CVE-2026-49008: CWE-321 Use of hard-coded cryptographic key in ZTE F689
CVE-2026-49008 is a medium severity vulnerability in the ZTE F689 device involving the use of a hard-coded cryptographic key. An attacker who accesses unencrypted firmware information can obtain credentials used for integrity verification of a specific application function on the device. This could allow the attacker to compromise the integrity of that function. No patch or official remediation guidance is currently available.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-49008) in the ZTE F689 device is due to the use of a hard-coded cryptographic key (CWE-321) embedded in the device firmware. By accessing unencrypted firmware data, an attacker can extract credentials related to the integrity verification of a particular application function. The CVSS 3.1 base score is 6.5, reflecting a network attack vector with low attack complexity, requiring low privileges but no user interaction, and impacting integrity without affecting confidentiality or availability. There is no vendor advisory or patch information available at this time.
Potential Impact
An attacker with network access and low privileges can obtain hard-coded cryptographic credentials from the device firmware, potentially allowing them to compromise the integrity of a specific application function on the device. Confidentiality and availability are not impacted according to the CVSS vector. There are no known exploits in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit access to device firmware and restrict network access to trusted users to reduce risk.
