Summary

CVE-2025-8178 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Ac10 Firmware. Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 47% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A critical heap-based buffer overflow vulnerability, tracked as CVE-2025-8178 and assigned CWE-119 and CWE-122, affects the Tenda AC10 wireless router running firmware 16.03.10.13. The flaw resides in an unknown function within the /goform/RequestsProcessLaid endpoint; unsanitized input supplied to the device1D argument can corrupt heap memory and is reachable over the network.

An attacker with low-privileged network access can send a crafted request to trigger the overflow. Successful exploitation may allow arbitrary code execution or a denial-of-service condition on the device, consistent with the CVSS 7.4 rating that reflects high impact on confidentiality, integrity, and availability. A public exploit for the issue has already been disclosed.

The EPSS score remains low and unchanged at 0.0113 with no observed upward trajectory after publication. No vendor advisory or patch information is provided in the available references, which include only vulnerability database entries and the vendor’s general site.
