UTT Aggressive Buffer Overflow Vulnerabilities

Buffer overflow in UTT Aggressive HiPER 1200GW v2.5.3-170306 timeRangeName parameter allows authenticated attackers with high privileges to cause denial of service through crafted input to the formConfigDnsFilterGlobal function. CVSS score of 4.5 reflects local/adjacent network attack vector and high-privilege requirement, with no confidentiality or integrity impact. No public exploit code or active exploitation confirmed at time of analysis.

Buffer overflow in UTT Aggressive HiPER 810G v3 version 1.7.7-171114 within the notes parameter of the formGroupConfig function enables authenticated administrators to trigger a denial of service condition through a crafted input. The vulnerability requires high-privilege access and cannot result in code execution, but represents a threat to device availability. No public exploit code has been independently confirmed, and this CVE does not appear on the CISA KEV catalog at time of analysis.

Buffer overflow in UTT Aggressive HiPER 810G v3 v1.7.7-171114 ConfigAdvideo function allows authenticated local attackers with high privileges to cause denial of service by crafting malicious input to the timestart parameter. The vulnerability scores low-to-moderate risk (CVSS 4.5) due to strict prerequisites: network access limited to adjacent network only, high privilege requirement, and impact restricted to availability.

Buffer overflow in UTT Aggressive 520W v3 v1.7.7-180627 filename parameter of formFtpServerDirConfig function allows authenticated attackers with high privileges to cause denial of service. The vulnerability requires local network access and high-level administrative credentials; no public exploit code or active exploitation has been confirmed at time of analysis.

Buffer overflow in UTT Aggressive HiPER 1200GW v2.5.3-170306 formArpBindConfig function allows authenticated attackers with high privileges to cause denial of service by supplying a crafted input to the pools parameter. CVSS score of 4.5 reflects limited attack surface (local network access required) and high privilege requirement, though impact is complete availability loss. No public exploit code or active exploitation confirmed at time of analysis.

Buffer overflow in UTT Aggressive 520W v3 firmware version 1.7.7-180627 allows authenticated high-privilege attackers to cause denial of service by supplying crafted input to the addCommand parameter of the formConfigCliForEngineerOnly function. The vulnerability requires administrative-level access and local network connectivity, limiting real-world attack surface despite the buffer overflow class of vulnerability.

Buffer overflow in UTT Aggressive HiPER 810G v3 v1.7.7-171114 formTaskEdit function allows authenticated administrators to cause denial of service through a malformed selDateType parameter. The vulnerability is a classic stack-based buffer overflow (CWE-120) requiring high-privilege local network access; no public exploitation framework has been identified, and CVSS 4.5 reflects the limited scope (DoS only, no code execution or information disclosure).
