CVE-2026-49005: CWE-916 Use of password hash with insufficient computational effort in ZTE F689
CVE-2026-49005 is a low-severity vulnerability in the ZTE F689 device where the root password hash can be extracted from unencrypted firmware data. The weakness is due to the use of a password hash with insufficient computational effort (CWE-916). This could potentially allow an attacker with access to the firmware to obtain the root password hash. No official patch or remediation guidance is currently available from the vendor. The vulnerability has not been reported as exploited in the wild.
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-49005 affects the ZTE F689 device. It involves the exposure of the root password hash through unencrypted information contained within the device firmware. The password hash uses insufficient computational effort, making it easier to potentially crack. The CVSS v3.1 base score is 2.4, reflecting a low impact primarily on confidentiality. There is no indication of an official fix or patch from ZTE at this time, and no known exploits have been reported.
Potential Impact
An attacker who obtains the firmware can extract the root password hash due to insufficient hashing complexity. This could lead to unauthorized access if the hash is cracked. However, the vulnerability does not affect integrity or availability, and the attack vector requires physical or firmware access, limiting the overall risk. The CVSS score of 2.4 indicates a low impact on confidentiality only.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to firmware images and device physical access to reduce risk. No vendor-provided mitigation or workaround is currently documented.
