Summary

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 20th 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.

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.

A.5.15 directly requires determining access needs, defining/enforcing topic-specific access control policy and rules (including need-to-know, privilege restrictions, segregation, formal authorization, role-based mapping, and consistency with classification), which stops most incorrect privilege assignments from being exploitable; the bounded remainder is incorrect assignments that arise from flawed implementation of those rules rather than from their absence.

A.5.18's provisioning, review, revocation and SoD rules (esp. a,b,c,f,i,j) directly stop most incorrect privilege assignments from being granted or persisting, with a bounded remainder in flawed implementation of the authorization step itself (see 5.9/5.15 dependency)
