CVE-2026-36174: n/a
GNCC GP5 v7.1.76 was discovered to store sensitive wireless network information in plaintext during routine operations to the serial console. This issue allows physically-proximate attackers to obtain sensitive information, including network credentials, via monitoring the serial UART interface.
AI Analysis
Technical Summary
CVE-2026-36174 describes a vulnerability in GNCC GP5 v7.1.76 where sensitive wireless network information is stored in plaintext during routine operations to the serial console. This exposure allows physically proximate attackers to obtain sensitive network credentials by monitoring the serial UART interface. The vulnerability is classified under CWE-256 (Plaintext Storage of a Password). There is no indication of a patch or official remediation at this time, and no known exploits in the wild have been reported.
Potential Impact
An attacker with physical access to the device's serial UART interface can obtain sensitive wireless network credentials, compromising confidentiality. There is no reported impact on system integrity or availability. The CVSS v3.1 base score is 4.6 (medium severity), reflecting the requirement for physical access and the confidentiality impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict physical access to devices and secure serial console interfaces to prevent unauthorized monitoring.
