Public exploitNot knownno public code found

miniupnpc through 2.3.3 contains a one-byte heap out-of-bounds read vulnerability in the minixml parseatt function that allows malicious UPnP gateways to read past buffer bounds via crafted replies. Attackers on the local network can spoof a gateway serving device descriptions or SOAP responses ending in '=' to crash the client.

ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

El vector AV:A con PR:N y UI:N indica red adyacente; el atacante suplanta un gateway UPnP y el cliente se bloquea (crash), lo que encaja con DoS.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
