Name of the Vulnerable Software and Affected Versions GeoWebPlayer (affected versions not specified)

Description The GeoWebPlayer websocket server, used as an addon for GeoVision software such as GV-VMS and GV-Cloud, contains a memory corruption issue. The handle connection info function, which processes the connectionInfo command, fails to enforce length limits when copying attacker-controlled JSON strings into fixed-size buffers. This occurs through manual byte-by-byte loops, specifically affecting the key field, which can lead to a buffer overflow.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
