CVE-2023-29000: Nextcloud Desktop

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server. Starting with version 3.0.0 and prior to version 3.7.0, by trusting that the server will return a certificate that belongs to the keypair of the user, a malicious server could get the desktop client to encrypt files with a key known to the attacker. This issue is fixed in Nextcloud Desktop 3.7.0. No known workarounds are available.

Affected products

• Nextcloud Desktop: from 3.0.0, before 3.7.0 (fixed in 3.7.0)
