CVE-2026-2980
Published: 23 February 2026
Summary
CVE-2026-2980 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 7.3 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 16.2th 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).
Deeper analysis
CVE-2026-2980 is a buffer overflow vulnerability in UTT HiPER 810G devices up to version 1.7.7-1711. The flaw affects the strcpy function in the /goform/setSysAdm file, where manipulation of the passwd1 argument triggers the overflow. It is classified under CWE-119 and CWE-120, with a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), indicating network accessibility and high potential impact.
A remote attacker with high privileges can exploit this vulnerability with low complexity and no user interaction. Exploitation involves sending crafted input to the passwd1 argument, potentially leading to arbitrary code execution and high impacts on confidentiality, integrity, and availability.
Advisories and a proof-of-concept exploit are documented in references including GitHub (https://github.com/7wkajk/CVE-VUL/blob/main/4.md and https://github.com/7wkajk/CVE-VUL/blob/main/4.md#poc) and VulDB (https://vuldb.com/?ctiid.347364, https://vuldb.com/?id.347364, https://vuldb.com/?submit.756130). The exploit has been publicly disclosed and may be used, but no specific patch or mitigation details are provided in the CVE description.
The vulnerability was published on 2026-02-23, highlighting the need for practitioners to assess exposure in affected UTT HiPER 810G deployments.

Why these techniques?
Remote authenticated buffer overflow in web form (/goform/setSysAdm) enabling arbitrary code execution on network device maps directly to T1190 (public-facing app exploitation) and T1068 (post-auth priv esc to code exec).

Directly blocks the overflow by validating/sanitizing the passwd1 argument before it reaches strcpy in /goform/setSysAdm.
Applies memory protections (e.g., ASLR, NX) that prevent successful exploitation of the buffer overflow even if malicious input is supplied.
Limits the high-privilege accounts that can reach the vulnerable setSysAdm function, reducing the population able to trigger the remote overflow.
