Description
The RTSPLive555.dll ActiveX control in Pelco Digital Sentry Server 7.18.72.11464 has a SetCameraConnectionParameter stack-based buffer overflow. This can be exploited by a remote attacker to potentially execute arbitrary attacker-supplied code. The victim would have to visit a malicious webpage using Internet Explorer where the exploit could be triggered.
Exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalogue as of 2026.09.04. That is an absence of confirmed public exploitation, not evidence that exploitation has not occurred. EPSS models a 1.7% probability of exploitation activity in the next 30 days.
