Race condition in key creation and key rotation exposes private keys of Tang server

CVE ID:CVE-2023-1672
Affected Products:Tang versions prior to 14
Class:Insecure Inherited Permissions (CWE-277)
Discovered by:Brian McDermott

The Tang open source software is used to bind data to network presence. It is commonly used along with Clevis clients to provide for unattended LUKS decryption of server storage volumes within the realms of a network, where a trusted Tang server is situated. CENSUS identified that the Tang software in versions 11, 12 and 13 (and possibly previous versions) is vulnerable to a form of race condition, where the Tang private keys become exposed for a small time window to other users on the same host. The issue is tracked as CVE-2023-1672. Users are recommended to upgrade to Tang version 14 where the issue has been sufficiently addressed.

WhatsApp exposure of TLS 1.2 cryptographic material to third party apps

CVE ID:CVE-2021-24027
Affected Products:WhatsApp Messenger for Android, versions prior to
Class:Exposure of Sensitive Information to an Unauthorized Control Sphere (CWE-497)
Discovered by:Chariton Karamitas

CENSUS identified that versions prior to of WhatsApp for Android allowed third party apps to access WhatsApp TLS 1.2 cryptographic material, as this was stored in "app-specific external storage". On Android 9 and previous versions of Android, the material is exposed to any third party app that bears the READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE permission. On Android 10 a malicious app would also require the requestLegacyExternalStorage attribute to access the files. Through the installation of a malicious app, or alternatively, through the exploitation of a vulnerable app (or Android component) that resides on a WhatsApp user's mobile device, remote actors were able to control the victim user's TLS session cryptographic secrets and could thus perform Man-in-The-Middle attacks to WhatsApp communications. Research has shown that exploitation of this vulnerability can lead to remote code execution on the victim device. CENSUS strongly recommends updating WhatsApp to version or greater. This is a serious vulnerability which could be abused for surveillance purposes.
