| Описание | An information disclosure vulnerability exists in usr/sbin/miniupnpd in Tomato by Shibby firmware. In the SUBSCRIBE callback handling path, the daemon stores an attacker-controlled callback URI and later constructs the initial NOTIFY request in a fixed 0x400-byte heap buffer. The code uses the return value of snprintf() as the transmit length without checking whether the formatted length exceeded the allocated buffer size. As a result, a sufficiently long callback path can cause send() to transmit bytes beyond the intended 0x400-byte buffer, disclosing unintended heap memory and adjacent message data to the subscribing client.
The current evidence supports LAN-side unauthenticated information disclosure. The callback host is constrained to the requester's own IPv4 address, so the supported impact is memory disclosure back to the subscriber-controlled listener, not arbitrary SSRF. |
