The vulnerability resides within the \u003ccode\u003eAddPortMapping\u003c/code\u003e function of the \u003ccode\u003eupnpsoap.c\u003c/code\u003e file, part of the \u003ccode\u003eminiupnpd\u003c/code\u003e component. An attacker on the local network can exploit this vulnerability by manipulating the \u003ccode\u003eNewPortMappingDescription\u003c/code\u003e argument, leading to a buffer overflow. Given that the exploit is publicly available, the risk of exploitation is elevated. This vulnerability is especially critical as it affects end-of-life products, meaning that official patches are unlikely to be released.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker gains access to the local network, either through physical access or compromising a device on the network.\u003c/li\u003e\n\u003cli\u003eThe attacker identifies a vulnerable D-Link DIR-825 router running a firmware version up to 3.00b32.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious SOAP request targeting the UPnP service on the router.\u003c/li\u003e\n\u003cli\u003eThe crafted request includes a \u003ccode\u003eNewPortMappingDescription\u003c/code\u003e argument with a payload exceeding the buffer\u0026rsquo;s capacity in the \u003ccode\u003eAddPortMapping\u003c/code\u003e function within \u003ccode\u003eupnpsoap.c\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe router\u0026rsquo;s \u003ccode\u003eminiupnpd\u003c/code\u003e component processes the SOAP request, triggering the buffer overflow when writing the overly long \u003ccode\u003eNewPortMappingDescription\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe buffer overflow overwrites adjacent memory locations, potentially including critical function pointers or return addresses.\u003c/li\u003e\n\u003cli\u003eThe attacker redirects execution flow to malicious code injected into the overflowed buffer.\u003c/li\u003e\n\u003cli\u003eThe attacker executes arbitrary code on the router, potentially gaining full control of the device or using it as a pivot point to attack other devices on the network.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-7069 allows an attacker on the local network to execute arbitrary code on the vulnerable D-Link DIR-825 router.
