Tunnelblick 3.3beta20 and earlier relies on argv[0] to determine the name of an appropriate (1) kernel module pathname or (2) executable file pathname, which allows local users to gain privileges via. Rated high severity (CVSS 7.2), this vulnerability is low attack complexity. Public exploit code available and EPSS exploitation probability 27.8%.
Arbitrary file read as root via symlink following vulnerability in Tunnelblick versions 3.3beta26 through 9.0beta01 allows any local user to exploit tunnelblick-helper through the world-accessible tunnelblickd Unix socket to read arbitrary root-owned files. The vulnerability exists because tunnelblick-helper constructs paths to configuration files within user-controlled directories and reads them as root without validating symlinks, enabling attackers to redirect reads to sensitive files. Vendor-released patch available in version 9.0beta02. SSVC framework identifies this as exploitable with publicly available proof-of-concept code but not automatically exploitable.
Tunnelblick 3.3beta20 and earlier allows local users to gain privileges by using a crafted Info.plist file to control the gOkIfNotSecure value. Rated medium severity (CVSS 4.4). No vendor patch available.
The errorExitIfAttackViaString function in Tunnelblick 3.3beta20 and earlier allows local users to delete arbitrary files by constructing a (1) symlink or (2) hard link, a different vulnerability. Rated low severity (CVSS 1.2). Public exploit code available and no vendor patch available.
Race condition in Tunnelblick 3.3beta20 and earlier allows local users to kill unintended processes by waiting for a specific PID value to be assigned to a target process. Rated low severity (CVSS 1.2). No vendor patch available.
Tunnelblick 3.3beta20 and earlier allows local users to gain privileges via an OpenVPN configuration file that specifies execution of a script upon occurrence of an OpenVPN event. Rated medium severity (CVSS 6.9). No vendor patch available.
Tunnelblick 3.3beta20 and earlier relies on a test for specific ownership and permissions to determine whether a program can be safely executed, which allows local users to bypass intended access. Rated high severity (CVSS 7.2), this vulnerability is low attack complexity. No vendor patch available.
Race condition in the runScript function in Tunnelblick 3.3beta20 and earlier allows local users to gain privileges by replacing a script file. Rated medium severity (CVSS 6.2). Public exploit code available and no vendor patch available.
