CVE-2025-30706
Oracle Mysql Connectors 9.0.0 – 9.2.0
Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-30706 is a high-severity Incorrect Default Permissions (CWE-276) vulnerability in Oracle Mysql Connectors. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Services File Permissions Weakness (T1574.010); ranked at the 46th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-30706 affects the Connector/J component of Oracle MySQL Connectors in versions 9.0.0 through 9.2.0. The flaw is rated at CVSS 7.5 and stems from incorrect default permissions (CWE-276), enabling a network-based attacker to compromise the connectors and achieve full takeover with impacts to confidentiality, integrity, and availability.
A low-privileged attacker with network access over multiple protocols can exploit the issue, though successful exploitation is rated difficult. The attack requires no user interaction and can result in complete control of the affected MySQL Connectors instance.
Oracle's April 2025 Critical Patch Update and the related NetApp advisory address the vulnerability through available fixes for the impacted Connector/J releases.
EPSS for the CVE rose from a low baseline to a peak of 0.0110, indicating emerging exploitation interest after disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Enforces approved authorizations on files and resources so overly permissive defaults cannot be exploited.
Requires least-privilege defaults so that installed files are not world-writable by default.
Requires documented, restrictive configuration settings that cover file and directory permissions.
Enforces access restrictions on changes, including permission settings applied during installation or configuration.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Hardened baselines and configuration management explicitly require correct default file permissions.
Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.
Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.
Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.
