CVE-2023-28997 – Nextcloud Desktop: Initialization vector reuse in E2EE allows malicious server admin to break, manipulate, access files
https://notcve.org/view.php?id=CVE-2023-28997
The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server. Starting with version 3.0.0 and prior to version 3.6.5, a malicious server administrator can recover and modify the contents of end-to-end encrypted files. Users should upgrade the Nextcloud Desktop client to 3.6.5 to receive a patch. No known workarounds are available. • https://ethz.ch/content/dam/ethz/special-interest/infk/inst-infsec/appliedcrypto/education/theses/report_DanieleCoppola.pdf https://github.com/nextcloud/desktop/pull/5324 https://github.com/nextcloud/security-advisories/security/advisories/GHSA-4p33-rw27-j5fc • CWE-323: Reusing a Nonce, Key Pair in Encryption •
CVE-2023-27322 – Parallels Desktop Service Improper Initialization Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-27322
Parallels Desktop Service Improper Initialization Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop. An attacker must first obtain the ability to execute low-privileged code on the target host system in order to exploit this vulnerability. The specific flaw exists within the Parallels Service. The issue results from the lack of proper initialization of environment variables. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. • https://kb.parallels.com/125013 https://www.zerodayinitiative.com/advisories/ZDI-23-216 • CWE-665: Improper Initialization •
CVE-2023-27327 – Parallels Desktop Toolgate Time-Of-Check Time-Of-Use Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-27327
Parallels Desktop Toolgate Time-Of-Check Time-Of-Use Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Toolgate component. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the current user on the host system. • https://kb.parallels.com/125013 https://www.zerodayinitiative.com/advisories/ZDI-23-215 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVE-2023-27328 – Parallels Desktop Toolgate XML Injection Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-27328
Parallels Desktop Toolgate XML Injection Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop. An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Toolgate component. The issue results from the lack of proper validation of a user-supplied string before using it to construct an XML document. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor. • https://kb.parallels.com/125013 https://www.zerodayinitiative.com/advisories/ZDI-23-220 • CWE-91: XML Injection (aka Blind XPath Injection) •
