CVE-2007-5276

Opera 9 - DNS Rebinding via Failed TCP Connection Handling

Title source: llm
STIX 2.1

Description

Opera 9 drops DNS pins based on failed connections to irrelevant TCP ports, which makes it easier for remote attackers to conduct DNS rebinding attacks, as demonstrated by a port 81 URL in an IMG SRC, when the DNS pin had been established for a session on port 80.
