A buffer overflow occurs in the selDateType parameter of the formTaskEdit function within UTT Aggressive HiPER 810G. Sending an input that exceeds the expected buffer size triggers an out‑of‑bounds write, causing the application to crash and resulting in a denial of service. The weakness aligns with classic buffer copy without bounds checking.

UTT Aggressive HiPER 810G firmware version v3v1.7.7-171114 is the only version listed as affected; no other vendors or product variants are reported.

The CVSS score is not disclosed and EPSS data is unavailable, so an exact severity rating cannot be assigned. The likely attack vector is that an attacker must be able to send a crafted request to the vulnerable formTaskEdit endpoint, which suggests remote exploitation through network access to that function. No official fix or workaround has been published, leaving the vulnerability exploitable until a corrected firmware release is applied. Because the vulnerability is not present in the CISA KEV catalog, no widespread exploitation has been reported to date.
