Title
PLANET GS-4210-16P2S Memory Corruption via dispatcher.cgi _readHttpParam
Summary
PLANET GS-4210-16P2S firmware before 3.441b260626 contains a pre-authentication memory corruption vulnerability in the web management interface where the _readHttpParam function copies an oversized HTTP query string without guaranteeing NUL termination, allowing parse_query_string to process attacker-controlled data into a fixed-size stack buffer. An unauthenticated remote attacker can send an oversized GET request to dispatcher.cgi to cause denial of service of the web management interface and potentially trigger memory corruption.
Severity
CWE
- CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
