The vulnerability resides in the \u003ccode\u003e/goform/formRemoteControl\u003c/code\u003e file, where manipulation of the \u003ccode\u003eProfile\u003c/code\u003e argument results in a stack-based buffer overflow. This flaw allows unauthenticated remote attackers to potentially execute arbitrary code on the affected device. The vulnerability has a CVSS v3.1 score of 8.8 (HIGH). Publicly available exploits exist, increasing the risk of active exploitation. Successful exploitation could lead to complete system compromise, allowing attackers to gain full control of the device, potentially disrupting network services or using the device as a foothold for further attacks within the network.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies a vulnerable UTT HiPER 1250GW device running a susceptible firmware version.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting the \u003ccode\u003e/goform/formRemoteControl\u003c/code\u003e endpoint.\u003c/li\u003e\n\u003cli\u003eWithin the HTTP request, the attacker includes a \u003ccode\u003eProfile\u003c/code\u003e argument containing a payload exceeding the buffer's expected size.\u003c/li\u003e\n\u003cli\u003eThe device receives the malicious request and attempts to process the \u003ccode\u003eProfile\u003c/code\u003e argument without proper bounds checking.\u003c/li\u003e\n\u003cli\u003eThe oversized payload overwrites adjacent memory on the stack, including return addresses and other critical data.\u003c/li\u003e\n\u003cli\u003eWhen the function attempts to return, it jumps to an address controlled by the attacker (due to the overwritten return address).\u003c/li\u003e\n\u003cli\u003eThe attacker's code is executed, potentially granting them complete control over the device.\u003c/li\u003e\n\u003cli\u003eThe attacker can then use the compromised device for malicious purposes, such as network reconnaissance, data exfiltration, or denial-of-service attacks.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-5544 allows remote attackers to execute arbitrary code on vulnerable UTT HiPER 1250GW devices.
