The flaw resides within an unspecified function of the \u003ccode\u003e/goform/ConfigWirelessBase_5g\u003c/code\u003e file, part of the device's Web Endpoint component. This vulnerability is triggered by manipulating the \u003ccode\u003essid\u003c/code\u003e argument supplied to this endpoint, allowing a remote attacker to overflow a buffer. The exploit for this vulnerability has been publicly disclosed and, as such, poses an immediate and significant risk of active exploitation. For defenders, this means internet-exposed UTT HiPER 1250GW devices are vulnerable to unauthenticated remote code execution, granting attackers full control and potentially compromising the underlying network infrastructure.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eInitial Reconnaissance\u003c/strong\u003e: An attacker identifies internet-facing UTT HiPER 1250GW devices and confirms their vulnerable firmware version (up to 3.2.7-210907-180535).\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eExploit Crafting\u003c/strong\u003e: The attacker develops or utilizes a publicly available exploit that crafts a malicious HTTP POST request.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003ePayload Delivery\u003c/strong\u003e: The crafted HTTP POST request is sent to the \u003ccode\u003e/goform/ConfigWirelessBase_5g\u003c/code\u003e web endpoint on the target device.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eArgument Manipulation\u003c/strong\u003e: The request specifically manipulates the \u003ccode\u003essid\u003c/code\u003e argument, supplying an oversized or specially malformed string containing attacker-controlled data, often embedding shellcode.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eBuffer Overflow Trigger\u003c/strong\u003e: Upon processing the manipulated \u003ccode\u003essid\u003c/code\u003e argument, the vulnerable function in the \u003ccode\u003eConfigWirelessBase_5g\u003c/code\u003e component encounters a stack-based buffer overflow.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eArbitrary Code Execution\u003c/strong\u003e: The overflow corrupts memory and diverts program execution to the attacker's injected shellcode, achieving arbitrary code execution with the privileges of the affected process.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eDevice Compromise\u003c/strong\u003e: The attacker gains full control over the UTT HiPER 1250GW device, enabling subsequent malicious activities such as network pivoting, data exfiltration, or establishing persistent access.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eThe successful exploitation of CVE-2026-14721 results in complete compromise of the UTT HiPER 1250GW device, granting the attacker arbitrary code execution capabilities. Given that these devices are typically network infrastructure components (gateways, routers), a compromise can lead to significant network disruption, unauthorized access to internal network segments, data interception, or the use of the device as a pivot point for further attacks.
