Last modified

CVE-2023-21405 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. Knud from Fraktal.fi has found a flaw in some Axis Network Door Controllers and Axis Network Intercoms when communicating over OSDP, highlighting that the OSDP message parser crashes the pacsiod process, causing a temporary unavailability of the door-controlling functionalities meaning that doors cannot be opened or closed. No sensitive or customer data can be extracted as the Axis device is not further compromised. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
