Summary

CVE-2024-27356 is a high-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Gl-Inet Mt6000 Firmware. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked in the top 4.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

CVE-2024-27356 is an information disclosure vulnerability (CWE-200) affecting a wide range of GL.iNet router models and firmware versions, including MT6000 4.5.5, XE3000 4.4.4, MT3000 4.5.0, AXT1800 4.5.0, and numerous earlier releases such as AR300M 4.3.10 and MV1000 3.216. The flaw permits unauthenticated remote actors to retrieve arbitrary files, including logs, by issuing commands to the device.

An attacker with network access can exploit the issue without credentials or user interaction, achieving disclosure of sensitive user information with a CVSS 3.1 score of 7.5. The attack surface is exposed to the network (AV:N) and requires no privileges (PR:N), enabling straightforward retrieval of files that may contain critical configuration or credential data.

EPSS for the CVE rose from a low baseline to a peak of 0.2351 (current value 0.1929), indicating measurable post-disclosure exploitation interest that warrants renewed attention for exposed GL.iNet devices.

MITRE ATT&CK Enterprise TechniquesAI

T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.
T1552.001 Credentials In Files Credential Access
Adversaries may search local file systems and remote file shares for files containing insecurely stored credentials.
T1654 Log Enumeration Discovery
Adversaries may enumerate system and service logs to find useful data.
Why these techniques?

Vulnerability allows downloading files like logs via commands on network devices, enabling command execution (T1059.008), data collection from local system files (T1005), log enumeration (T1654), and access to unsecured credentials in files (T1552.001).

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-200

Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.

addresses: CWE-200

Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.

addresses: CWE-200

Prevents unauthorized exposure of sensitive information by prohibiting untrusted external systems from processing or storing it.

addresses: CWE-200

By enforcing authorization matching prior to sharing, the control reduces the risk of exposing sensitive information to unauthorized actors.

addresses: CWE-200

Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.

addresses: CWE-200

Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.

addresses: CWE-200

Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.

addresses: CWE-200

Retaining and monitoring training records confirms personnel have completed privacy and security awareness training on handling sensitive data, reducing the chance of unauthorized exposure due to lack of knowledge.
