Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-6 Least Privilege good match

prevent

Directly addresses improper privilege management by ensuring service accounts operate with least privilege, preventing escalation from token access.

AC-3 Access Enforcement good match

prevent

Enforces approved access control policies to block unauthorized access to service account tokens due to insecure permissions.

CM-6 Configuration Settings good match

prevent

Mandates secure configuration settings for permissions on service account tokens to mitigate exposure vulnerabilities.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

Vulnerability in network-accessible Kubeslice service allows remote unauthenticated access to service account token due to insecure permissions, directly enabling exploitation of public-facing app for credential access and privilege escalation.

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

Insecure permissions in kubeslice v1.3.1 allow attackers to gain access to the service account's token, leading to escalation of privileges.

Deeper analysisAI

CVE-2024-53350 is a vulnerability in Kubeslice version 1.3.1 stemming from insecure permissions that enable attackers to access the service account's token, facilitating privilege escalation. Assigned CWE-269 (Improper Privilege Management), it carries 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 confidentiality and integrity impacts with no availability disruption.

The vulnerability can be exploited by unauthenticated attackers over the network, though it requires high attack complexity. Successful exploitation grants access to the service account token, allowing privilege escalation within the affected Kubeslice environment.
