CVE-2026-24498
Published: 27 February 2026
Summary
CVE-2026-24498 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Iptime T5008 Firmware. Its CVSS base score is 6.0 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 10.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and IA-8 (Identification and Authentication (Non-organizational Users)).
Deeper analysis
CVE-2026-24498 is an Exposure of Sensitive Information to an Unauthorized Actor vulnerability (CWE-200) affecting EFM-Networks, Inc. IpTIME router models T5008, AX2004M, AX3000Q, and AX6000M. The issue, published on 2026-02-27, enables authentication bypass in firmware versions through 15.26.8 across all listed models.
Unauthenticated remote attackers (AV:N/PR:N) can exploit the vulnerability over the network with low attack complexity (AC:L) and no user interaction (UI:N), resulting in high confidentiality impact (C:H) through exposure of sensitive information. The CVSS v3.1 base score is 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), with no impact on integrity or availability.

Why these techniques?
Authentication bypass on a network-exposed router directly enables remote exploitation of a public-facing application (T1190) to obtain sensitive data without credentials.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
SI-2 requires timely remediation of identified flaws like the authentication bypass in IpTIME firmware versions through 15.26.8, directly preventing exploitation and sensitive information exposure.
IA-8 mandates robust identification and authentication for non-organizational users accessing router management interfaces, countering unauthenticated remote access that bypasses credentials.
AC-3 enforces approved authorizations for logical access to system resources, mitigating authentication bypass vulnerabilities that allow unauthorized exposure of sensitive information.
