6.7 reflects these constraints accurately. No EPSS data was provided, preventing probability-of-exploitation quantification. KEV status is negative and no POC is public, so this is currently a theoretical risk vector. Priority should be elevated only for environments where untrusted low-privileged local users share infrastructure with MySQL 9.7.x instances. Tags include 'Information Disclosure' but the CVSS impact metrics indicate full C:H/I:H/A:H - this discrepancy may reflect Oracle's tagging convention rather than a true information-disclosure-only outcome; the authoritative CVSS metrics indicating full takeover should be treated as the primary risk signal. |
| Exploit ScenarioDerived | A low-privileged local user on the MySQL host waits for or socially engineers a database administrator to invoke a configuration operation through the MySQL Configurator. During this window, the attacker exploits the high-complexity flaw - likely a race condition or unsafe file operation - to redirect or manipulate the Configurator's actions, ultimately achieving full compromise of the MySQL Server or Cluster instance. No public proof-of-concept exists, and the AC:H rating suggests reliable exploitation would require significant attacker effort and environment knowledge. |

Alert meAnalysisAIv1 – Jul 22, 2026
Full takeover of MySQL Server and MySQL Cluster 9.7.0-9.7.1 is achievable via a local, low-privileged attacker exploiting a flaw in the Server: Configurator component, provided a second user interacts during the attack window. The CVSS 3.1 score of 6.7 reflects the high attack complexity and local-only vector, which meaningfully constrain real-world exploitability despite the high-impact outcome (C:H/I:H/A:H). No public exploit code has been identified at time of analysis, and CISA KEV confirmation is absent.
RemediationAI
Apply the patch released as part of Oracle's July 2026 Critical Patch Update (CPU), available via the Oracle advisory at https://www.oracle.com/security-alerts/cpujul2026.html. Oracle has not published a specific patched version number beyond the CPU cycle; organizations should verify the exact patched build through the Oracle support portal. Exact fix version is not independently confirmed from available data - consult Oracle My Support for the specific patched release. Where immediate patching is not feasible, restrict local logon access to the MySQL host to the minimum set of trusted, privileged accounts, as the attack requires an authenticated local session (PR:L). Audit and harden OS-level file permissions on MySQL Configurator-related files and directories to prevent manipulation by non-DBA local users. Enabling mandatory access controls (SELinux, AppArmor) with a MySQL-specific profile can limit privilege escalation pathways from the Configurator component.

Technical ContextAI · show details
The vulnerability resides in the Server: Configurator component of Oracle MySQL Server and MySQL Cluster, versions 9.7.0 through 9.7.1, as identified by CPE strings cpe:2.3:a:oracle_corporation:mysql_server and cpe:2.3:a:oracle_corporation:mysql_cluster. The Configurator is responsible for initial and runtime configuration management of MySQL instances. CWE classification is not provided by Oracle, making precise root-cause categorization difficult; however, the AV:L/AC:H/UI:R vector pattern is consistent with insecure file handling, privilege escalation via configuration race conditions, or symlink-based attacks during configuration operations. The local attack vector confirms the vulnerability is not network-reachable and requires physical or authenticated shell access to the host running MySQL.

DescriptionCVE.org
Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: Configurator). Supported versions that are affected are MySQL Server: 9.7.0-9.7.1; MySQL Cluster: 9.7.0-9.7.1. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where MySQL Server, MySQL Cluster executes to compromise MySQL Server, MySQL Cluster. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of MySQL Server, MySQL Cluster. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H).
