    On macOS systems, by utilizing a Launch Agent and loading the viscosity_openvpn process from the application bundle, it is possible to load a dynamic library with Viscosity's TCC (Transparency, Consent, and Control) identity. The acquired resource access is limited without entitlements such as access to the camera or microphone. Only user-granted permissions for file resources apply. Access to other resources beyond granted-permissions requires user interaction with a system prompt asking for permission. This issue was fixed in version 1.11.5 of Viscosity.

  • Jan 14, 2020Viscosity 1.8.2 on Windows and macOS allows an unprivileged user to set a subset of OpenVPN parameters, which can be used to load a malicious library into the mCVE-2020-5180 · Other software · Sparklabs · reported by MITREHigh 7.8

    Viscosity 1.8.2 on Windows and macOS allows an unprivileged user to set a subset of OpenVPN parameters, which can be used to load a malicious library into the memory of the OpenVPN process, leading to limited local privilege escalation. (When a VPN connection is initiated using a TLS/SSL client profile, the privileges are dropped, and the library will be loaded, resulting in arbitrary code execution as a user with limited privileges. This greatly reduces the impact of the vulnerability.)

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
