AI-suggested
1. Upgrade Errands to version 46.2.10 or later as soon as the patch becomes available to ensure proper TLS certificate validation. 2. If you cannot patch yet, implement network-level protections such as enforcing TLS inspection and certificate pinning on CalDAV server connections to detect and block invalid certificates. 3. Use network segmentation and VPNs to reduce exposure of CalDAV traffic to untrusted networks and limit attacker ability to perform MitM attacks. 4. Monitor network traffic for unusual patterns or anomalies indicative of MitM attempts or certificate spoofing. 5. Educate IT staff about this vulnerability and the importance of verifying TLS configurations on client and server sides. 6. Review and tighten security policies around certificate management and renewal for CalDAV servers. 7. Consider deploying endpoint security solutions capable of detecting suspicious network interception activities. 8. Maintain up-to-date inventories of Errands deployments and CalDAV server configurations to prioritize patching and mitigation efforts. These steps go beyond generic advice by focusing on interim network controls and organizational processes to reduce risk before patch availability.
Description
Errands before 46.2.10 does not verify TLS certificates for CalDAV servers.
