Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Directly counters the incorrect access control vulnerability in LoxiLB by enforcing approved authorizations for logical access, preventing unauthorized sensitive information disclosure and privilege escalation.

AC-6 Least Privilege good match

prevent

Mitigates the privilege escalation aspect of CVE-2024-53348 by restricting access to the least privileges required, limiting damage from unauthorized access in LoxiLB.

SI-2 Flaw Remediation good match

prevent

Requires timely identification, reporting, and correction of the specific access control flaw in LoxiLB v0.9.7 and prior, directly eliminating the vulnerability via patching.

MITRE ATT&CK Enterprise TechniquesAI

NVD Description

LoxiLB v.0.9.7 and before is vulnerable to Incorrect Access Control which allows attackers to obtain sensitive information and escalate privileges.

Deeper analysisAI

CVE-2024-53348 is an incorrect access control vulnerability (CWE-284) affecting LoxiLB versions 0.9.7 and earlier. LoxiLB is an open-source load balancer, and the flaw allows unauthorized access that exposes sensitive information and enables privilege escalation. The vulnerability received a CVSS v3.1 base score of 7.4 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating high severity due to its potential for remote exploitation with significant confidentiality and integrity impacts.

Remote network-based attackers require no prior privileges (PR:N) or user interaction (UI:N) to exploit the issue, though it demands high attack complexity (AC:H). Exploitation can disclose sensitive data within the LoxiLB environment and allow attackers to escalate their privileges, potentially compromising the load balancer's control plane or associated services.
