CVE-2024-13188 is a medium-severity Incorrect Privilege Assignment (CWE-266) vulnerability in Escanav Escan Anti-Virus. Its CVSS base score is 4.8 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Services File Permissions Weakness (T1574.010); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-13188 is a vulnerability in MicroWorld eScan Antivirus version 7.0.32 on Linux systems, affecting an unknown functionality within the /opt/MicroWorld/var/ directory of the Installation Handler component. The issue involves incorrect default permissions (CWE-266 and CWE-276), which have been rated as critical with a CVSS v3.1 base score of 5.3 (AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L). The vulnerability was publicly disclosed on January 8, 2025.
Exploitation requires local access with low privileges (PR:L) and low attack complexity (AC:L), with no user interaction needed. A local attacker can manipulate the affected component to exploit the incorrect default permissions, potentially resulting in low-level impacts on confidentiality, integrity, and availability (C:L/I:L/A:L).
Advisories from VulDB and a GitHub disclosure by hawkteam404 detail the issue but note no vendor response despite early contact. No patches or specific mitigations are available, and the exploit has been publicly released, increasing the risk of use by local attackers.

Mitigating Controls (NIST 800-53 r5) AI
Enforces approved authorizations on files and resources so overly permissive defaults cannot be exploited.
Least privilege directly requires that only the minimal necessary privileges are assigned to each actor.
Requires documented, restrictive configuration settings that cover file and directory permissions.
Account management defines and authorizes the exact privileges granted to each account or role.
Separation of duties constrains which privilege combinations may be assigned to any actor.
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.
Directly enforces least-privilege policy definition, management, and review that prevents incorrect privilege assignments.
Hardened baselines and configuration management explicitly require correct default file permissions.
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.
The access-rights control governs the entire lifecycle of privilege assignment, directly eliminating incorrect assignments.
Privileged-access-rights control explicitly requires least-privilege assignment and ongoing validation, directly mitigating CWE-266.
Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.
Access control policy directly prevents incorrect privilege assignment by defining who may receive which rights.
Segregation of duties reduces blast radius of any single incorrect privilege but does not prevent the assignment itself.
Restricting privileged utility programs limits exposure from over-privileged accounts but does not address how privileges are assigned.
