Summary

CVE-2026-2904 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Utt 810G Firmware. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 28.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Mandates timely identification, reporting, and correction of the buffer overflow flaw in the strcpy function of /goform/ConfigExceptAli to eliminate the vulnerability.

prevent

Requires validation of inputs to the vulnerable web form handler to prevent buffer overflows from malicious remote manipulations.

prevent

Implements memory protections such as stack canaries, ASLR, and DEP to mitigate exploitation of the buffer overflow even if triggered.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Buffer overflow in web management interface (/goform/ConfigExceptAli) of network device enables remote code execution from low privileges (PR:L), directly facilitating T1190 (Exploit Public-Facing Application) and T1068 (Exploitation for Privilege Escalation).
