Published: 22 February 2026
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 at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Mandates timely identification, reporting, and correction of the buffer overflow flaw in the strcpy function of /goform/ConfigExceptAli to eliminate the vulnerability.
Requires validation of inputs to the vulnerable web form handler to prevent buffer overflows from malicious remote manipulations.
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
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).
NVD Description
A vulnerability was determined in UTT HiPER 810G 1.7.7-171114. This affects the function strcpy of the file /goform/ConfigExceptAli. Executing a manipulation can lead to buffer overflow. The attack can be launched remotely. The exploit has been publicly disclosed and may…
